Abstract: Catalytic material having catalysts supported by hibonite-type supports are provided. The catalytic materials include a first catalytic material comprising an oxidative coupling methane catalyst for oxidative coupling of methane (OCM) and a second selective oxidation catalytic material comprising a selective oxidation catalyst that preferentially oxidizes hydrogen and carbon monoxide over methane. Systems comprising the first and second catalytic materials for performing an OCM reaction using a low temperature feedstock gas mixture and methods of using the same to prepare C2+ compounds are also provided.

Abstract: Apparatus and processes herein provide for converting hydrocarbon feeds to light olefins and other hydrocarbons. The processes and apparatus include a conventional riser reactor in combination with a mixed flow (e.g., including both counter-current and co-current catalyst flows) fluidized bed reactor designed for maximizing light olefins production. The effluents from the riser reactor and mixed flow reactor are processed in a catalyst disengagement vessel, and the catalysts used in each reactor may be regenerated in a common catalyst regeneration vessel. Further, integration of the two-reactor scheme with a catalyst cooler provides a refinery the flexibility of switching the operation between the two-reactor flow scheme, a catalyst cooler only flow scheme, or using both simultaneously.

Abstract: A cascade reactor scheme with acid and hydrocarbon flowing in reverse directions. The systems and processes for alkylation of olefins herein may include providing a first olefin to a first alkylation zone, and a second olefin to a second alkylation zone. Isoparaffin may be provided to the first alkylation zone. The isoparaffin and first olefin may be contacted with a partially spent sulfuric acid in the first alkylation zone to form a spent acid phase and a first hydrocarbon phase including alkylate and unreacted isoparaffin. The first hydrocarbon phase and second olefin may be contacted with a sulfuric acid feed in the second alkylation zone to form a second hydrocarbon phase, also including alkylate and unreacted isoparaffin, and the partially spent sulfuric acid that is fed to the first alkylation zone. Further, the second hydrocarbon phase may be separated, recovering an isoparaffin fraction and an alkylate product fraction.

Abstract: A method of performing an oxidative coupling of methane (OCM) reaction to produce C2+ compounds using a low temperature gas mixture feed is provided. The method includes introducing a gas mixture feed containing methane, oxygen, hydrogen, and carbon monoxide at a temperature of less than or equal to 300° C. to an inlet of an OCM reactor, which contains a combustion catalyst and an OCM catalyst. At least a portion of the gas mixture feed is combusted using the combustion catalyst to generate a heated gas mixture having a temperature of at least 450° C. The heated gas mixture contacts the OCM catalyst to initiate an OCM reaction and produce an OCM effluent that includes C2+ compounds. A system for performing an OCM reaction using a low temperature feedstock gas mixture is also provided.
