Role of transition metal sulfides in hydrotreatment. Part I. Iron sulfide as catalyst
Two pairs of catalysts were prepared for the study of iron sulfide as a catalyst in the hydrotreatment of heavy crude oil. The catalysts were prepared by impregnating silica and ..gamma..-alumina with an amount of Fe twice the pore volume in one case and four times the pore volume in the other case. Chemical composition, pore volume and pore size distribution were evaluated for the oxidic form of the catalysts, and catalytic activity was measured in a bench scale reactor unit. The hydrometallization (HDM) and hydrodesulfurization (HDS) activity of the catalysts was determined by measuring the vanadium and sulfur contents, respectively, in the feed products after 90-min reaction time. A requirement of a physicochemical affinity between sulfides of iron and the metals in the feed is postulated as a first approach to explain the HDM activity of iron sulfides, and the need of a macroporous structure of the catalyst as previously reported is reaffirmed.
