摘要:
PROCESS FOR CARBOHYDRATE TREATMENT STRUCTURAL IN BIOMASS lignocellulosic, PROCESS FOR TREATMENT OF A VEGETABLE BIOMASS WITH CONTENT lignocellulosic UNDERSTANDING carbs STRUCTURAL WITH WATER NATURALLY PRESENT IN BIOMASS FOR PRODUCTION OF CARBS STRUCTURAL more digestible or accessible, PROCESS FOR Amenia RECOVERY AND AN EXPLOSION TREATMENT Ammonia fibers of a lignocellulosic biome, and system. <;UM>; GOVERNMENT RIGHTS STATEMENT <;MV>; - This order received funds from the Department of Energy under contract No. XCO-3-33033-01. The US Government has certain rights with respect to this invention. BACKGROUND OF THE INVENTION (1) Field of the Invention The present invention relates to a process for treating a lignocellulosic biomass with concentrated ammonium hydroxide and preferably with ammonia gas to increase the availability of structural carbohydrates (polysaccharides). pressure steam is preferably used to extract ammonia from biomass for recycling. In particular, the present invention relates to a process which allows efficient conversion of polysaccharides to monosaccharides preferably by enzymatic hydrolysis. (2) Description of the Associated Art A wide variety of methods (eg concentrated or diluted bases or acids, high temperatures, radiation of various types) have been used for biomass pretreatment.PROCESSO PARA TRATAMENTO DE CARBOIDRATOS ESTRUTURAIS EM BIOMASSA LIGNOCELULóSICA, PROCESSO PARA TRATAMENTO DE UMA BIOMASSA VEGETAL COM CONTEúDO LIGNOCELULóSICO COMPREENDENDO CARBOIDRATOS ESTRUTURAIS COM áGUA NATURALMENTE PRESENTE NA BIOMASSA PARA PRODUçãO DE CARBOIDRATOS ESTRUTURAIS MAIS DIGERìVEIS OU ACESSìVEIS, PROCESSO PARA RECUPERAçãO DE AMÈNIA E UM TRATAMENTO DE EXPLOSãO DE FIBRAS DE AMÈNIA DE UMA BIOMASSA LIGNOCELULóSICA, E SISTEMA. <;UM>;DECLARAçãO REFERENTE A DIREITOS GOVERNAMENTAIS<;MV>; - Este pedido recebeu fundos do Departamento de Energia sob o contrato No. XCO- 3-33033-01.
