Combination process for producing high quality metallurgical coke

摘要

A process for producing high quality metallurgical coke from hydrocarbonaceous charge stock containing coke precursors which comprises: (a) admixing said hydrocarbonaceous charge with a hereinafter described hydrocarbonaceous recycle stream; (b) introducing the resulting admixture into a coking zone maintained at coking conditions to produce coke and a hydrocarbonaceous effluent having a reduced level of coke precursors; (c) introducing at least a portion of said hydrocarbonaceous effluent into a hydrodesulfurization zone maintained at hydrodesulfurization conditions; (d) recycling at least a portion of the resultant desulfurized hydrocarbon of step (c) to step (a) as said hydrocarbonaceous recycle stream.
