ABSTRACT:

The medium-level sulfur-treated (50% monolayer sulfur coverage) iron and cobalt catalysts were tested for FTS activity, with the clean fused iron catalyst tested as a comparative standard for the fixed-bed reactor operated at high pressure (2 MPA). Of the four improved catalysts chosen for evaluation at high pressure FTS synthesis, the medium-level sulfur-treated fused iron catalyst seems most promising, with a 50% reduction in methane yield, a narrower product distribution, and a threefold increase in olefin selectivity. The sulfur-treated catalyst exhibited behavior at 2 MPa similar to the 0.1 MPa synthesis run; however, the olefin selectivity decreased with increasing temperature or pressure.  5 figs., 2 tabs.
