Alumina with tuned textural properties were prepared by addition of a porogen during peptisation of boehmite. The obtained alumina present improved textural properties that allowed to prepare highly loaded CoMo catalysts while maintaining a satisfying molybdenum dispersion. Performance in thiophene HDS could be increased by a factor 1.5. The most efficient solid in thiophene HDS was evaluated in the HDS of a SRGO under industrial conditions. It was found significantly more active than a CoMo catalyst prepared on a commercial alumina.
