The aim of this study was to understand the impact vacuum gas oil (VGO) properties on deactivation rate a hydrocracking catalyst (nickel–molybdenum sulfide dispersed carrier containing USY zeolite). For purpose, two hydrotreated feeds different densities, organic nitrogen (∼120–150 ppmw) and aromatic content, were hydrocracked under operating conditions that favor deactivation, is, high tempera...

The catalytic performance of a hydrocracking bifunctional catalyst and consequently its activity loss depend on the balance between metal (M) acid (A) functions. Commonly, function is reputed to stabilize should therefore alleviate deactivation. In order test this hypothesis, study aimed assess impact oxide (MoO3) content deactivation vacuum gasoil (nickel-molybdenum sulfide dispersed carrier c...

Designing the catalyst that can favor both N2 activation and N species hydrogenation is essential for ammonia production. In October issue of Chem Catalysis, Guo et al. report a new strategy through “activation” inactive Cr-based synthesis by creating [BaCrHN] structure.
