【摘要】 以木粉和甲醇为原料,在高压反应釜中进行木粉在超临界甲醇中的液化分解反应,研究甲醇与木粉的配比、反应时间、反应压力、催化剂种类及用量对木粉分解率、气化率和液化率的影响。结果表明,以NaOH为催化剂,在甲醇与木粉质量比为4.5、反应温度为320℃、反应时间为1h的条件下,木粉液化率达到43.3%。更多还原

【Abstract】 The liquefaction of wood powder in supercritical methanol was investigated under different reaction conditions.The results indicate that the liquefaction,decomposition and gasification rate of wood powder were affected by the ratio of methanol to wood powder,reaction temperature and time,as well as type and amount of catalyst.At the best conditions:methanol to wood powder ratio of 4.5,temperature of 320 ℃,reaction time of 1h,and NaOH as catalyst,the liquefaction rate achieves 43.3%.更多还原
