Abstract
A delayed coking process in which a flash zone gas oil stream from the bottom of the coker fractionator is upgraded by removing suspended solids and then hydroprocessing the stream to make it more attractive as a feed to a fluidized bed catalytic cracking unit or other processing unit. Removal of the solids allows the stream to be processed in a fixed bed catalytic hydrotreater without plugging of the catalyst bed.
