| Abstract | 本发明涉及固体酸催化剂以及废弃生物质资源化利用技术领域，特别涉及杂多酸催化剂及其制备方法、以及利用杂多酸催化剂催化水解生物质的方法。该杂多酸催化剂的结构通式为[(CH3)3N(CH2)2OH]nH5‑nCeW12O40，0 |
| Other Abstract | The invention relates to the technical field of solid acid catalysts and waste biomass resource utilization, in particular to a heteropolyacid catalyst, a preparation method of the heteropolyacid catalyst and a method for catalytically hydrolyzing biomass by using the heteropolyacid catalyst. The structural general formula of the heteropolyacid catalyst is [(CH3)3N(CH2)2OH]nH5-nCeW12O40, wherein n is greater than 0 and less than or equal to 5, the preparation method comprises the following steps: adding an acidified sodium tungstate aqueous solution into a cerium chloride aqueous solution, performing heating reflux, and then obtaining a filtrate which at least contains cerium-tungsten compounds; adding a first acid agent into the filtrate, and heating and refluxing to acidify the cerium-tungsten compound; adding a second acid agent into the acidified cerium-tungsten compound, extracting with diethyl ether, and drying the extract by distillation to obtain cerium-tungsten acid; dissolving cerium tungstic acid in water, and adding a choline chloride aqueous solution for reaction to obtain the heteropolyacid catalyst. The catalyst has the advantages of both a homogeneous catalyst and a heterogeneous catalyst. |
