| 摘要 |
The invention relates to method of isomerizing dehydration of a primary alcohol substituted in position 2 by an alkyl group wherein the alcohol is heated to reaction temperature by indirect heat exchange then vaporized by mixing with a diluent effluent, where said diluted and vaporized alcohol is dehydrated in at least one dehydration reactor operating in the gas phase at an input temperature between 250°C and 375°C, a pressure between 0.2 MPa and 1 MPa and a PPH between 1 and 18 h-1, in the presence of a catalyst comprising a zeolite comprising at least one series of channels whose opening is defined by a ring of 8 oxygen atoms (8MR) and a binder, wherein said catalyst is coked in-situ or ex-situ beforehand, such as to produce a dehydration effluent, where the latter is treated and separated into a diluent effluent, an olefin effluent and a heavy-hydrocarbon effluent. |
