Sapo-Containing Alumina Comoni-Catalysts for Hydrotreatment of Heavy Oil: Pore Hierarchy as a Key Parameter for Catalyst Stabilization

•The possibility of using SAPO-5 and SAPO-11 in hydrocracking process has been shown.•Lifetime of catalyst depends on support pore hierarchy.•Hierarchical porosity of SAPO makes the catalyst highly active and stable.•The necessity of high-resolved pore hierarchy for such supports has been shown.
