Patent number: 6863803Abstract: A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content than the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at lease one Group VIII non-noble metal and at least two Group VIB metals.Type: GrantFiled: January 14, 2000Date of Patent: March 8, 2005Assignee: ExxonMobil Research and Engineering CompanyInventors: Kenneth Lloyd Riley, Darlene Schuette, Stuart Leon Soled, Sabato Miseo, William Lee Schuette

Patent number: 6755963Abstract: This invention provides a process for hydrotreating hydrocarbon resins, which process comprises contacting a feedstock comprising a hydrocarbon resin or rosin, under suitable hydrotreating conditions, with a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals and wherein the ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. The process according to the invention can achieve increased hydrocarbon resin productivity through increase in throughput volumes and effective catalyst lifetimes. The process of the invention is desirably practiced with a bulk catalyst consisting of only the combination of the metal species with the active metal components. The absence of carrier substrates largely removes the possibility of halogen accumulation on substrate surfaces that, in turn, can acidify metal catalysts such that additional, progressive cracking of the hydrocarbon resin molecules occurs.Type: GrantFiled: October 1, 2002Date of Patent: June 29, 2004Assignee: ExxonMobil Chemical Patents Inc.Inventors: Jerry L. Haluska, Kenneth Lloyd Riley
