20120009632 | PROCESS FOR PRODUCING ALCOHOL AND OTHER BIOPRODUCTS FROM BIOMASS USED IN THERMAL CONVERSION TO ENERGY AND STEPWISE ENZYMATIC HYDROLYSIS PROCESS FOR CELLULOSIC FIBER - A method for the production of alcohol and other bioproducts hemicelluloses extracted from biomass prior to thermal conversion of the biomass to energy. The process can be integrated with the host plant process to minimize the energy loss from extracting hemicelluloses. Also disclosed is a Stepwise enzymatic break down of cellulose fibers from a pulping operation which is performed with the redeployment of equipment and vessels contained within typical existing pulp and paper manufacturing mills. The preferred feedstock is highly delignified pulp from acid or alkaline pulping process or from bleaching stage. | 01-12-2012 |
20110195468 | SYSTEM AND PROCESS FOR SEPARATING PURE CHEMICALS FROM BIOMASS EXTRACT - A system or plant and method for the production of pure alcohol, acetic acid or its derivatives from the extract containing hemicelluloses filtered after extraction of woody biomass or directly extracted from woody biomass. The process can be integrated with the host plant process to minimize the effect of loss of heat value from the extracted hemicelluloses and reduce the loading to the effluent plant. | 08-11-2011 |
20110003352 | PROCESS FOR THE STEPWISE TREATMENT OF LIGNOCELLULOSIC MATERIAL TO PRODUCE REACTIVE CHEMICAL FEEDSTOCKS - A method for the fractionation of lignocellulosic materials into reactive chemical feedstock in a batch or semi continuous process by the stepwise treatment with aqueous aliphatic alcohols in the presence of sulfur dioxide or acid. Lignocellulosic material is fractionated in a fashion that cellulose is removed as pulp, or converted to esterified cellulose, cooking chemicals are reused, lignin is separated in the forms of reactive native lignin and reactive lignosulfonates and hemicelluloses are converted into fermentable sugars, while fermentation inhibitors are removed. In an integrated vapor compression stripper and evaporator system, aliphatic alcohol is removed from a liquid stream and the resulting stream is concentrated for further processing. | 01-06-2011 |
