Ru/MCM-41催化葡萄糖加氢制备山梨醇的研究
Study on hydrogenation of glucose into sorbitol by Ru/MCM-41 catalyst
摘要
Abstract
Sorbitol was produced from glucose by hydrogenation reaction with MCM-41 molecular sieve supported Ru catalysts prepared by formaldehyde reduction process. Effects of various factors reaction temperature,reaction time,and recycling index of Ru/MCM-41 on glucose conversion and sorbitol yield were discussed. Experimental results had shown that the highest sorbitol yield of 94. 43% could be got at the temperature of 120℃ and reacted for 1. 5h when the glucose concentration was 10%,the amount of catalyst was 20%(calculating by the dosage of glucose),and the glucose conversion was as high as 100%. At the mean time,research on catalyst recyling had shown that Ru/MCM-41 was an ideal catalyst for hydrogenation of glucose,which could be recycled three or four times.关键词
