hello you all in this video we will be working with the previously made pyrolysis oil to make the pyrolysis oil more usable we need to get rid of the acidic compounds that were formed during the pyrolysis process. Therefore we perform a simple extraction with sodium hydroxide and regenerate the naphthenic acids by reacting the sodium slats formed in the extraction with hydrochloric acid so now lets dive straight into the fun. To get started we prepare a alkaline solution by dissolving 25 grams of sodium hydroxide in 250 milliliters distilled water it is important to use distilled water to avoid contamination with other ions furthermore the method I chose here is not the best … It is saver to add some water into the vessel before you add the hydroxide which will prevent the hydroxide from overheating when you fill up to 250 milliliter line the solution we are making is around 10 percent sodium hydroxide. I am working with this exact concentration because in several papers I read on the extraction of naphthenic acids all agreed on around 10 percent base concentration and some hinted that a higher concentration will lead to unwanted sideractions or the formation of a emulsion that will prevent the phase separation which will make it impossible to separate the organic from the water layer to perform the extraction we add 50 milliliters of the ten percent sodium hydroxide solution to 100 milliliters of the pyrolysis oil. This sample of oil I am using was stored for around 2 months to give the oil time to stabilize. This means that compounds like styrene and other reactive monomers had time to polymerize and yield a stable oil after we added the hydroxide solution I am adding a stir bar and closing of the top of the Erlenmeyer flask to prevent crude oil from splashing out during the vigorous stirring. You can´t smell it through your screen but the pyrolysis oil smells really bad …. Plus it is has a lot of aromatic hydrocarbons in it which make it toxic and carcinogenic …. So even if it smelled like roses you would not like to smell it and that’s why I am working in my fume hood so now back to our Erlenmeyer flask. As you can see the vigorous stirring forms a fine emulsion of the alkaline solution and the organic phase which is the oil. This allows us to react nearly all of organic acids in the oil and form their sodium salts which then dissolve into the water layer I continued the stirring for 30 minutes to hopefully react all of the acidic compounds in the oil after the reaction was done I stopped the stirring and prepared a separatory funnel to separate the water and the organic phase. But as usual something had to go wrong and I forgot to close the valve which lead to a spill out. When all the reaction mixture was transferred into the funnel some black carbon precipitate was left in the Erlenmeyer flask. So now we come to the second problem we encounter in this process. In the funnel an emulsions was formed which made it impossible to cleanly separate the layers. To overcome this I added more water and shook the mixture in the funnel. My guess is that this should work by reducing the concentration of base in the mixture thus reducing the emulsifying effect and yielding us two clean layers And it worked the reaction mixture separated into two clean layers with the top one being our mostly deacicified pyrolysis oil and the bottom one water with sodium hydroxide alkali salts of different organic compounds and some pollutants which dissolved into the water. But what would such a workup be without yes you guessed it another problem. Remember the carbon precipitate in the Erlenmeyer flask turns out that the whole mixture is full of fine carbon particulate that clocks the valve of the separatory funnel which left me with the most undesirable option…. separating by hand with a pipette. While I am pipetting of the water layer there are some things I want to discuss. I will redo this experiment because it is an important analysis step by determining the percentage of acidic compounds in the oil but the next time I will distill the oil first before performing the extraction. A distillation reduces the viscosity of the oil by separating the lower boiling fractions in the oil from the paraffin’s which make the oil that viscous. The other thing is that the carbon particulate is left in the distillation flask thus making it easier to work with the oil. The high boiling paraffin´s can then be dissolved in chloroform and their acidity can then be easily determined. So now back to our naphthenic acids. After the separation the water layer is filtered to get rid of the fine carbon particulate. I used a vacuum filtration but a simple gravity filtration works as well. I don’t know how all of this carbon gets into the oil but my guess is that unstable compounds formed in the pyrolysis brake down under the elimination of nitrogen water carbon dioxide and carbon. The carbon particles then sticks together to form bigger carbon lumps that make the oil this hard to work with. After the filtration the now cleaner filtrate is transferred into a beaker to perform the precipitation of the naphthenic acids. Interestingly the water layer is now pitch black which could be due to very small carbon particles that were not filtered out or the dissolved compounds give that color to water phase. Anyhow we want the free naphthenic acids therefore we add a stir bar to our filtered water layer. To regenerate the in water insoluble naphthenic acids we need to lower the ph into a highly acidic region where the sodium salts convert into the free carbonic acids. For this I am using concentrated hydrochloric acid because it has a low boiling point is easily washed away with water and has no oxidizing effect like sulfuric acid. When the acid is added you can see white clouds of naphthenic acid that form but are quickly dissolving back into the still alkaline solution. This happens because the hydrochloric acid first has to react all the hydroxide ions into water before it can react with the sodium naphthenate to regenerate the free organic acid and sodium chloride So you might have noticed that I am using my real voice for this video and I want to know what you my viewers think about this choice which one do you like better? The robotic voice or my one. Please leave a comment to tell me your opinion so I can go on with the way that you like the most. Secondly we are now nearly at 6 thousand subscriber and I wanted to thank you all for your support comments and interest in my work despite the long time between my videos. When you think no more naphthenic acid is crashing out you can check the ph using an indicator paper in my chase the red shows that the solution is now highly acidic just how it needs to be. An interesting fact about naphtanates is that the aluminum salts of naphthenic acids are used to produce napalm. Which I will explore in a future video just because it is too much fun to make your own real napalm. After the conversion into free carbonic acids is done the stirring is stopped and the naphthenic acid is filtered off. Again I am doing this with vacuum filtration but you can also use a simple gravity filtration. To get rid of any salts and hydrochloric acid the precipitate is washed several times with distilled water. After this the acids are dried on the pump for 3 minutes to get rid of as much water as possible It is important to note that the filtrate has to be disposed of properly because there are still traces of many pollutants in it that are harmful to microorganism fish and plants. The Canadian oil sand industries biggest waste output is such water that is polluted with traces of hydrocarbons aromatic compounds and naphtanates. Over the years there have been several studies linking this cocktail of pollutants to cancer and other illnesses in humans. This information is to underline the importance that such chemical waste isn’t just poured down the drain. I will repeat this process on a larger scale and work up the produced naphthenic acid analyze its properties and synthesize some aluminum nahptenate to make some napalm but for now that’s it The next video is already filmed and is about the further insulation of the pyrolysis reactor to make it more efficient so have fun and don’t kill your self
You could have filtered the solution before seperating the layer, often solids encurage the formation of an emulsion. Sometimes it helps to add CaCl2 to the aqueous phase to make it more polar.
Another option is text on screen with no voice. Also some ai based TTS systems may exist that sound much better. Or just keep doing it like this video. Either way you're fine.

