A process for converting one or more C3-C12 oxygenates

摘要

A process for converting one or more C3-C12 oxygenates comprising: 1) contacting a feed comprising one or more C3-C12 oxygenates with a source of hydrogen in the presence of a sulphided hydrogenation catalyst to produce a partially hydrogenated effluent; 2) contacting at least part of the partially hydrogenated effluent with a source of hydrogen at a hydrogen partial pressure of at least 0.1 Mega Pascal in the presence of a sulphided carbon-carbon coupling catalyst to produce a conversion product; 3) optionally contacting at least part of the conversion product with a source of hydrogen in the presence of a sulphided hydrotreating catalyst and/or a sulphided hydroisomerization catalyst to produce a hydrotreated and/or hydroisomerized conversion product; and 4) optionally purifying the conversion product, optionally hydrotreated and/or hydroisomerized, conversion product to obtain a final product, wherein the carbon-carbon coupling catalyst comprises equal to or more than 60 wt% of a zeolite and in the range from equal to or more than 0.1 wt% to equal to or less than 10 wt% of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.
