摘　　要：CH－20催化剂以Mo－Ni为加氢活性组分，采用Al2。（SO4）3和NaAlO2为原料路线制备Al2O3。载体，具有适宜的孔结构，加氢活性高，稳定性好，适用于CGO加氢处理制备催化裂化原料。试验结果表明。在中压（氢压6．4MPa）下，加氢处理氛含量0．49％（碱氮0．19％）、硫含量0.92％的管输CGO，其脱氮率为76％～78％，脱碱氛单～85％，脱硫率在95％以上。该催化剂于1997年2月在长岭炼油化工总厂300kt／a加红装置上工业应用，在反应器入口压力6．3MPa（氢分压5．SMPa）、人口温度340C的条件下加工氮含量0．45％（碱氛0．165％）的CGO，加氢焦化蜡油（HT－CGO）的碱氮＜500μg／g，工业应用效果良好。CH-20 hydrotreating catalyst, using Mo-Ni as hydrogenating component and Al203 Prepared fromAlz(SO4)3 and NaAlO2 as support,has a suitable pore structure,high hydrogenating activity and good stabili-ty. It can be used in coker gas oil (CGO) hydrotreating process to prepare FCC ftedstocks. The test resultsshow that using CH-20 catalyst under moderate pressure (H, partial pressure 6. 4MPa) and hydrotreatingpipeline CGO with N content of O. 49% (basic-nitrogen O. l9% ) and S content of 0. 92%, hydrodenitro-genation (HDN) efficiency of 76. 0% ～78. O%,de-basic-nitrogen effieiency of about 85% and desulfurizationefficiency of up to 95% or even higher can be attained. CH-20 was first commercially used on a 300kt/d hy-drotreating unit at Changling Refinery in February, 1997 with good hydrotreating results. Under inlet pres-sure of 6. 3MPa (H2 partial pressure 5. 8MPa) and in1et temperature of 340 C and with CGO of O. 45% N con-tent (basic-nitrogen O. l65% ) as feedstock, tbe basic-nitrogen content in hydrotreated coker gas oil (HT-CG0) is less than 5O0μg/g
