摘要:
There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons including C.sub.5 + liquid hydrocarbons are produced. The catalyst used in this reaction may be a ZSM-5 catalyst. The process involves the use of an initial cofeed, such as propane, in admixture with the methane and oxygen to induce the formation of liquid hydrocarbons. As the reaction progresses, the flow of cofeed is shut off, and liquid hydrocarbons continue to be produced.

摘要:
A mixture of organic compounds comprising a major amount of liquid hydrocarbons, mostly aromatic, is formed by the direct partial oxidation of methane in the presence of a ZSM-5 catalyst. The reaction conditions are substantially the same as those required for the direct homogeneous partial oxidation to methanol. However, liquid hydrocarbon formation depends on the presence of a small amount of an impurity such as propane or propylene in the feed; in the absence of such, only methanol is formed. With such modifier present, controls of reaction parameters, e.g., temperature, permits synthesis of both methanol and liquid hydrocarbons in desired proportions. Properly processed natural gas can serve to provide methane and at least part of the reaction modifier.

A marked improvement in yield, in selectivity or in both is obtained in the synthesis of methanol by the homogeneous direct partial oxidation of natural gas or other source of methane when the reactor space is filled with inert, refractory inorganic particles.
摘要:
There is provided a process for converting methane to hydrocarbons having at least two carbon atoms (i.e. higher hydrocarbons). The process involves oxidizing methane with a metal sulfide oxidizing agent. After this conversion of methane, the reduced metal sulfide may be regenerated by oxidation of the reduced metal sulfide.
