PROCESS AND APPARATUS FOR PRODUCING LIQUID HYDROCARBON

摘要

The invention relates to a continous process for converting carbonaceous material contained in one or more feedstocks into a liquid hydrocarbon product, said feedstocks including the carbonaceous material being in a feed mixture including one or more fluids, said fluids including water and further liquid organic compounds at least partly produced by the process in a concentration of at least 1% by weight, where the process comprises converting at least part of the carbonaceous material by pressurising the feed mixture to a pressure in the range 50-400 bar, heating the feed mixture to a temperature in the range 250- 500 °C, and maintaining said pressurized and heated feed mixture in the desired pressure and temperature ranges in a reaction zone for a predefined time; cooling the feed mixture to a temperature in the range 25-200 °C and expanding the feed mixture to a pressure in the range of 1-70 bar, thereby causing the carbonaceous material to be converted to a liquid hydrocarbon product; separating a fraction comprising liquid hydrocarbon product, and leaving a residual fraction; feeding said residual fraction into a bioreactor for the production of biomass such as algae and/or bacteria such as cyano bacteria.
