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 C3-C12 oxygenates with hydrogen in the presence of a sulphided hydrogenation catalyst to produce a partially hydrogenated effluent;

2) contacting the partially hydrogenated effluent with hydrogen at a hydrogen partial pressure of at least 0.1 MegaPascal 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 hydrogen in the presence of a sulphided hydrotreating catalyst and/or a sulphided hydroisomerization catalyst to produce a 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 at least 60 wt % of a zeolite and in the range from 0.1 wt % to 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.

1. 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 MegaPascal 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, 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.
