Abstract: The present invention relates to a thermally integrated multi-zone process for conversion of alkanes to their corresponding alkenes, involving endothermically converting an alkane to its corresponding alkene by soft oxidant conversion in an endothermic reaction zone, in the presence of a weak oxidant, a suitable catalyst, and heat, to produce an intermediate product gas comprising the corresponding alkene and hydrogen. The weak oxidant may be, for example, carbon dioxide. The hydrogen is then removed from the intermediate product gas by contacting the intermediate product gas, in an exothermic reaction zone, with different second catalyst, and oxygen, to combust the hydrogen and produce a heated product stream comprising the corresponding alkene, water and heat. Heat is recovered from the heated product stream and recycled back to the endothermic reaction zone, while the resulting cooled product stream comprising the corresponding alkene may be subjected to further reaction and/or processing.

Abstract: The present invention relates to an integrated process for producing unsaturated carboxylic acids from the corresponding C2-C4 alkane. The process begins with integrated catalytic reactions comprising endothermic soft oxidant conversion (SOC) and exothermic selective hydrogen combustion (SHC) which cumulatively convert a C2-C4 alkane to its corresponding C2-C4 alkene in a product stream substantially free of hydrogen. Heat from the exothermic selective hydrogen combustion reaction zone is recovered and recycled back upstream to the endothermic soft oxidant conversion reaction zone. The hydrogen-free alkene products of the thermally integrated SOC/SHC reactions are then provided to a catalytic vapor phase partial oxidation process for conversion of the alkene to the corresponding unsaturated carboxylic acid or nitrile. Unreacted alkene and carbon dioxide are recovered from the oxidation product stream and recycled back to the thermally integrated soft oxidant conversion reactions.

Abstract: A process for the conversion of propane to propene is disclosed wherein a silica chromium catalyst composition is contacted with a propane feed stream and a carbon dioxide. The silica chromium catalyst composition is further disclosed wherein the composition, optionally, includes a promoter component.

Abstract: The present invention relates to an integrated multi-zone process for conversion of alkanes to their corresponding alkenes, involving exothermically converting a portion of an alkane to its corresponding alkene by oxidative dehydrogenation in an exothermic reaction zone, in the presence of oxygen and a suitable catalyst, and then feeding the products of the exothermic reaction zone to an endothermic reaction zone wherein at least a portion of the remaining unconverted alkane is endothermically dehydrogenated, in the presence of carbon dioxide and an other suitable catalyst.

Abstract: Operating conditions for generating hydrogen by the water-gas shift reaction have been found which reduce the aging of Pt—bimetallic water-gas shift catalysts. The process parameters provide a stable operation in residential fuel processors and in hydrogen generators for on-site hydrogen generation.
