A method is described for treating a hydrocarbon oil feedstream to a delayed coking unit to maximize the ratio of the yield of liquids-to-gases, and to minimize the formation of coke which includes: a. mixing an oil-soluble catalyst with the hydrocarbon oil feedstream to produce a uniform mixture; b. contacting the catalyst-containing hydrocarbon oil feedstream with an excess of hydrogen under predetermined conditions that are favorable to maximizing the solubility of the hydrogen in the feedstream in a hydrogen distribution zone that is upstream of the coking unit; c. introducing the feedstream containing the solubilized catalyst and dissolved hydrogen, and the excess hydrogen gas into a flashing zone; d. recovering from the flashing zone a hydrogen gas stream and a single-phase hydrocarbon oil feedstream containing dissolved hydrogen and catalyst; e. maintaining the hydrocarbon oil feedstream containing dissolved hydrogen and catalyst under single-phase conditions to promote the reaction of the dissolved hydrogen with free radicals formed in the feedstream and to promote the catalyzed hydrodesulfurization of any sulfur-containing compounds present in the feedstream; f. introducing the catalyst-containing feedstream into a coking furnace upstream of the coking unit to heat the feedstream to a predetermined coking temperature; g. introducing the hot feedstream into the coking unit; and h. recovering a coking unit product stream that is free of catalyst and forming a coke product that contains the catalyst.

Implementations of the present disclosure relate to a method of operating a coker unit comprising the steps of: collecting a coker-furnace feed stream; introducing the coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; and introducing a hydrogen-donor gas into either or both of the coker-furnace feed stream or the coker-drum feed stream.

The invention presents a covered cavity kiln pyrolyzer with modulated means of rotation, to promote mixing and exposure of the biomass to heat, thereby allowing complete and efficient pyrolysis of biomass therein. The invention has a portal arrangement for simultaneous entry of fuel and air alongside the exit of emissions and flames to a separate hood structure. In addition to rotational modulation for mixing, the rotational capabilities of the kiln also permit the removal of processed charcoal when the portal is turned downward. The invention also has a system of internal prongs for mixing and sifting removal of char, as well as automated fuel delivery mechanisms and a system of openings to allow insertion of pipes and sensors into the kiln for monitoring and for additional delivery of reagents for better modulation and efficiency by a user during the pyrolyzation process.
