To improve the catalytic performance of red mud (RM) for slurry-phase hydrocracking of vacuum residue, macro-mesoporosity was introduced into RM using polystyrene and Pluronic F-127 as co-templates in this study. The obtained macro-mesoporous red mud

In this study, red mud (RM) was used as a catalyst in slurry-phase hydrocracking of vacuum residue (VR) in batch system. Without RM, thermal cracking occurred and a lighter fraction and higher conversion was achieved than in the presence of catalyst.

Molybdenum nitrides were prepared by temperature-programmed reduction of MoO3 with flowing NH3. They were tested for indole HDN and benzothiophene HDS. Too low or high NH3 space velocity was inadequate to produce high surface area Mo nitride. The tem
