【摘要】 研究了苯胺溶剂在不同时间、不同煤/溶比和不同温度等实验条件下对神府煤的溶胀,并用扩散理论对煤的溶胀过程进行了描述.结果表明,在溶胀时间为2h,煤/溶比为0.05,温度为80℃的溶胀条件下,神府煤在苯胺中的平衡溶胀度达到最大.溶胀动力学表明,煤的溶胀是受Case扩散控制为主的过程.更多还原

【Abstract】 The effects of swelling time, temperature, types of solvent, and the ratio of coal vs solvent on the swelling properties of Shenfu coal (SFC) were studied.The results show that the maximum degree of equilibrium swelling of SFC is obtained under the conditions of 80 ℃, 2 h and 0.05 g/mL of coal vs solvent. The study of swelling dynamics indicates that the swelling process of SFC in aniline can be illustrated by CaseⅡdiffusion.更多还原
