Patent number: 8455556Abstract: A process for the preparation of a packed bed comprising an iron enriched cobalt catalyst for use in a Fischer-Tropsch reaction, the process comprising the steps of: (a) providing a packed bed with one or more catalyst particles comprising metallic cobalt; (b) contacting a part of the catalyst particle(s) in the packed bed with an iron containing compound. The process is preferably conducted in situ which conveniently results in an iron containing cobalt catalyst with a higher C5+ selectivity. In certain preferred embodiments the concentration of iron increases towards the surface of the resulting catalyst particles whereas the cobalt concentration is constant which further increases the selectivity of the catalyst to producing C5+ hydrocarbons.Type: GrantFiled: July 12, 2007Date of Patent: June 4, 2013Assignee: Shell Oil CompanyInventors: Ralph Haswell, Carolus Matthias Anna Maria Mesters, Heiko Oosterbeek, Thomas Joris Remans, Marinus Johannes Reynhout

Patent number: 7811967Abstract: A method of preparing, preferably recycling, a catalyst support material is disclosed and is particularly applicable to recycling a titania support. The invention includes crushing the used catalyst support that is obtained by leaching catalytic components from a used supported catalyst and preferably combining it with new catalyst support in order to provide the required average particle size and ratio of crystal phases. The invention has a number of benefits including making use of used catalyst support materials which have been conventionally disposed of and also providing a method to more efficiently recycle the active component. Where the support is recycled for a similar application, less promoter may be required.Type: GrantFiled: December 21, 2005Date of Patent: October 12, 2010Assignee: Shell Oil CompanyInventors: Marinus Johannes Reynhout, Guy Lode Magda Maria Verbist
