![]() ![]() Other investigations of the first-stage operation included process variable and hydrodynamic studies. Methane + ethane yields ranged from 2 to 18 wt % of total hydrocarbons produced, with reactor-wax (those heavy hydrocarbons retained in the slurry reactor under reaction conditions) yields ranging from 3 to 85 wt %. ![]() Total hydrocarbon production as high as 815 g/gFe was achieved, which is substantially better than other results reported in the literature. Three Fischer-Tropsch catalysts of Fe/Cu/K/sub 2/CO/sub 3/ type were evaluated. The feasibility of this two-stage technology was successfully demonstrated in a newly designed and constructed bench-scale unit (BSU), consisting of a slurry bubble column reactor followed by a fixed-bed ZSM-5 reactor. An evaluation study was conducted on a novel two-stage slurry Fischer-Tropsch/ZSM-5 process for converting low H/sub 2//CO ratio synthesis gas, which can generally be obtained from highly efficient, advanced coal-gasification systems, into high quality gasoline. ![]()
