Abstract: Based on a novel catalyst preparation technology platform defined as "Reactant-active phase Optimization & Cost-effective Key Technology，ROCKET+", a new generation of high-performance hydrotreating catalyst RN-510 for vacuum gas oilhas been successfully developed. Compared with RN-32V, the relative desulfurization activity of the RN-510 catalyst is increased by 36%—54%, and the industrial loading density is reduced by about 39%. At the same time, the catalyst has higher activity stability and extremely high cost-effectiveness. The RN-510 catalyst is suitable for processing straight run gas oil and partially blended with coker gas oil under medium and high pressure conditions, providing high-quality raw materials for fluidized catalytic cracking units.
