Methods are disclosed to make coke, graphite, graphene and other materials from biomass derived bio-oil.

The present disclosure relates to a method of producing metallurgical coke from a combination of non-coking and non-metallic carbon-based microwave susceptor. The method is energy efficient, economical, and environmentally friendly. The present disclosure also relates to metallurgical coke having improved coke quality, such as improved coke strength after reaction.

The present invention provides a process for production of graphite coke from an admixture of coal and petroleum-based hydrocarbons. This particularly describes a process wherein a mixture of coal tar pitch and hydrocarbon feedstock such as CLO is purified in a solvent treatment step and the purified mixed feedstock is subjected to thermal cracking to produce high quality graphite/needle coke. This process also provides a synergy in improved coke quality coke formation while using an admixture of coal tar pitch and CLO while subjected to common purification and coking steps.

A composite catalyst for coal depolymerization, the catalyst includes an agent A and an agent B. The agent A includes an iron salt-based catalyst, and the agent B includes a metal salt-based catalyst different from the iron salt-based catalyst. The agent A and the agent B are alternately added during use.

A method for obtaining carbon-containing material from recyclable tires and rubber products, by mechanically crushing a raw material, from recycled tires in a shredder, supplying a charge to a reactor at temperature, removing gaseous pyrolysis products from the reactor, followed by condensing liquid products, unloading solid residue from the reactor and cooling it, feeding the cooled residue into a crusher, coarsely crushing the solid residue, removing metal from the crushed solid residue in a magnetic separator.

A delayed coking process for producing high grade coke comprising: introducing a hydrocarbon feedstock comprising asphaltenes to at least one fractionator to produce at least a bottoms fraction, an intermediate fraction and a light naphtha fraction: passing the bottoms fraction to a delayed coker unit furnace for heating to a predetermined coking temperature; passing the heated bottoms fraction to a first delayed coker unit to produce a first coke product and a first effluent substantially free of asphaltenes and comprising resins; and passing the first effluent to a second delayed coker unit to produce a second coke product comprising the high grade coke.

A coking system comprises the 1st to the m-th heating units and the 1st to the n-th coke towers, each of the m heating units being in communication with the n coke towers, respectively, each of the n coke towers being in communication with one or more separation towers, respectively, in communication with the m-th heating unit and optionally with the i-th heating unit. The coking system can at least utilize petroleum series or coal series raw materials to produce high-quality needle coke with stable performance.

A process for the treatment of a hydrocracking unit bottoms stream containing heavy poly-nuclear aromatic (HPNA) compounds and/or a fresh hydrocracking feedstock stream containing HPNA precursors to produce coke. The HPNA and/or HPNA precursors are removed from the hydrocracking unit bottoms stream and/or a fresh hydrocracking feedstock stream by solvent washing, and the HPNA and/or HPNA precursors are subjected to delayed coking for the production of coke.

Provided is a binder for a coal-containing formed product, which contains a macromolecular polymer having an intrinsic viscosity of 2.0 dl/g or higher.
