Title: Technology development for cobalt F-T catalysts. Quarterly technical progress report No. 8, July 1, 1994--September 30, 1994

Abstract

The objective of this project is to investigate the influence of various promoters, additives, and supports on minimizing the methane selectivity and increasing the water-gas shift (WGS) activity of cobalt (Co) Fischer-Tropsch (F-T) catalysts. The ultimate goal of this investigation is to identify and demonstrate a catalyst preparation procedure that will be scaled up for the reproducible synthesis of commercial quantities of supported Co catalysts with desired activity, selectivity, and lifetime for use in F-T synthesis in three-phase slurry bubble column reactors. Accomplishments for this quarter are: Four new catalysts were formulated and prepared during this period under both subtasks 1.2 and 1.3 and five more catalysts were prepared by Calsicat; The characterization of all the catalysts in order to determine their physical properties (BET surface area, pore volume, pore size diameter, particle size distribution), as well as the cobalt reducibility, extent of reduction, and dispersion) was continued; Seven new catalysts have been tested for their F-T synthesis performance; An investigation of the effect of pre-treatment (i.e. calcination in static air versus flowing air, direct reduction without prior calcination) of a selected number of catalysts upon their performance for F-T synthesis was continued during this period.
