The currently available literary evidence on general types of experime
ntal molecular-weight distributions of Fischer-Tropsch synthesis produ
cts have been considered. The effect of catalyst compositions and Fisc
her - Tropsch synthesis operating conditions on the type of molecular-
weight distribution has been discussed. Possible mechanisms of carbon
chain growth and termination in the Fischer-Tropsch synthesis have bee
n discussed using the available information on molecular-weight distri
butions. Bibliography - 94 references.
