A multistage catalytic partial oxidation (CPO) process for oxidizing a hydrocarbon feedstream comprising C -C hydrocarbons, with an oxygen-containing feedstream to produce a product comprising CO and H , also known as synthesis gas or syngas. The process employs a CPO catalyst, and controlled process features, including: (A) the total oxygen requirement for the process is introduced incrementally, in more than one reaction stage, using an oxygen-containing feedstream at more than one feed point in the process, each stage including a catalyst; (B) the oxygen-containing feedstream, hydrocarbon feedstream and, in reaction stages after the first of said multiple stages, the intermediate product produced in the prior stage, are mixed for a period of time, after they are brought into contact with one another, of less than about 1 millisecond to form a substantially uniform mixture, wherein the mixture is then contacted with the catalyst; (C) the oxygen-containing feedstream and the hydrocarbon feedstream are preheated prior to entry into the first stage, to a temperature of from about 450Â C. to less than about 1,000Â C. ; and (D) the mixture temperature of the product in each stage following the first stage is from greater than about 600Â C.

Linear alpha olefins having from four to twenty carbon atoms and low amounts of oxygenates are synthesized, by producing a synthesis gas containing H and CO from natural gas and passing it over a non-shifting cobalt catalyst at reaction conditions of temperature, % CO conversion, and gas feed H :CO mole ratio land water vapor pressure, effective for the mathematical expression 200-0. 6T+0. 03P -0. 6X -8(H :CO) to have a numerical value greater than or equal to 50. This process can be integrated into a conventional Fischer-Tropsch hydrocarbon synthesis process producing fuels and lubricant oils.

This invention is directed to a heat exchanged membrane reactor for electric power generation. More specifically, the invention comprises a membrane reactor system that employs catalytic or thermal steam reforming and a water gas shift reaction on one side of the membrane, and hydrogen combustion on the other side of the membrane. Heat of combustion is exchanged through the membrane to heat the hydrocarbon fuel and provide heat for the reforming reaction. In one embodiment, the hydrogen is combusted with compressed air to power a turbine to produce electricity. A carbon dioxide product stream is produced in inherently separated form and at pressure to facilitate injection of the CO into a well for the purpose of sequestering carbon from the earths atmosphere.

The invention provides a method for producing liquid hydrocarbons by first generating in a pressure swing reformer a synthesis gas stream having a mole ratio of H:CO greater than 2:1. Then, a portion of the hydrogen is separated to produce a synthesis gas stream having a mole ratio of H:CO of about 2:1 which steam is then introduced into a hydrocarbon synthesis reactor for conversion to liquid products.

A process for producing methanol is described in which a hydrocarbon is steam reformed in a reforming zone, and during the reforming stage, of a cyclic steam reformer having a reforming stage and a regeneration stage, the steam reforming being conducted under conditions effective to produce a first effluent stream containing synthesis gas. Fuel and an oxygen-containing gas are combusted in the regeneration stage of the reformer so as to reheat the reforming zone to a temperature sufficient for the reforming stage and generate a flue gas. At least part of the first effluent stream is contacted with a methanol synthesis catalyst under conditions effective to convert synthesis gas to methanol and form a methanol-containing stream and a tail gas stream comprising unreacted carbon monoxide and hydrogen. At least part of the tail gas stream is recycled as fuel for the regeneration stage of the cyclic steam reformer.
