摘要
为了研究油脂及其甲酯对杨木粉液化的促进作用,采用大豆油(或甲酯)、杨木粉和甲醇为原料,在高压釜中研究了它们的共炼行为。实验结果表明,甲酯能够显著提高杨木粉在甲醇中的分解率;大豆油与杨木粉在甲醇中共炼,大豆油也能显著提高杨木粉的分解率。大豆油与杨木粉在甲醇中共炼的反应时间以60 min为宜,温度以320℃为宜。共炼能够同时提高杨木粉中纤维素、半纤维素和木质素的分解率,其中,木质素分解率的提高幅度最大。
To study the promotion effect on wood powder liquefaction in super critical methanol, soybean oil and/or fatty acid methyl esters were used, and co-refining reaction in high pressure autoclave was also studied. It was showed that the decomposition ratio of wood powder was promoted by fatty esters and soybean oil. The optimized co-refining reaction condition is 60 min and 320 ℃ . The decomposition rate of cellulose, hemicellulose and lignin was all enhanced by co-refining, and the relative decomposition rate of lignin increased most.
