    Abstract: 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.

  • Patent number: 5113032
    Abstract: 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.
