ABSTRACT:
The invention concerns 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 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), dimerization of ethylene to normal butene, isomerization of n-butene to isobutene, and the separation units associated therewith.
