脱砷剂研究进展

The Research and Development of Dearsenical Agent

随着世界石油资源不断贫化,石油烃中的砷化物含量越来越高。由于砷化物对炼油及石油化工过程中的催化剂具有严重的毒害作用,探索有效的脱砷方法和脱砷剂成为了学术界和工业界普遍关心的课题。本文就石油烃脱砷及脱砷剂的最新发展进行了较为全面的评述,总结了近年来脱砷技术领域,特别是液态石油烃脱砷所取得的最新成果。进一步展望了石油烃脱砷技术发展的新动向。

With the complexity of crude oil, the content of arsenic compounds in oil products increased gradually. The arsenic compounds severely poison the catalysts such as the noble metals, which were often used in petroleum chemical industry. Hence, the development of effective arsenic-removing methods and/or catalysts becomes a commonly concerned topic. In this paper, the recent progress of arsenic-removing technologies were reviewed, particularly, the recent achievements of new material and progress for removal of arsenic from liquid hydrocarbons were introduced in detail. The research prospect of arsenic-removing technologies was pointed out also.
