摘要: 以棕榈酸化油和木粉为原料,在超临界甲醇条件下进行共炼反应,考察反应时间、反应温度、搅拌速率对木粉分解率、气化率、轻油产量和重油产量的影响,并对共炼反应条件进行优化。结果表明:在反应温度为300~320 ℃、反应时间为15~30 min的条件下,共炼反应中木粉的最大液化率可达53.0%,油脂转化率达到100%;与在甲醇中直接液化相比,反应体系中加入棕榈酸甲酯共炼,木粉中纤维素、半纤维素和木质素的分解率分别提高18.9%,11.2%,25.0%。

Abstract: The co-refining of acidic palm oil and poplar powder were conducted in supercritical methanol to investigate the effect of reaction temperature and time,stirring speed on the decomposition and gasification rate of wood powder as well as light and heavy oil yields.The optimized reaction conditions are:300—320 ℃ and 15—30 min; the maximum liquefaction ratio is 53.0% under the optimized conditions,and the conversion of the acidic oil is nearly 100%.It was found that the decomposition ratios of cellulose,hemicellulose and lignin are enhanced by 18.9%,11.2% and 25.0%,respectively due to the co-fining with palm acidic oil,compared with the results of direct conversion in supercritical methanol medium.
