Can you guys explain what a catalyst is and how it is used in oil refining? Is a catalyst just some time of chemical they add to oil to break it down? The things I'm curious about are mainly fluid cracking catalysts and hydro processing catalysts and how they work.
It accelerates/facilitates a reaction...is the best I can describe it. You'd have to get into each specific example.
In terms of FCC, the catalyst is a powder substance that 'flows' with the feed into the unit . The powder+feed is then flung around in a reactor via cyclones and then the powder goes to the re generator to be burned and recirculated. That's your basic FCC unit. There are many variations of this. The catalyst make-up varies but a big component are rare earth metals.
Hydrocracking? I know they are fixed bed reactors, but I have no idea on what the type of catalyst is. I think they are pellet form?
