催化重整高氮原料预加氢技术的开发及工业应用

摘要

中国石化抚顺石油化工研究院成功开发了直馏石脑油掺炼焦化汽油、直馏石脑油掺炼FCC汽油中馏分等高氮含量原料的催化重整预加氢技术及与其配套使用的FH-40C高活1性轻质馏分油加氢精制催化剂.工业应用结果表明:FH-40C催化剂对原料适应性强,加氢脱硫和加氢脱氮活性高,稳定性好；在直馏石脑油中掺炼低于20％(ω)的焦化石脑油或FCC汽油中馏分时,产品质量完全可以满足重整装置进料质量指标要求.除此之外,还开发了配套的FDAS-1脱砷剂和FHRS-1/FHRS-2捕硅剂,应用效果良好.%The technology of catalytic reforming pre-hydrogenation for processing feedstock with high nitrogen content, including straight-run naphtha blending with coker naphtha or FCC naphtha mid fraction, and its tailor made FH-40C hydrorefining catalyst were developed by Fushun Research Institute of Petroleum and Petrochemicals. Commercial running results showed that FH-40C catalyst had good adaptability to various feedstocks, with high HDS and HDN activities and excellent stability;when treating feedstocks of straight-run naphtha blending with less than 20%(w)of coker naphtha or FCC naphtha mid fraction, the qualities of the treated naphtha could well meet the requirements for catalytic reforming feedstock. In addition, FDAS-1 de-arsenic absorbent and FHRS-l/FHRS-2 silicon trap catalysts for compatible use were also developed and they exhibited good combination effect for long-term running of the unit.
