Abstract: This invention comprises a method for converting natural gas to a normally liquid carbon containing compound, such as methanol and/or dimethyl ether and/or to gasoline grade liquid hydrocarbons and/or olefins. The method of this invention eliminates the need for steam reforming and/or adiabatic reforming with essentially pure oxygen of the natural gas to a synthesis gas. In accordance with the process of this invention, a synthesis gas may be produced at an operating pressure suitable for conversion thereof to methanol and/or dimethyl ether without the need for synthesis gas recompression. Further, the vent or bleed gas from the overheads after conversion to the crude product methanol/DME and/or its conversion to gasoline grade liquid hydrocarbons, generally has a BTU capacity required to serve as a fuel gas for supplying the energy needed for operation of a gas turbine which powers the gas compression equipment requirements by which the process of this invention may be practiced.

Abstract: In producing methanol by the reaction of carbon monoxide and hydrogen, a starting gas deficient in hydrogen, e.g. as produced by coal gasification, is mixed with a hydrogen rich gas and fed to a synthesis loop where it is mixed with unreacted gas from the synthesis stage. A part stream of gas is taken from the loop. Either that part stream, or the gas in the loop prior to synthesis, is subjected to the catalytic shift reaction with steam. Carbon dioxide is removed from the gas taken from the loop to form the hydrogen rich stream.

Abstract: A process has been discovered for the conversion of C.sub.5 -C.sub.7 olefinic hydrocarbons, such as those contained in FCC light naphtha, to iso-butene-rich and isoamylene-rich streams in an integrated process for the production of MTBE and TAME. The process involves the initial separation of the isoamylene-rich C.sub.5 -fraction of the feedstream which is converted to TAME. The C.sub.6 -C.sub.7 fraction plus unreacted C.sub.5 's are converted by olefin interconversion with medium pore zeolite catalyst into an isobutylene and isoamylene-rich stream which is then used as feedstream for etherification to MTBE and TAME.

Abstract: Peroxides such as di-tert-butyl peroxide, present in a methyl-tert-butyl ether recycle stream, may be removed by bringing the recycle stream into contact with an acid treated clay. The peroxides are decomposed to tert-butyl alcohol (main product) plus minor amounts of acetone and methanol. Since the recycle stream consists mainly of tert-butyl alcohol and methanol, methyl-tert-butyl ether is also formed in significant quantities. Isobutylene is also formed by dehydration of the tert-butyl alcohol.
