Abstract
Official abstract text for this publication.
Methods, compositions, and articles of manufacture for alkane activation with single- or bi-metallic catalysts on crystalline mixed oxide supports.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for non-oxidative coupling of methane comprising: synthesizing a bimetallic catalyst on a SiO 2 support by: grafting cobalt or molybdenum on the SiO 2 support forming a grafted SiO 2 support; impregnating platinum on the grafted support, forming the bimetallic catalyst; exposing methane to the bimetallic catalyst; and converting methane to ethylene with an initial conversion of 8%. 2. The method of claim 1 , wherein the bimetallic catalyst has an initial selectivity in the conversion of methane to ethylene of at least 80%. 3. The method of claim 1 , wherein the conversion of methane is at a temperature of between 550° C. and 650° C. 4. The method of claim 1 , wherein the synthesizing further comprises, prior to impregnating, calcining the grafted SiO 2 support. 5. The method of claim 4 , wherein grafting comprises sequential grafting method. 6. The method of claim 5 , wherein sequential grafting comprises strong electrostatic adsorption. 7. The method of claim 6 , wherein the impregnating comprises incipient wetness impregnation.
