Patent number: 9453165Abstract: A process for converting a reactant composition comprising H2 and CO to a product comprising at least one aliphatic hydrocarbon having at least about 5 carbon atoms comprises: flowing the reactant composition through a microchannel reactor in contact with a Fischer-Tropsch catalyst to convert the reactant composition to the product, the microchannel reactor comprising a plurality of process microchannels containing the catalyst; transferring heat from the process microchannels to a heat exchanger; and removing the product from the microchannel reactor; the process producing at least about 0.5 gram of aliphatic hydrocarbon having at least about 5 carbon atoms per gram of catalyst per hour; the selectivity to methane in the product being less than about 25%. A supported catalyst comprises Co, and a microchannel reactor comprises at least one process microchannel and at least one adjacent heat exchange zone.Type: GrantFiled: April 30, 2015Date of Patent: September 27, 2016Assignee: Velocys, Inc.Inventors: Yong Wang, Anna Lee Tonkovich, Terry Mazanec, Francis P. Daly, Dave VanderWiel, Jianli Hu, Chunshe Cao, Charles Kibby, Xiaohong Li, Michael D. Briscoe, Nathan Gano, Ya-Huei Chin
