RED MUD AS A FIRST-STAGE ADDITIVE IN A TWO-STAGE, CLOSE-COUPLED THERMAL CATALYTIC HYDROCONVERSION PROCESS

摘要

ABSTRACT OF THE DISCLOSUREA process for the production of transportationfuels from heavy hydrocarbonaceous feedstock is providedcomprising a two-stage, close-coupled process, wherein thefirst stage comprises a hydrothermal zone into which isintroduced a mixture comprising a feedstock and red mudhaving coke-suppressing and demetalizing activity, andhydrogen; and the second, close-coupled stage comprises ahydrocatalytic zone into which substantially all theeffluent from the first stage is directly passed andprocessed under hydrocracking conditions. In alternativeembodiments, the red mud may be presulfided ormetals-impregnated.
