Zn-Ca-Fe氧化物催化水解微晶纤维素
Hydrolysis of Microcrystalline Cellulose over Zn-Ca-Fe Oxide Catalyst
摘要
Abstract
A series of composite metal oxides were prepared through coprecipitation with urea as a precipitator and calcination at high temperature, and were used as catalysts in hydrolysis of microcrystalline cellulose to glucose. Performances of the catalysts in the hydrolysis were tested. Results showed that Zn-Ca-Fe oxide was an excellent catalyst. Under the reaction condition of temperature 160 ℃, reaction time 20 h, stirring speed 400 r/min, microcrystalline cellulose dosage 2.0 g, Zn-Ca-Fe oxide catalyst dosage 0. 9 g and H2O 200 mL, conversion of microcrystalline cellulose and yield of glucose in the hydrolysis were 42.56 ％ and 69.20 ％, respectively. The hydrolysate solution was still neutral after the reaction. The Zn-Ca-Fe oxide could be reused for 5 times under the above conditions without obvious catalyst deactivation.关键词
