CONVERSION OF ORGANIC OXYGENATES TO HYDROCARBONS

摘要

In a process for the catalytic conversion of organic oxygenates to hydrocarbons, a feed comprising at least one organic oxygenate is contacted with a zeolite catalyst under conditions effective to produce a hydrocarbon product comprising aromatics, olefins and paraffins. At least a fraction of the hydrocarbon product containing C4+ hydrocarbons, including at least part of the olefins, is then contacted with hydrogen in the presence of a hydrogenation catalyst under conditions effective to saturate at least part of the olefins in the C4+-containing fraction and produce a hydrogenated effluent containing less than 1 wt % olefins. The hydrogenated effluent is useful as a diluent for heavy crude oils.

1. A process for the catalytic conversion of organic oxygenates to hydrocarbons, the process comprising:
(a) contacting a feed comprising at least one organic oxygenate with a zeolite catalyst under conditions effective to produce a hydrocarbon product comprising aromatics, paraffins, and olefins; and (b) contacting at least a fraction of the hydrocarbon product containing C4+ hydrocarbons, including at least part of the olefins, with hydrogen in the presence of a hydrogenation catalyst under conditions effective to decrease the olefin content of the C4+-containing fraction and to produce a hydrogenated effluent containing less than 1 wt % olefins.
