摘要
以路易斯酸金属盐为催化剂,对瘦煤进行了热萃取研究。结果表明,催化剂对提高热萃取率起到了促进作用;硫酸锌的催化效果最好,热萃取率为46.1%,最佳用量为5%。
Lean coal solvent hot extraction is studied with Lewis-acid metals as catalyst.The result shows that the catalysts help to improve hot extraction rate,in particular zinc sulfate has the best performance,with hot extraction rate of 46.1% and optimum dosage concentration of 5%.
