2-甲基呋喃,在国內是从糠醛以铜铝合金为催化剂催化加氢制得的。去年初,生产不很正常,收率低,催化剂寿命短,故铜铝消耗量很大。本工作目的在于寻找更好的新催化剂。通过催化剂的筛选的研究,找到一个Cu-Cr/AI_2O_3,新催化剂,其Cu:C:Al_2O_3为15:2.5:82.5.小实验2-甲基呋喃收率为了70％,1克催化剂可得30克左右2-甲基呋喃。在此基础上,进一步研究改进制备载体及催化剂的方法,找到了以偏铝酸钠溶液通CO_2沉淀
2-methyl furan, in the country from the furfural to copper-aluminum alloy catalyst for catalytic hydrogenation. Early last year, the production is not very normal, low yield, catalyst life is short, so a lot of copper and aluminum consumption. The purpose of this work is to find a better new catalyst. Through the study of catalyst screening, a Cu-Cr / AI_2O_3 new catalyst with a Cu: C: Al_2O_3 of 15: 2.5: 82.5 was found. The experimental yield of 2-methylfuran was 70% About 2-methyl furan. On this basis, further study to improve the preparation of the carrier and the catalyst method, found to sodium aluminate solution through CO2 precipitation
