Bartholomew, C. H.

Significant progress was made in several task areas, but especially in the investigations of high pressure kinetics and deactivation by sulfur poisoning. Seventeen new catalysts were prepared for use in kinetic studies and long term tests. A number of catalysts were characterized using H/sub 2/ and CO adsorption and transmission electron microscopy. Activity tests were conducted for a borohydride reduced catalyst and samples of crushed and uncrushed monolithic nickel catalyst. Extensive kinetic experiments were performed on two monolithic nickel catalysts over a range of temperatures and pressures from which kinetic parameters and a rate expression were obtained. Long term experiments of H/sub 2/S poisoning during reaction were also conducted and the data were fitted to a Levenspiel deactivation kinetics model.
