ABSTRACT:

The influence of pre-treatment of a given Fischer-Tropsch catalyst of ion/vanadium, caused by reduction and moulding, on activity, selectivity and mechanical stability during synthesis was studied. The dependence of product spectrum on yield and temperature was also established.  Furthermore the consequences of a partial poisoning of the catalyst by chlorine in the form of chloroform on activity and selectivity was observed. Poisoning by chlorine led to a decrease in activity. Subsequent reactions of the 1-olefins, namely isomerisation and hydrogenation, were largely suppressed, at the same time the chain length of the products increasing as a consequence of the high temperatures required.
