Vacuum flashing is used with this process.
The catalyst in this process is flushed through a vertical pipe called a riser. Hydrogen sulfide is removed from the outcome of this process using hydrodesulfurization. The currently used method of this process uses Y zeolites. Vacuum flashing is used with this process. Shukov invented an early version of this process, whose side products include coke. Its currently used type is the fluid catalytic version. Common outputs of this process include LPG and naphta. It occurs in pyrolysis chambers within refineries. For 10 points, name this process by which long hydrocarbons are broken down into smaller ones, commonly used in the processing of petroleum.
