Title
Effective control of carbon number distribution during Fischer–Tropsch synthesis over supported cobalt catalyst
Abstract

Effective control of carbon number distribution in FTS has been demonstrated with co-fed 1-olefins in a trickle bed reactor. Addition of 1-octene or 1-dodecene in the n-paraffin solvent could greatly enhance the selectivity of heavy wax and increase the middle distillate to a certain extent directly from syngas, with a marked increase in CO conversion while suppressing the formation of lighter hydrocarbon products compared to the conventional FTS. In the case of co-fed 1-dodecene, the disproportionate reaction was obviously observable, which resulted in a symmetrical product distribution and gave a much higher selectivity in the middle distillate.
