硫磺回收催化剂及工艺技术

综述了20世纪70年代以来中国石化硫磺回收催化剂及工艺技术方面的进步。回顾了LS系列硫磺回收及尾气加氢催化剂的发展历程,介绍了催化剂主要性能及工业应用情况,同时对大型引进硫回收装置催化剂国产化进行了详述。总结了通过对已引进的硫磺回收装置消化吸收,借鉴国外先进技术和有益经验,中国石化开发的具有自主知识产权的成套工艺技术,提出了对新建大型硫磺回收装置的设计原则及建议。

CATALYST AND PROCESS TECHNOLOGY FOR SULFUR RECOVERY

Progresses in catalyst and process technology for sulfur recovery since the 1970s are reviewed. The development of the LS series catalysts for sulfur recovery and off-gas hydrogenation, and the performance and industrial applications are summarized, and the localization of the imported catalyst of sulfur recovery for large scale plant is described in detail. The process technologies developed by SINOPEC with complete self-owned intellectual property is summarized based on digestion and absorption of the imported plant and relevant advanced technologies and experiences. The design principles and advices for newly built large scale sulfur recovery plant are proposed.
