Zusammenfassung: | The present invention provides a process for producing liquid hydrocarbon products from a biomass, biomass-containing and/or biomass-derived feedstock, said process comprising the steps of: a) contacting the feedstock with one or more hydropyrolysis catalyst compositions and molecular hydrogen in a hydropyrolysis reactor vessel at a temperature in the range of from 350 to 600°C and a pressure in the range of from 0.50 to 7.50MPa, to produce a product stream comprising hydropyrolysis product that is at least partially deoxygenated, H2O, H2, CO2, CO, C1 - C3 gases, char and catalyst fines; b) removing all or a portion of said char and catalyst fines from said product stream; c) hydroconverting said hydropyrolysis product in a hydroconversion reactor vessel in the presence of one or more hydroconversion catalyst compositions and of at least a portion of the H2O, CO2, CO, H2, and C1 - C3 gases generated in step a), to produce a vapour phase product comprising substantially fully deoxygenated hydrocarbon product, H2O, CO, CO2, and C1 C3 gases, wherein one or both of the hydropyrolysis catalyst composition and the hydroconversion catalyst composition is produced in a process comprising the steps of incorporating one or more metals selected from those of groups 6, 9, and 10 of the periodic table, into a shaped support; and incorporating one or more coordinating organic compounds into said shaped support, thus forming a catalyst precursor; and then either (i) treating the catalyst precursor in the presence of hydrogen and sulfiding it or (ii) calcining the catalyst precursor.
La présente invention concerne un procédé de production de produits hydrocarbonés liquides à partir d'une charge d'alimentation de biomasse, d'une charge d'alimentation contenant de la biomasse et/ou d'une charge d'alimentation dérivée de la biomasse, ledit procédé comprenant les étapes consistant à : a) mettre en contact la charge d'alimentation avec une ou plusieurs compositions de catalyseurs d'hydropyrolyse et de l'hydrogène moléculaire dans une cuve de réacteur d'hydropyrolyse à une température comprise entre 350 et 600 °C et à une pression comprise entre 0,50 et 7,50 MPa, pour produire un flux de produits comprenant un produit d'hydropyrolyse qui est au moins en partie désoxygéné, du H2O, du H2, du CO2, du CO, des gaz en C1-C3, un produit de carbonisation et des fines de catalyseur ; b) éliminer dudit flux de produits tout ou partie dudit produit de carbonisation et desdites fines de ca |
