RECYCLABLE BUFFER FOR THE HYDROTHERMAL HYDROCATALYTIC TREATMENT OF BIOMASS |
摘要 |
A method of hydrothermal hydrocatalytic treating biomass is provided. Lignocellulosic biomass solids is provided to a hydrothermal digestion unit in the presence of a digestive solvent, at least one of ammonia or a source of ammonia, and a supported hydrogenolysis catalyst containing (a) sulfur, (b) Mo or W, and (c) Co, Ni or mixture thereof, incorporated into a suitable support. The lignocellulosic biomass solids and digestive solvent are heated in the presence of hydrogen, supported hydrogenolysis catalyst and the at least one of ammonia or a source of ammonia forming a product solution containing plurality of oxygenated hydrocarbons and ammonia. At least a portion of ammonia is separated and recycled to the hydrothermal digestion unit. |

1. A method comprising: (i) providing lignocellulosic biomass solids in a hydrothermal digestion unit in the presence of a digestive solvent, at least one of ammonia or a source of ammonia, and a supported hydrogenolysis catalyst containing (a) sulfur, (b) Mo or W, and (c) Co, Ni or mixture thereof, incorporated into a suitable support; (ii) heating the lignocellulosic biomass solids and digestive solvent in the presence of hydrogen, supported hydrogenolysis catalyst and the at least one of ammonia or a source of ammonia thereby forming a product solution containing plurality of oxygenated hydrocarbons and ammonia; and (iii) recycling at least a portion of the ammonia to the hydrothermal digestion unit.
