Patent number: 7410804Abstract: A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations. The main support is equipped with a flat support temporarily attached to its first surface. All samples are loaded simultaneously. A flat surface of each sample, where the flat surfaces are a common plane, is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support using at least one cover. The flat surfaces of the samples are in predefined locations and are all in a common plane.Type: GrantFiled: August 12, 2004Date of Patent: August 12, 2008Assignee: UOP LLCInventors: Rune Wendelbo, Duncan E.

Patent number: 7288411Abstract: A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.Type: GrantFiled: August 27, 2003Date of Patent: October 30, 2007Assignee: UOP LLCInventors: Duncan E. Akporiaye, Arne Karlsson, Ivar M. Dahl, Rune Wendelbo, Kurt M.
