Heavy oil hydrocracking process

摘要

A process for the production of high yields of high quality products from heavy hydrocarbonaceous feedstock comprising a two-stage, close-coupled process. The first stage comprises a thermo-catalytic zone into which is introduced a mixture comprising the feedstock, coal, a liquid catalyst precursor, and hydrogen. The second, close-coupled stage comprises a catalytic-hydrotreating zone into which substantially all the effluent from the first stage is directly passed and processed under hydrotreating conditions.

1. A process for conversion of heavy oils to produce lower boiling hydrocarbon products comprising;
dispersing finely divided coal and a liquid catalyst precursor in a heavy oil feedstock, heating and passing the dispersed mixture together with hydrogen to a first reaction zone in which the liquid catalyst precursor is converted into fine solid catalyst particles, reducing the product of the first reaction zone in temperature and passing the product to a second reaction zone having a supported hydrotreating catalyst, with the first and second reaction zone close-coupled, the first reaction zone a thermo-catalytic reactor(s) and the second reaction zone a catalytic-hydrotreating reactor(s); and recovering the product of the second reaction zone.
