高选择性加氢改质系列技术及应用

摘要

The high selectivity hydro - upgrading series technologies and their commercial applications were introduced. The medium pressure hydro - up-gradingf MHUG) technology had good stock adaptability and high operating flexibility, which could increase cetane number of diesel by 15 -20 units and produce clean diesel from inferior stocks. The zoning feeding hydro - upgrading ( MHUG - II ) technologycould improve the selectivity of diesel, decrease hydrogen consumption and increase diesel yield. And the reforming stock yield maximized hydro - upgrading ( MHUG - N) technology could produce high quality reforming stock and significantly increase cetane number.%介绍了高选择性加氢改质系列技术及其工业应用情况.中压加氢改质(MHUG)技术具有原料适应性好,产品方案灵活,柴油十六烷值可提高15～ 20个单位,可由劣质原料生产清洁柴油.分区进料灵活加氢改质(MHUG -Ⅱ)技术提高了加氢改质选择性,降低了氢耗,增加了柴油收率.采用多产重整料加氢改质( MHUG -N)技术可以生产优质重整原料,同时进一步提高柴油质量.
