Processes for the production of coke, and one or more volatile products comprise the steps of: (i) providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% v of the particles are no greater than about 100 ?m in diameter; wherein the PCP has an ash content of less than about 10% m and a water content of less than around 5% m; (ii) combining the PCP with a liquid residue oil to create a combined solid-liquid blend, wherein the solid-liquid blend comprises at least around 0.1% m and at most around 30% m PCP; (iii) subjecting the solid-liquid blend to a temperature in excess of 375? C. for a time period sufficient to induce cracking of at least 1% of the PCP particles to generate the one or more volatile products, and (iv) producing coke from the product of step (iii).

Some variations provide a process for producing biocarbon pellets, comprising: pyrolyzing a biomass-containing feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a pyrolysis vapor; introducing the pyrolysis vapor to a separation unit, to generate a pyrolysis precipitate in liquid or solid form; contacting the first biogenic reagent with the pyrolysis precipitate, thereby generating an intermediate material; pelletizing the intermediate material, to generate intermediate pellets; optionally, drying the intermediate pellets; separately pyrolyzing the intermediate pellets in a second pyrolysis reactor to generate a second biogenic reagent and a pyrolysis off-gas; and recovering the second biogenic reagent as biocarbon pellets. Some variations provide a similar process that utilizes a carbon-containing condensed-matter material, which is not necessarily a pyrolysis precipitate. The disclosure provides improved processes for producing biocarbon compositions, especially with respect to carbon yield and biocarbon properties, such as reactivity.

Systems and methods are provided for reducing or minimizing the chloride content of products generated during co-processing of a plastic feedstock (such as plastic waste) in a refinery process. The reduction in chloride is achieved by mixing the plastic feedstock with one or more additional feedstocks for co-processing in a mixing and/or holding vessel that is maintained at a dechlorination temperature that allows for decomposition of chlorine from the plastic feedstock to form HCl, while reducing or minimizing other conversion of the plastic feedstock and/or the additional feedstock. A purge gas can be passed through the mixing/holding vessel to remove the evolved HCl from the vessel. Because the dechlorination temperature is selected to reduce or minimize conversion of the feedstocks in the mixture, the amount of carbon-containing products that are removed with the purge gas can be reduced or minimized. The dechlorinated mixture of plastic feedstock and additional feedstock(s) can then be processed in a convenient refinery process, such as a thermal cracking process (e.g., coking, visbreaking, other types of pyrolysis) or a catalytic conversion process (e.g., fluid catalytic cracking).

A method of producing a hydrocarbon fuel from a soapstock includes supplying a pyrolysis reactor that includes a microwave absorbent bed susceptible to microwave irradiation, applying microwave energy to the pyrolysis reactor, wherein the microwave absorbent bed converts the microwave energy to thermal energy, supplying the soapstock to the microwave absorbent bed, and condensing a vapor generated by pyrolysis of the soapstock sufficient to collect the hydrocarbon fuel.

Aspects of the present disclosure relate to methods, systems, and apparatus for efficiently reducing carbon footprints in refining systems and petrochemical processing systems. In one aspect, a plastic powder feedstock is blended into a feedstock of a processing system to re-use plastic and reduce carbon footprints. In one implementation, a method of blending plastics into a processing system includes pulverizing a plastic supply to a plastic stock having a granule size that is within a range of 7 nanometers to 10 nanometers. The method includes separating the plastic stock to remove a portion having a granule size that is outside of the range of 7 nanometers to 10 nanometers and generate a plastic feedstock. The method includes blending the plastic feedstock into a feedstock of the processing system to generate a blended feedstock, and processing the blended feedstock.

Coke including additives that are accumulated at the yield points or in the regions surrounded by the yield points. For homogeneous distribution, the additives are continuously dosed into the delayed coker during the filling time. The dosing can be carried out by powdery blowing with an inert gas (nitrogen) or also distributed in a slurry consisting of the reaction components and a partial flow of the coker feed (vacuum resid, pytar, decant oil or coal-tar distillates). According to an advantageous form of embodiment, the additives may optionally have a diameter of between 0.05 mm and 5 mm, preferably between 1 mm and 3 mm. Advantageously, the additives can be selected from at least one of acetylene coke, fluid coke, flexi coke, shot coke, carbon black, non-graphitisable carbons (chars), non-graphitic anthracite, silicon carbide, titanium carbide, titanium diboride or mixtures thereof.
