Abstract: A process for converting natural gas to liquid hydrocarbons comprising heating the gas through a selected range of temperature for sufficient time and/or combustion of the gas at a sufficient temperature and under suitable conditions for a reaction time sufficient to convert a portion of the gas stream to reactive hydrocarbon products, primarily ethylene or acetylene. The gas containing acetylene may be separated such that acetylene is converted to ethylene. The ethylene product(s) may be reacted in the presence of an acidic catalyst to produce a liquid, a portion of which will be predominantly naphtha or gasoline. A portion of the incoming natural gas or hydrogen produced in the process may be used to heat the remainder of the natural gas to the selected range of temperature. Reactive gas components are used in a catalytic liquefaction step and/or for alternate chemical processing.

Abstract: A method for the absorption of alkynes and diolefins from an ethylene or propylene containing stream with conversion to alkenes by catalytic hydrogenation in a solvent over a fixed bed comprising a supported catalyst.

Abstract: A process and catalyst for the liquid phase selective hydrogenation of alkynes to alkenes with high selectivity to alkenes relative to alkanes, high alkyne conversion, and sustained catalytic activity comprising a reactant comprising an alkyne and a non-hydrocarbon solvent/absorbent, contacting the reactant stream with a hydrogen-containing stream in the presence of a supported, promoted, Group VIII catalyst, removing the solvent/absorbent, and recovering the alkene product.

Abstract: A process for converting natural gas to reactive gaseous products, comprising heating the gas through a selected range of temperature for sufficient time, or combusting a portion of the gas at a sufficient temperature and under suitable conditions for a reaction time sufficient to convert a portion of the gas stream to reactive hydrocarbon products, primarily ethylene or acetylene. The gas containing acetylene may be separated such that acetylene is converted to ethylene. A portion of the incoming natural gas or hydrogen produced in the process may be used to heat the remainder of the natural gas to the selected range of temperature. Unrecovered gaseous products resulting from the reactions may be used to provide heat to the process by which reactive gas components are produced. Recovered gaseous products, together or individually, may be reserved for subsequent use or storage.

Abstract: A composition and method for preparation of a catalyst for the liquid phase selective hydrogenation of alkynes to alkenes with high selectivity to alkenes relative to alkanes, high alkyne conversion, and sustained catalytic activity comprising a Group VIII metal and a Group IB, Group IIB, Group IIIA, and/or Group VIIB promoter on a particulate support.