Hello Sir very intersting your video... I have a question... how much ácid HCL do you add to the oil, and what concetration is the acid i have 37% HCL acid, is ok... ?
thanks for the videos! i like them better with your real voice haha. i am studying pyrolysis of plastic to fuel for my phd so it is helpful to see videos of it being done at a bench scale (i think this would be considered bench scale??) . I'll be using a micro-reactor, but im interested in seeing how this can be done at an industrial level.
Your voice sounds amazing, soft and manly at the same time. I have no idea why you used robotic voice before, your voice is superior even to most youtubers.
I really love you videos, they're extremely well explained and informative at the same time! I think you'd need a cyclone at the pyrolysis part in order to overcome the problem the carbon residue presented here. This way, you'd filter out the carbon black before it hits the destillation process which might make it a little easier. Btw, use your own voice it's more neutral than this robotic stuff. Greetings from Germany.
I have evaporated some LDPE plastic inside an old paint tin serving as a pyrolysis reactor. I got four products as a result: Inside of the collection glass jar. 1.) transparent liquid, which smells terrible but doesn't burn. 2.) brown liquid, which smells terrible and burns very good with some black smoke. 3.) solid yellow stuff, swimming like a blob inside of the liquid, which burns also. Inside of the tin pyrolysis reactor. 4.) black oily stuff left inside of the tin. Very likely could be further reduced, but my camping stove run out of gas. What is it all?
Very interesting! Do you know if it is possible to DIY hydrotreated vegetable oil (hvo) as a diesel substitute? Maybe waste vegetable oil from restaurants could be used, abd if we could reduce the viscosity by hydrotreatinc it, it could be easier to use as a fuel in diesel engines. Additionally, did I understand correctly that one could use wood for pyrolisis, instead of plastic?
Your voice and accent are quite reassuring and relay your competence. Keep it please. About the carcenogenic gasses and wasteproducts; do you think this negates the benefit of recycling? And if so. How would you weigh it? Recycling plastics and reusing them as fuel is amazing, splendid and worthwhile, if and only IF the resulting toxidity from the byproducts do not outweigh the benefits. Could you explore this perhaps? Highest regards, Mac
I have a habbit of putting a beaker below a separating funnel, always. If I forgot to check the valve it can save the day. More than often you need some container to drain liquids anyway, so why not do that always and before filling it.
Congrats for the great video! Would you please share what would be a "proper disposal" of the precipitation? What do you do with the water after filtering out the precipitation?

sir, you need to know , you should'nt use directly NaOh on pyrolysis oil. It makes organics reactions,i think you receive some high molecular alcohols or esters. You should first make separations of pirolysis oil and make dilution. Check how to research acid number. Good luck
I made my pyrolysis only to 320 degree Celsius with selected products without PVC = my product is Yello clean diesel/kerosene with some of Paraffin - I will use it only to cook or heat water

but if you want it you can make it!

sir, you need to know , you should'nt use directly NaOh on pyrolysis oil. It makes organics reactions,i think you receive some high molecular alcohols or esters. You should first make separations of pirolysis oil and make dilution. Check how to research acid number. Good luck
I made my pyrolysis only to 320 degree Celsius with selected products without PVC = my product is Yello clean diesel/kerosene with some of Paraffin - I will use it only to cook or heat water
If you wanted to break the emulsion easily, why not just add brine water? Works for me!
Sehr interessanter Kanal. Ist das nur dein Hobby? oder bist du Chemiker, Verfahrenstechniker,.... ?
Reines Hobby :D
@@HazelChem definitv nen cooles hobby, weiter so!
your natural voice is preferred
Your voice is better than AI
well done mate
you dont mention about ratio hcl
Your voice is good
you got a nice narration voice
Human voice is better than that robot voice. Your voice sounds great to me!
I like the voice. But there are occasion where you can have a narrator and it works too. I'd say mix it up.
