Red mud as a first-stage catalyst in a two-stage, close-coupled thermal catalytic hydroconversion process

摘要

A process for the production of transportation fuels from heavy hydrocarbonaceous feedstock is provided comprising a two-stage, close- coupled process, wherein the first stage comprises a hydrothermal zone into which is introduced a mixture comprising a feedstock and red mud having coke-suppressing and demetalizing activity, and hydrogen; and the second, close-coupled stage comprises a hydrocatalytic zone into which substantially all the effluent from the first stage is directly passed and processed under hydrocracking conditions.
