Abstract: A process and apparatus for converting an alkane to an olefin. In one embodiment, the process involves oxidative coupling of an alkane, e.g., methane, with an oxidant, such as air, to produce an olefin having twice the number of carbon atoms as the alkane, e.g., ethylene. In another embodiment, the process involves oxidative dehydrogenation of an alkane, e.g., ethane, with an oxidant to form an olefin having the same number of carbon atoms as the alkane, e.g., ethylene. The process involves passing a flow of the oxidant from a first flow passage through a porous medium; diffusing a flow of the alkane from a second flow passage into the porous medium; and contacting the reactant alkane and the oxidant in the presence of a catalyst within the porous medium to produce the olefin.

Abstract: A chemical reactor for use in a chemical process wherein a reactant and/or a target product is prone to produce undesirable byproducts through secondary reactions. The reactor is configured with a first flow passage for passing a flow of an overly reactive reactant; a permeable first wall for controlled flow of the overly reactive reactant into a second flow passage providing a flow of a second reactant; a permeable second wall having a catalyst supported on an inner surface thereof for catalyzing reaction of the reactants flowing in the second flow passage; the permeable second wall passing through a flow containing the target product; and a non-permeable third wall defining a third flow passage for exiting the product mixture. The reactor can be employed in selective oxidation, oxidative dehydrogenation, and alkylation processes to reduce the formation of byproducts.

Abstract: A stabilized composition comprising a liquid hydrocarbon fuel, such as JP-8, and a fuel additive, wherein the fuel additive comprises a graphitic carbon compound functionalized with a plurality of alkyl groups, wherein at least one alkyl group at each site of alkyl functionalization on the graphitic carbon compound has 8 or more carbon atoms, for example, poly(octadecyl)-graphene oxide. A method of increasing the energy density of a liquid hydrocarbon fuel involving adding to the fuel one or more alkyl-functionalized graphitic carbon compounds. The stabilized composition is useful for enhancing the properties of combustion processes, including energy density, thrust, flame speed, or a combination thereof, without introducing undesirable combustion effects, emissions, or combustion signature.

Abstract: A bimetallic catalyst composition containing a mesh substrate having supported thereon an alumina washcoat on which are impregnated bimetallic particles of rhodium and ruthenium in specified amounts. A process for the catalytic partial oxidation of a hydrocarbon, such as methane or natural gas, involving contacting the hydrocarbon with an oxidant in the presence of the aforementioned bimetallic catalyst under reaction conditions sufficient to produce synthesis gas, that is, to a mixture of hydrogen and carbon monoxide.

Abstract: A process of removing at least one metal contaminant, such as copper, from a fluid hydrocarbon, for example, crude oil or a liquid hydrocarbon fuel, such as an aviation fuel. The process involves contacting the metal-contaminated fluid hydrocarbon with a sorbent selected from graphene oxide or a functionalized graphene oxide. The process removes greater than 99 percent of the metal contaminant without reducing concentrations of advantageous additives, such as, antioxidants, icing inhibitors and corrosion inhibitors. Also disclosed are a purified fluid hydrocarbon composition and a metal contaminant filter system.
