    摘要: Biomass is contacted with an aqueous media to form an extracted biomass. An aqueous liquor separated from the extracted biomass is treated with a purification substrate to form a treated carbohydrate stream having less than 35% of the sulfur content and less than 35% of the nitrogen content, based on the untreated aqueous liquor stream, prior to contact with an aqueous phase reforming catalyst to form oxygenated intermediates that can be further processed to form a liquid fuel. An extracted biomass solids stream is also separated from the extracted biomass which is contacted with a first digestive solvent and then a second digestive solvent to form a solubilized pulp. This solublilized pulp may be combined with the aqueous liquor stream or combined to an aqueous reforming reaction system or recycled to the aqueous media to be processed further for an effective process to produce the liquid fuel.

    摘要: The present invention is an improvement upon the process for the production of 1,3-propanediol wherein an aqueous solution of 3-hydroxy propanal is formed, catalyst, if any, used in said formation is removed from the solution, sodium hydroxide is added to the solution to neutralize any acid therein such that the pH is at least about 5, the neutralized aqueous solution is subjected to hydrogenation to produce a crude 1,3-propanediol mixture which is distilled to produce 1,3-propanediol, water, and reactive heavy components. The improvement on this process comprises replacing the sodium hydroxide with a hydroxide selected from the group consisting of ammonium hydroxide, alkali metal hydroxides other than sodium hydroxide, and alkaline earth metal hydroxides to reduce the viscosity of the reactive heavy components.
