This work brie?y introduces pompous biomass pretreatment and hydrolysis techniques, and reviews in detail the characteristics of biomass hydrolysis for ?ve types of whole acid catalysts grouped as H-form zeolites, transition-metal oxides, cation-exchange resins, supported solid acids and heteropoly compounds. carboniferous solid acid (CSA) catalysts ar considered as the most shiny catalyst for cellulose hydrolysis, since they provide welcome access of reactants to the acidic sites of SO3H groups. full(prenominal) glucose yields of up to 75% with 80% selectivity have been achieved at cl  C for 24 h with...If you want to get a full essay, order it on our website: Orderessay
