20140295509 | Pre-Treatment of Cellulosic Material - A method of pre-treating a cellulosic material before hydrolysis is provided. The method comprises the steps of: impregnating the cellulosic material with a reactive water-soluble gas, such as sulphur dioxide (SO | 10-02-2014 |
20140154746 | Methods for Improvement of Enzymatic Hydrolysis of Lignocellullosic Material - The present invention relates to a method of enzymatic hydrolysis of a lignocellulosic material, comprising the steps of: a) pretreating the lignocellulosic material to obtain a slurry having a pH of less than 6; b) adding NaOH, Ca(OH) | 06-05-2014 |
20110269223 | CORROSION INHIBITION - The present invention relates to a methods, products and uses for inhibiting corrosion. A provided method comprises the steps of: a) subjecting cellulosic biomass to hydrolysis to obtain a hydrolysate liquid; b) optionally, subjecting the hydrolysate liquid from step a) to one or more of the steps of further hydrolysis, fermentation and/or distillation; and c) using the hydrolysate liquid from step a) or b) to inhibit corrosion. | 11-03-2011 |
20110217746 | FERMENTATION PROCESS STARTING FROM CELLULOSIC BIOMASS AND INVOLVING THE RECIRCULATION OF DETOXIFIED STILLAGE INTO THE PROCESS - A method for preparing a target chemical derivable from cellulosic biomass, involving detoxification of spent hydrolysate is provided. The method comprises the steps of providing cellulosic biomass, subjecting the cellulosic biomass to aqueous pretreatment, aqueous hydrolysis, and fermentation under conditions in which at least a part of the fermentable sugars are fermented into a primary target chemical, separating the primary target chemical from the fermented hydrolysate to provide a spent hydrolysate comprising inhibitory substances and detoxifying the spent hydrolysate by decreasing the concentration of at least one of the inhibitory substances using a detoxification biocatalyst selected from the group consisting of wild type, mutant and recombinant filamentous fungi and recirculating at least a part of the detoxified spent hydrolysate, optionally after further purification. | 09-08-2011 |
