摘要
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,开发脱砷剂具有重要意义。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取得的最新成果。展望了石油烃脱砷技术的发展方向。
With the complexity of crude oil compositions, the content of arsenic compounds in petroleum hydrocarbons increased gradually. The arsenic compounds poison severely catalysts such as noble metals, which were often used in petroleum chemical industry. It was important that effective arsenic - removing methods and dearsenic agents were developed.In this paper,recent progress of arsenic - removing technologies were reviewed,particularly,recent achievements in removal of arsenic from liquid hydrocarbons were introduced in detail. The research prospect of arsenic - removing technologies was pointed out also.
