  • Patent number: 9556092
    Abstract: A method includes a step of supplying a first heated hydrocarbon-containing gas stream to a reactor. An oxygen-containing gas stream is separately supplied to the reactor to partially oxidize the hydrocarbon-containing gas stream. The oxygen-containing gas is optionally prepared by passing air through one or more membranes to increase the oxygen content. One or more of the desired liquid oxygenated hydrocarbons are condensed and/or separated from the resulting product stream. Non-hydrocarbon gases are selectively removed from the product stream to enrich the gaseous hydrocarbon fraction using a scrubber and/or a membrane. The remaining gaseous hydrocarbon products from the product stream are mixed with a fresh hydrocarbon-containing gas stream after one cycle of the reaction. Characteristically, the process uses at least one membrane to increase oxygen content of the oxygen containing gas and/or to remove non-hydrocarbon gases from the product stream as set forth above.
