Patent number: 7632320Abstract: The present invention is a chemical reactor and method for catalytic chemical reactions having gas phase reactants. The chemical reactor has reactor microchannels for flow of at least one reactant and at least one product, and a catalyst material wherein the at least one reactant contacts the catalyst material and reacts to form the at least one product. The improvement, according to the present invention is: the catalyst material is on a porous material having a porosity that resists bulk flow therethrough and permits molecular diffusion therein. The porous material further has a length, a width and a thickness, the porous material defining at least a portion of one wall of a bulk flow path through which the at least one reactant passes.Type: GrantFiled: November 18, 2005Date of Patent: December 15, 2009Assignee: Battelle Memorial InstituteInventors: Anna Lee Y. Tonkovich, Yong Wang, Sean P. Fitzgerald, Jennifer L. Marco, Gary L. Roberts, David P. Vanderwiel, Robert S. Wegeng

Patent number: 7585899Abstract: The present invention includes a catalyst structure and method of making the catalyst structure for Fischer-Tropsch synthesis that both rely upon the catalyst structure having a first porous structure with a first pore surface area and a first pore size of at least about 0.1 ?m, preferably from about 10 ?m to about 300 ?m. A porous interfacial layer with a second pore surface area and a second pore size less than the first pore size is placed upon the first pore surface area. Finally, a Fischer-Tropsch catalyst selected from the group consisting of cobalt, ruthenium, iron and combinations thereof is placed upon the second pore surface area. Further improvement is achieved by using a microchannel reactor wherein the reaction chamber walls define a microchannel with the catalyst structure placed therein through which pass reactants. The walls may separate the reaction chamber from at least one cooling chamber. The present invention also includes a method of Fischer-Tropsch synthesis.Type: GrantFiled: February 27, 2006Date of Patent: September 8, 2009Assignee: Battelle Memorial InstituteInventors: Yong Wang, David P.
