1. How ZSM-5 works on FCC gasoline composition.

Author

DE GRAAF, BART, ALLAHVERDI, MEHDI, EVANS, MARTIN, and DIDDAMS, PAUL

Subjects
*CRACKING process (Petroleum industry), *PROPANE
Abstract

The article discusses the applicability of ZSM-5 additives on fluid catalytic cracking (FCC) units and propane dehydrogenation (PDH) units and in the balancing between matrix and zeolites and rare earth.

2. Hydrogen transfer and ZSM-5 in maximising propylene.

Author

DE GRAAF, BART, ALLAHVERDI, MEHDI, RADCLIFFE, CHARLES, EVANS, MARTIN, and DIDDAMS, PAUL

Subjects
*ZEOLITE catalysts, *PROPENE, *GASOLINE & the environment, *LIQUEFIED petroleum gas, *BASE catalysts
Abstract

The article discusses the use of ZSM-5, a chemical belonging to zeolite family, at high concentrations to maximise propylene from the fluid catalytic cracking (FCC) unit to accommodate the need for increasing propylene demand. Topics discussed include Hydrogen transfer in the FCC, role of ZSM-5 on Liquified Petroleum Gas (LPG) yield and gasoline composition, and effects of ZSM-5 and base catalyst on gasoline composition.

3. 'Snakes and ladders' for maximising propylene.

Author

DE CRAAF, BART, ALLAHVERDI, MEHDI, EVANS, MARTIN, and DIDDAMS, PAUL

Subjects
*PETROLEUM chemicals, *PROPENE manufacture, *FEEDSTOCK, *XYLENE, *PLASTICS, *POLYPROPYLENE, *ACRYLONITRILE, *PROPYLENE oxide
Abstract

The article offers information on the construction of new fluid catalytic cracking (FCC) units in growth regions including Asia and the Middle East as petrochemical FCC units to produce propylene from heavy residual feedstocks. It mentions that the demand for petrochemicals is increasing in Asia due to a shortfall in mixed xylenes and propylene production. It also mentions that propylene is a key chemical for plastics such as polypropylene, acrylonitrile and propylene oxide derivatives.
