The invention relates to a pyrolysis method for recovering at least one component from a feedstock material using a thermal treatment. The feedstock material is delivered to a pyrolytic chamber (1), exposed to a controlled atmosphere, and heated to a treatment temperature of the at least one component in the pyrolytic chamber (1) by applying microwave energy. The pyrolysis breakdown products are separated by fractional condensation and a targeted component is decomposed in microwave plasma. The microwave plasma is generated such that plasma temperature is varied over a temperature range including a decomposition and/or cracking temperature of the at least one component.

The present invention relates to a novel process with lower recycle ratio while eliminating the need for quench column for production of superior quality coke conforming to specifications of anode grade coke. The process of the present invention enables production of lower amounts of coke and fuel oil yields.

Processes and systems for pyrolysing a hydrocarbon. In some examples, the process can include mixing a cooled hydrocarbon effluent and a cooled de-coking effluent to produce a combined effluent. The combined effluent can be introduced into an inlet conduit of a separator under conditions that provide >80 wt. % of the plurality of coke particles with a Stokes number of >10. From a first exit conduit of the separator >55 wt. % of the plurality of coke particles in the combined effluent can be removed, and from a second exit conduit of the separator a coke-lean hydrocarbon effluent that includes <45 wt. % of the plurality of coke particles in the combined effluent can be removed. The first exit conduit and the second exit conduit can be coupled to the inlet conduit.

The delayed coking method includes directing a heated secondary feedstock, which contains heated primary feedstock and recirculate, from a reaction furnace to a coking chamber. Vapor-liquid coking products formed in the coking chamber are then directed to a fractionation column, which fractionates hydrocarbon gas, gasoline, light and heavy gas oils, and bottom residues. Heavy gas oil from the fractionation column is directed to a thermal cracking furnace, the products of which are cooled by cooled light gas oil and directed to an evaporator for separation. In the evaporator, gases and light boiling products are removed by evaporation and returned to the fractionation column, and the remaining distillate cracking residue is separated and used as a component of the recirculate, along with bottom residues from the fractionation column. The resulting process produces high quality and high yield needle and anode cokes.
