Catalytic cracking of hydrocarbons
HTML-код
- Опубликовано: 27 апр 2013
- The cracking of heavy hydrocarbons is one of the fundamental processes in the petrochemical industry. In this experiment a simple model of the reaction is presented, employing liquid paraffin as a source of heavy alkanes and crushed clay pots as the catalyst. The gaseous products are collected in test tubes over water. Then, it is demonstrated that the gas is composed of flammable hydrocarbons and that it contains unsaturated compounds.

"Through the fire and flames" by Dragonforce (this is a slower instrumental version)
Hegelrast all i came here for !
im not even watching the experiment.... im just enjoying the piano
Surely 😂
At last a useful video about cracking of hydrocarbons. This is one I can use in my chemistry lessons at high school. It is better than any demstration I can do by myself.
Thanks very much.
Shuuuushhhhh
After ten whole years this is still the best video on catalytic cracking 👏👏
dude on the piano needs to chill man , hes taken on mozart over there , in a tune to the death
Oh, NOBOX, funny to randomly stumble on you here! It's a small world...
(And the music is actually a piano cover of Dragonforce's "Through the Fire and the Flames", a speed metal song known for being played ridiculously fast. Just take a look at the original...)
+piranha031091 lol so funny , ive seen this kinda thing before didnt realize this was one of them
Surleyyy 😆
Don't change anything! This is part of the UK's GCSE syllabus. Adding extra information will over complicate what is a succinct and informative demonstration. Well done!
This piano has no business going this hard. Great vid
Amazing video! I knew of this process but was completely unaware it could be implemented with shattered flower pots or pumice! If gas prices keep going up there will be an underground movement of people cracking paraffin wax and Vaseline! LOL
Great idea!
I wonder if waste motor oil will work?
:-)
through the fire and flames on piano,yeah!
Always cool to get an insight on the chemical processes used in industry.
I learned a lot from this video especially about common materials used for catalysts
CONGRATULAZIONI! Bellissima esecuzione dell'esperimento e fantastico video!!! MC
I love the song!!!! Cool video also.
Nice experiment! Nice video! :)
Exellent video!
Very useful experiment !
Through the fire and flames? Hahahahahaha amazing
bellissimo! wonderfull!!!
thank you for the great vedio
in a flame the reaction is much simpler, it is just plain combustion to CO2 and H2O... However, there is a non-catalytic variant of the cracking which occurs at much higher temperature (with a radical-based mechanism)
thanks, it was intended :D :D :D I hoped someone noticed
just amazing!! what else can I say??
Great Video. I agree with Scary mamma & Han Vermaat
wonderful :)
Awesome
you are right, I had the slides ready, but the video was too long, I had to cut something... As a rule I want to keep the videos as short as possible, if possible less than 5 min... This was over 8 min in my first version.
Anyway, before or after I will make a specific video about bromine addition to double bonds (I have a specific idea in mind) - And the baeyer test can be easily found on any organic chem textbook....
really nice!... we're doing an experiment related to these reactions in a science fair... This video has helped a lot.

do you have a journal about this?
Wow Great.
If i wanted to convert plastics into crude oil what catalysts do you recommend?
Thank you
Kitty litter that your cat shits in is a zeolite and is used as a catalysts to convert plastics hope this helps.
@@barsos1 dont think he will ever get the variety of hidrocarbons in crude oil but it might liquify and break the polymer with enought heat. or just make organic char, wichever comes first.
Does this also happen in candle flame?
Can cyclopentadiene be cracked this way
can we run similar experiments on biodiesel?
Cool
What about pearlite is’nt that also aluminum silicate
Thank you! This video has helped me a Lot~~Jane E (using father's phone)
Why is "Through the fire and flames" playing for this video..
What is the song in this video?
Excelent! Which gases you have collected? If You use hydrocarbon there is just H and C, right? Hydrogen go to the collecting tubes, but Carbon stay in the reactor, like carbon deposits?
***** Hm... Thank you, I donot know this. But how we can split it into its elements?
***** Ok, I will. Thanks! Steam reforming can split hydrocarbons, right? But why use catalysator for hydrocarbon cracking, maybe this lowers temperature for reaction?
Thanks a lot! I was confused with this, what is with carbon, no body can tell me... But, how CO2 can react with water, how to do this? (my English not so good, sorry) :) I will watch your videos when I find free time...
No, you say "The CO can be reacted again with water to get CO2 and more hydrogen". I want to ask how CO react with water but I make error, wrote "CO2" instread "CO" :)
Maybe on the same way like previous reaction of steam reforming, CO+H2O+ HEAT make CO2+H2?? Is this economical if we use this gases just for heating (no need for hydrogen production) because CO and H2 both are combustible?
Broken clay pots to crack and vaporize fuel with exhaust heat?
Looks like catalytic converter is on the wrong end!
Hmmmmm..... sounds like you may be referring to a HCS(hydrogen cracking system) where hydrocarbon vapors are fed into a tub heated to high temps to create hydrogen molecules.
People are using a system like this to improve gas mileage tremendously.
I had one and it worked but the tube kept disintegrating with the heat from the manifold. Back to the drawing board.
hi ....plz can u explain more details about how people are using a system like this to improve gas mileage and what are the components of ur system ? thnx
In ambient pressure and in the absence of presulfided catalysts??? its not real i think.
But then that would be thermal cracking which would be less efficient.
what the piano song called?
Through the fire and flames By Dragon force
Matthew Chow thank u
Whats the song name
Through the Fire and the Flames - Dragonforce
Kaneki Ken its called ANNOYING!
Quite good but ExCptionally annoying music
844 844 seriously guy? Why don't you try listening to some DragonForce cuz that's what this is a cover of. See the comment below, and good luck playing that on piano...
Really u uncultured brat, fuck you

But if you can't measure it, if you can't express it in numbers, your knowledge is unsatisfactory." W.T. Lord Kelvin. Worse still, not giving exact amounts prevents others from verifying what you do, that violates the fundamental principle of the scientific method.

Пианисты закройте уши
This video was kinda boring but the music was LIIITT💯💯🔥🔥🔥🔥🔥👌🏿👌🏾👌🏽👌🏼👌🏻👌❤️☺️😂
You SUCC :v
dislike this comment
Y yall so mean
Y R U SO GEDIK
i love you balqis
Great information. But for crying out loud, remove that insane music!!!!
Haskell Corporation FUXK U TOO UNCULTURED BRAT ITS CALLED THROUGH THE FIRE AND THE FLAMES
The back ground music is Narley man.
