ABSTRACT:

The aim of the work is to carry out a simulation of the reactor operation of a selected model reaction in variously dimensioned reaction pipes, in order to obtain information on how the maximum permissible pipe diameter should be selected, by which a reasonable product selectivity is obtained.  The Fischer-Tropsch synthesis is selected as the model reaction, as on the one hand one is interested in increasing its capacity and on the other hand because of numerous investigations in the past and in the present, which have published sufficient parameters for a simulation. The criterion for selectivity is to be the formation of methane, which adversely affects the product quality at high excess temperatures in the reactor. The ARGE fixed bed reactor is to be used as the model reactor, as operated in the SASOL plant in South Africa. (ERA citation 11:040088)
