CATALYTIC REFORMING Process,Catalysts and Reactors

SELECTIVITY
• Desired yields are:
– hydrogen
– C 5 + reformate
– low benzene
• Benzene
– yield can be minimised by pre-fractionating the
precursors (MCP, CH, nC6P) which are present in the
fraction boiling between 70 to 85°C
– benzene is also produced by the hydrodealkylation of
alkyl benzenes
• Loss of desired yields is caused by cracking
– hydrocracking involving the metal plus acid sites
– hydrogenolysis involving the metal in the presence of
hydrogen
