Investigation of the Activity of Zonal Catalyst Beds for Hydrodesulfurization and Hydrodenitrogenation of a Coal-derived Liquid
Abstract
Two different catalysts, Ketjenfine-124 (Co-Mo-alumina) and HDN- 30 (Ni-Mo-alumina) were studied for hydrotreatment of Pamco Solvent (a coal-derived liquid) separately and in a zonal bed combination. Experiments were conducted at a pressure of 1500 psig and temperatures of 615�F (324�C) and 815�F (435�C). Data were obtained for liquid volume hourly space times in the range of 0.5 to 2.5 hours. Five experimental runs were conducted with run durations up to 120 hours.
