保护甲醇催化剂与醇烃化催化剂的常温精脱硫工艺

Fine Desulphurization of Atmospheric Temperature in Protecting of Methanol Catalyst and Methanol Olefination Catalyst

介绍了具有保护甲醇催化剂和醇烃化催化剂作用的JTL-1、JTL-4、JTL-5等3种常温精脱硫工艺及其特点,总结了其应用效果。结果表明,上述3种工艺均可将原料气中的总硫脱除至〈0.1×10-6,催化剂使用寿命分别已超过3~5年。

Author has introduced the three kinds of fine de-sulfur processes at atmospheric temperature and their characteristics for protecting methanol catalysts of JTL-1,JTL-4 and JTL-5 etc.,has summarized their application effect.The result indicates that the abovementioned three kinds of processes can make the total sulfur in the raw gas to be removed to less than 0.1×10-6,the service life of catalysts exceeds separately 35 years.
