摘要
比较claus法硫磺回收装置的尾气处理方法,认为Sulfreen法工艺适合我国国情.在我国适用于Sulfreen法的CT6-4催化剂,是四川石油管理局天然气研究所研制成功的,是浸渍活性金属化合物的氧亿铝催化剂,它不仅有好的低温Claus反应活性,而且有良好的抗硫酸盐化性能.文中用试验数据与同类的西德鲁奇公司的RP-AM2-5催化剂进行比较,50循环后,其活性下降速度、催化剂中硫酸根含量增长速度、比表面积下降速度、孔半径增长速度都比较优越,是我国发展低温Claus工艺技术的良好的配套催化剂.
A comparion of tail gas treating processes for Claus sulfur recovery units indicated that the Sulfreen process is more appropriate for China.A new catalyst,type CT6-4,prepared by impregnating certain active metal compound on alumina was developed for this process.It has not only superior low-temperature Claus activity but also good anti-sulfation property.Comparison tests conducted with CT6-4 catalyst and RP-AM2-5 catalyst of Lurgi Company showed that,after 50 cycles,the deactivation rate,the increase of sulfate content,the reduction of specific surface area and the increasing of pole radius of the former are all better than those of the later.
