Methods and systems for hydroprocessing heavy oil feedstocks to form an upgraded material involve the use of a colloidal or molecular catalyst dispersed within a heavy oil feedstock, a pre-coking hydrocracking reactor, a separator, and a coking reactor. The colloidal or molecular catalyst promotes upgrading reactions that reduce the quantity of asphaltenes or other coke forming precursors in the feedstock, increase hydrogen to carbon ratio in the upgraded material, and decrease boiling points of hydrocarbons in the upgraded material. The methods and syst...
1. A hydroprocessing system for hydroprocessing a heavy oil feedstock to form coke and upgraded hydrocarbon products, comprising: a heavy oil feedstock comprised of a substantial quantity of hydrocarbons having a boiling point greater than about 343° C., asphaltenes or other coke forming precursors, and a colloidal or molecular catalyst dispersed throughout the feedstock;a pre-coking hydrocracking reactor configured to heat or maintain the heavy oil feedstock at a hydrocracking temperature together with hydrogen and convert at least a portion of higher b...
