Product distributions in Fischer-Tropsch Synthesis are modelled fairly well by simple, irreversible polymerization kinetics, with a constant chain growth probability with changing chain length. A major discrepancy is low C/sub 2/ yields during synthesis of liquid hydrocarbons, associated with selective reincorporation of ethylene in the chain growth process. With major addition of olefins, such as ethylene, synthesis can be directed toward stoichiometric addition (hydroformylation). And at still higher levels of olefin, hydropolymerization occurs. Intervention of a strong olefin conversion function, such as the ZSM-5 zeolite, can sharply alter the product distribution. This demonstrates the importance of olefins as intermediates in the chain growth process; accurate models must account for reversibility of olefin formation.
