Publication number: 20230241586Abstract: Tandem catalysts for the dehydrogenation of alkanes and/or alcohols in tandem with selective hydrogen combustion are provided. Also provided are methods of making the catalysts and methods of using the catalysis for the dehydrogenation of alkanes and/or alcohols. The catalysts include a support having a surface, dehydrogenation catalysts particles dispersed on the surface of the support, and a porous selective hydrogen combustion catalyst overcoat on the dehydration catalyst particles. The catalysts couple dehydrogenation with selective hydrogen combustion in a sequence of reactions occurring in tandem to shift the equilibrium of the dehydrogenation towards higher conversion.Type: ApplicationFiled: July 29, 2021Publication date: August 3, 2023Inventors: Justin M.

Patent number: 9815753Abstract: A method is provided comprising exposing a supported heterogeneous metathesis catalyst to an olefin compound for an activation time at an activation temperature; exposing the activated supported heterogeneous metathesis catalyst to a reactant capable of undergoing a metathesis reaction for a reaction time at a reaction temperature to produce metathesis products; and exposing the deactivated supported heterogeneous metathesis catalyst to a regenerating compound for a regeneration time at a regeneration temperature. The activity of the regenerated supported heterogeneous metathesis catalyst may be substantially the same or greater than the activity of the activated supported heterogeneous metathesis catalyst prior to deactivation. The activation temperature may be greater than the reaction temperature. The regenerating compound may be a second olefin compound or an inert gas.Type: GrantFiled: September 14, 2015Date of Patent: November 14, 2017Assignee: Northwestern UniversityInventors: Kunlun Ding, Peter C. Stair

Patent number: 8815766Abstract: Embodiments include metal (102) containing composites (100) and methods of forming metal containing composites. A metal containing composite can be formed by contacting an oxide support surface (104) with coordination compounds having metal atoms for a first predetermined time, where the metal atoms of the coordination compounds deposit on the oxide support surface; contacting the oxide support surface with a first reagent for a second predetermined time; and contacting the first reagent with a second reagent for a third predetermined time, where the first reagent and the second reagent react to form another layer of the oxide support surface.Type: GrantFiled: June 11, 2010Date of Patent: August 26, 2014Assignee: Northwestern UniversityInventors: Junling Lu, Peter C. Stair

Patent number: 8318248Abstract: Methods for the selective deposition of materials within a porous substrate. The methods use the passivating effects of masking precursors applied to the porous substrate. A portion of a pore surface within the substrate is masked by exposing the substrate to one or more masking precursors. The depth of the pore surface that is masked is controllable by regulating the exposure of the substrate to the masking precursor. Application of the masking precursor prevents adsorption of one or more subsequently applied metal precursors about a portion of the pore surface coated by the masking precursor. Less than an entirety of the unmasked pore surface is coated by the metal precursor, forming a metal stripe on a portion of the pore surface. The depth of the metal stripe is controllable by regulating exposure of the porous substrate to the metal precursor. Subsequent exposure of the substrate to a saturating water application oxidizes the deposited precursors.Type: GrantFiled: June 4, 2009Date of Patent: November 27, 2012Assignee: Uchicago Argonne, LLCInventors: Jeffrey W. Elam, Joseph A. Libera, Michael J. Pellin, Peter C. Stair
