ABSTRACT:

Three runs were made with a commercial fused iron catalyst with objectives to study the effects of catalyst reduction procedure, particle size and process conditions on fixed bed reactor performance (activity and product selectivity). The catalyst activity increases as the space velocity of H sub 2 during the reduction increases or as the catalyst particle size decreases. An uncalcined precipitated iron catalyst (100 Fe/1 Cu/0.2 K on weight basis) was evaluated in a fixed bed reactor.  Initially, it showed an activity more than twice of the fused iron catalyst, but it deactivated after about 30 hours on stream. The work on catalyst synthesis and characterization of the precipitated iron catalysts has continued. 25 precipitated iron catalysts (Fe/Cu, Fe/K and Fe/Cu/K) have been prepared. Temperature programmed reduction has revealed that the iron reduction is facilitated in the presence of copper. Also, unpromoted iron and potassium promoted iron (containing 1 part K per 100 parts Fe) were examined using Fourier Transform Infrared Spectroscopy. 9 refs., 19 figs., 8 tabs.
