【摘要】 采用超深度加氢脱硫催化剂RS-1000,分别以高硫直馏柴油和催化裂化柴油为原料,在中试装置上进行满足欧Ⅴ排放要求的清洁柴油生产的试验,并考察RS-1000催化剂在工业装置上长期生产硫含量小于10μg/g清洁柴油的性能。结果表明,以直馏柴油或直馏柴油掺炼10%的催化裂化柴油为原料,在较高空速(1.7～2.0h-1)和常规反应温度、压力下,或以催化裂化柴油为原料,在较低空速(1.00～1.25h-1)和常规反应温度、压力下,采用RS-1000催化剂,均可生产出硫含量小于10μg/g的清洁柴油,且在运转过程中催化剂具有良好的选择性和稳定性。更多还原

【Abstract】 Tests of adopting ultra deep hydrodesulphurization catalyst RS-1000 to produce clean diesel fuel for meeting the requirements of EN590:2009 were conducted on the pilot plant using high sulfur straight run gas oil(SRGO)and FCC LCO as feedstock respectively.Furthermore,the catalytic performance of RS-1000 catalyst during long term producing clean diesel fuel(sulfur content less than 10μg/g)in a commercial unit was reviewed.Test results showed that clean diesel fuel with sulfur content less than 10μg/g could be produced by using RS-1000 catalyst under conventional reaction temperature and pressure,yet for SRGO and SRGO plus 10% LCO the LHSV should be higher(1.7—2.0h-1),and for LCO the LHSV could be lower(1.0—1.25h-1).The commercial application results showed that RS-1000 catalyst exhibited excellent selectivity and stability.更多还原
