Abstract
This invention comprises a process for hydroprocessing a petroleum oil containing soluble metals compounds while suppressing the accumulation of coke within the hydroprocessing zone, comprising the steps of (a) forming a mixture comprising particulate coal and a petroleum oil containing soluble metal compounds to form a feed slurry; and (b) contacting said feed slurry with added hydrogen in said hydroprocessing zone under hydroprocessing conditions to produce an effluent comprising a normally liquid portion having a reduced soluble metals concentration and undissolved solids containing metal from said soluble metals compounds in said petroleum oil.
