Catalytic Cracking: Fluid Catalytic Cracking And Hydrocracking

Catalytic cracking process was developed in1920 by Eugene Houdry for upgradation of residue

was commercialized latter in 1930. Houdry process was based on cyclic fixed bed configuration.

There has been continuous upgradation in catalytic in catalytic cracking process from its incept

of fixed bed technology to latter fluidized bed catalytic cracking (FCC).The feed stock for

catalytic cracking is normally light gas oil from vacuum distillation column. Catalytic cracking

cracks low value high molecular weight hydrocarbons to more value added products (low

molecular weight) like gasoline, LPG Diesel along with very important petrochemical feedstock

like propylene, C4 gases like isobutylene, Isobutane, butane and butane.
