The problems existed in the old process of crude benzene hydrogenation and equipment were analyzed. The process was improved and the capacity was enhanced through adding a pretreatment apparatus before the hydrogenation unit. 分析了原粗苯加氢工艺与装置存在的问题,通过在加氢单元前增加预处理装置,完善了粗苯加氢工艺,提高了装置的产能,生产的轻苯、重苯都达到了设计要求;
In this paper, reviews on progress in the catalytically hydrogenation of carbon tetrachloride to chloroform in liquid phase are introduced, including reaction mechanism assumption, catalyst design, catalyst preparation, catalyst characterization, catalytic performance test apparatus, reaction kinetics and analysis of industrial catalyst. 综述了四氯化碳催化氢化生成氯仿的研究进展,包括反应机理的假设、催化剂设计、催化剂制备、催化性能评价设备、反应动力学、催化剂工业化分析等。
