中文摘要：
利用高压反应釜,采取程序控制升温的方法,以义马煤为原料,循环油为溶剂,Fe2O3为催化剂和S为助催化剂,在不同反应时间、温度和初始氢压下,测定了义马煤直接液化效果的影响因素.结果表明,随着温度升高,转化率呈减小趋势,而油产率随着反应温度的增加呈现出先增加后减小的趋势,在380℃时油产率达到最大值;随着初始压力的增加,转化率和油产率都有所增加,但增加幅度很小,在9 MPa时油产率达到最大值;随着反应时间的增加,转化率和油产率都有所增加,在120 min时油产率和转化率均达到最大值.
英文摘要：
Study of Yima coal direct liquefaction under different reaction time,temperature,and initial hydrogen pressure was probed into.The experiment was investigated by reaction kettle with circulation oil and Fe2O3 and S catalyst.The results indicated that the best reaction conditions were at 380 ℃,9 MPa,120 min according to the oil yield,and the conversion of liquefaction decreased with the temperature,but the oil yield of liquefaction increased firstly and then decreased with the temperature,and the conversion and oil yield of liquefaction increased with the initial cool hydrogen pressure and the reaction time.
