Patent number: 10669491Abstract: Methods are provided for making base metal catalysts with improved activity. After forming catalyst particles based on a support comprising a zeolitic molecular sieve, the catalyst particles can be impregnated with a solution comprising a) metal salts (or other precursors) for a plurality of base metals and b) an organic dispersion agent comprising 2 to 10 carbons. The impregnated support particles can be dried to form a base metal catalyst, and then optionally sulfided to form a sulfided base metal catalyst. The resulting (sulfided) base metal catalyst can have improved activity for cloud point reduction and/or for improved activity for heteroatom removal, relative to a base metal dewaxing catalyst prepared without the use of a dispersion agent.Type: GrantFiled: November 30, 2016Date of Patent: June 2, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Stephen J. McCarthy, Chuansheng Bai, Wenyih Frank Lai, Paul Podsiadlo, William W. Lonergan

Publication number: 20180362860Abstract: Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions.Type: ApplicationFiled: December 19, 2016Publication date: December 20, 2018Inventors: Stephen J. McCarthy, Paul Podsiadlo, Chuansheng Bai, Richard C. Dougherty, Wenyih F. Lai, William W. Lonergan
