高稳定性超深度脱硫和多环芳烃深度饱和柴油加氢催化剂RS-3100的开发

基于对加氢催化剂失活因素如（积炭形成、活性相长大）的有效控制,相继开发了构建通畅扩散孔道的载体制备技术、稳定活性相的金属负载技术以及削减活性位积炭的催化剂制备技术,由此创建了“反应物分子与活性相最优匹配”的新型催化剂制备技术（ROCKET+技术）平台。基于该平台成功开发了高稳定性超深度脱硫和多环芳烃深度饱和柴油加氢催化剂RS-3100。与参比剂相比,RS-3100催化剂的稳定性提高30%以上,工业装填堆密度降低20.5%,具有高性价比。RS-3100催化剂适合于中高压、原料中含有二次加工柴油的加氢装置,可以在较缓和条件下生产硫质量分数低于10 μg/g、多环芳烃质量分数小于7%的国Ⅵ标准柴油调合组分。

DEVELOPMENT OF DIESEL HYDROGENATION CATALYST RS-3100 WITH HIGHLY STABLE ULTRA-DEEP DESULFURIZATION AND DEEP AROMATIC SATURATION PERFORMANCE

Based on the effective control of the deactivation factors of hydrogenation catalysts such as the formation of coke deposits and the growth of the active phase,the support preparation technology to build a smooth diffusion channel,the metal loading technology to stabilize the active phase,and the catalyst preparation technology to reduce the carbon deposition on active phase have been successively developed. Therefore,a novel catalyst preparation technology platform defined as "Reactant-active Phase Optimization & Cost-effective Key Technology(ROCKET+) was established. Based on this platform,RS-3100,a diesel hydrogenation catalyst with highly stable ultra-deep desulfurization and deep aromatic saturation performance,was successfully developed. Compared with previous generation catalyst,the stability of RS-3100 is improved by more than 30%,and the industrial packing density is reduced by more than 20%,which has a very high performance-price ratio. RS-3100 is suitable for medium and high pressure hydrogenation units fed by the secondary processed diesel fraction,and it can realize the production of the national Ⅵ standard diesel products with the mass fraction of the sulfur content less than 10 μg/g and the mass fraction of the polycyclic aromatic hydrocarbon less than 7% under mild operation conditions.
