RS-1加氢精制催化剂的工业应用

COMMERCIAL APPLICATION OF RS 1 HYDROTREATING CATALYST

为适应加工高硫高氮催化重整原料和加大装置处理量的需要，石油化工科学研究院开发成功了高空速石脑油加氢精制催化剂ＲＳ－１。经长岭炼油化工总厂等催化重整预加氢装置的长期工业应用表明，在压力１．６～２．０ＭＰａ、温度２６０～２８０℃、氢油体积比６０～９０、体积空速８～１０ｈ－１的条件下，可用硫、氮含量分别为≤８００μｇ／ｇ、≤３．０μｇ／ｇ的直馏汽油生产出硫、氮含量都＜０．５μｇ／ｇ、其它杂质含量合格的重整进料；当用硫、氮含量分别≤３５０μｇ／ｇ、≤１０μｇ／ｇ的掺焦化汽油的混合汽油为原料时，在压力２．０～３．０ＭＰａ、温度２８０～３００℃、氢油体积比１００～２００、体积空速６．０～８．０ｈ－１的条件下精制，产物符合重整进料要求。因此，ＲＳ－１催化剂具有加氢脱硫脱氮活性高、烯烃饱和能力强、机械强度好、稳定性好的优点，可广泛用于上述原料的加氢精制。

A naphtha hydrotreating catalyst RS 1 was developed for processing high sulfur and nitrogen content reforming feedstock at high space velocity. The commercial applications in the Refinery of Baling Petrochemical Company, etc. indicated that a reforming feedstock with less than 0.5 μg/g sulfur and nitrogen and minor impurities could be produced from a straight run gasoline with a sulfur and nitrogen content of less than 800 μg/g and 3.0 μg/g respectively at the operating conditions of a pressure of 1.6～2.0 MPa, a temperature of 260～280 ℃, a H 2/oil volume ratio of 60～90 and a LHSV of 8～10; a qualified reforming feedstock could also be obtained from a straight run gasoline blended with coker gasoline having a sulfur and nitrogen content less than 350 μg/g and 10 μg/g respectively at the operating conditions of a pressure of 2.0～3.0 MPa, a temperature of 280～300 ℃, a H 2/oil volume ratio of 100～200 and a LHSV of 6～8. RS 1 catalyst has the advantages of high activity for sulfur and nitrogen removal, good mechnical strength and stability, which can be widely used in hydrotreating.
