Howard, Jr, W F

This long-term (7.5 year) project has focussed on supported-metal catalysts commonly used in synthesis gas (CO + H/sub 2/) conversions. These catalysts are very susceptible to sulfur poisoning, and the causes of sulfur deactivation were determined employing surface science and reactor engineering techniques. Transition metal catalysts were synthesized and studied by electron, x-ray, and infrared spectroscopies, and flow reactor systems, with the goal of finding high activity/selectivity systems with sulfur-resistant properties; this effort met with moderate success, but a more worthwhile approach proved to involve the regeneration of working catalysts. Most recently, this research has been concerned with carbon deposition and deactivation of common industrial Co and Ni methanation catalysts, and much insight into the catalytic CO/H/sub 2/ conversion process has been attained.
