Abstract
The invention relates to a continous process for converting carbonaceous material contained in at least two feedstocks into a liquid hydrocarbon product, said feedstocks including at least one feedstock of biomass and at least one feedstock of lignite and/or peat, 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; and separating a fraction comprising liquid hydrocarbon product and leaving a residual fraction.

69. A continous process for converting carbonaceous material contained in at least two feedstocks into a liquid hydrocarbon product, said feedstocks including at least one feedstock of biomass and at least one feedstock of lignite and/or peat, 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 5% by weight, the process comprising:
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., andmaintaining 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. andexpanding 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; and separating a fraction comprising liquid hydrocarbon product and leaving a residual fraction. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83)
