ABSTRACT:
A two-stage catalytic hydroconversion process using a large-pore catalyst in the first stage reactor and a small-pore catalyst in the second stage reactor in the two-stage process for hydroconversion of coal or petroleum asphaltene feed materials to produce distillate liquid fuels. The large-pore catalyst is characterized by having pore diameters larger than 1000.ANG. occupying a major portion of the catalyst total pore volume of 0.2 to 1.0 cc/gm, and the small-pore catalyst is characterized by having pore diameters smaller than 1000.ANG. occupying a major portion of the catalyst total pore volume.
