    摘要: The present disclosure relates to a system and a process for producing biofuel. The system comprises at least one feed tank; a low pressure pump; a high pressure pump; a first heat exchanger; a second heat exchanger; a reaction vessel; a precipitation vessel; a first pressure let-down station; a third heat exchanger; a second pressure let-down station; a gas-liquid separator; and a biofuel separator. The process comprises pressurizing and heating a feed, followed by reforming the pressurized and heated feed to obtain a slurry. The solids are separated from the slurry by precipitation to obtain a mixture comprising biofuel and the non-reformed feed. The mixture is then cooled and de-pressurized, followed by separation of gases and the non-reformed feed to obtain the biofuel. The system and process of the present disclosure can be used to produce biofuel from diverse, easily available and inexpensive starting material.

    摘要: The present invention provides a process for producing liquid hydrocarbon products from a solid biomass feedstock, said process comprising the steps of: a) providing in a first hydropyrolysis reactor vessel a first hydropyrolysis catalyst composition; b) contacting the solid biomass feedstock with said first hydropyrolysis catalyst composition and molecular hydrogen in said first hydropyrolysis reactor vessel to produce a product stream comprising partially deoxygenated hydropyrolysis product, H2O, H2, CO2, CO, C1-C3 gases, char and catalyst fines; c) removing said char and catalyst fines from said product stream; d) hydroconverting said partially deoxygenated hydropyrolysis product in a hydroconversion reactor vessel in the presence of one or more hydroconversion catalyst and of the H2O, CO2, CO, H2, and C1-C3 gas generated in step a), to produce a vapor phase product comprising substantially fully deoxygenated hydrocarbon product, H2O, CO, CO2, and C1-C3 gases.
