    摘要： The invention concerns steps in a process for the synthesis of at least one alkyl tertiobutyl ether, preferably respectively MTBE or ETBE, from at least one alcohol and from isobutene, each synthesized at least partially from natural gas. The alcohol, preferably methanol or ethanol respectively, is synthesized at least partially from synthesis gas, a portion of said synthesis gas being prepared in a natural gas steam prereforming zone. The isobutene is synthesized in a series of processes which includes direct transformation of natural gas to ethylene, known as oxidative coupling of methane (OCM), dimerisation of ethylene to normal butene, isomerisation of n-butene to isobutene, and the separation units associated therewith.

    摘要： Process for producing olefins from natural gas, the natural gas (2) is mainly fractionated (1) into methane (3) and higher hydrocarbons (4), the latter being then mainly fractionated (17, 20) into propane (9) and ethane (7). The methane (3), admixed with oxygen (6), passes through an oxidation reactor (5), receives the ethane (7) and the obtained mixture passes through a pyrolysis reactor (8). The effluent coming out of reactor (8) receives the propane (9) and the obtained mixture passes through a pyrolysis reactor (10). A hydrocarbon flow comprising olefins (12), more particularly ethylene and propene, is recovered.

    摘要： A process for the synthesis of essentially linear saturated C.sub.5.sup.+ hydrocarbons from a gas phase comprising synthesis gas is described. The process comprises circulation of an inert liquid phase and said gas phase in a reaction zone, in which the reaction zone is provided with at least one means for introducing gas and liquid phases, and at least one means for extracting the hydrocarbon phase formed by the Fischer-Tropsch reaction, and characterized in that the reaction zone comprises at least one mixing means. Preferably, at least one mixing means is a static mixer. An apparatus for carrying out the described process is also described.
