以微晶纤维素为研究对象,HZSM-5为催化剂,系统考察了原料/溶剂水质量比、反应温度、反应时间、催化剂用量、催化剂硅铝比等对催化液化效果的影响。结果表明:在纤维素/溶剂水的质量比为1/20、反应温度280℃、反应时间40min、HZSM-5催化剂(硅铝比为28)用量为原料质量分数的5%时,可以得到较好的催化液化效果,且HZSM-5催化剂可以多次重复使用。 Taking microcrystalline cellulose as the research object, HZSM-5 was used as a catalyst to systematically investigate the effect of the raw material / solvent water mass ratio, the reaction temperature, the reaction time, the amount of the catalyst and the silica to alumina ratio on the catalytic liquefaction effect. The results showed that when the mass ratio of cellulose / solvent water was 1/20, the reaction temperature was 280 ℃, the reaction time was 40 min, the amount of HZSM-5 catalyst (Si / Al ratio 28) was 5% of the mass fraction of raw materials, Good catalytic liquefaction effect, and HZSM-5 catalyst can be repeatedly used.
