摘要： The inventions are related to industrial processing of combustible carbon- and hydrocarbon products. A method of processing combustible carbon- and hydrocarbon products is implemented using a reactor equipped with temperature sensors. The reactors comprise the phases of heating the charge (13), pyrolysis of combustible components and coking (12), combustion (11), and formation of a solid residue (4). At the phases of heating the charge (13) and coking and pyrolysis (12), an aerosol (i.e. dust particles and condensed liquid droplets carried away from the combustion zone (11) sorption zone (21) is formed by flushing the upper part of the charge by liquid hydrocarbonaceous products through the dispenser (22) and/or by adding to the batch the solid hydrocarbonaceous products having a softening point above 60° C. and the end boiling point above 300° C. The plant includes a reactor (either of the two aforementioned models), the discharge assembly for discharging of solid and non-combustible by-products (27), the gas-vapor mixture discharge unit (28), a cyclone separator for coarse filtering (cleaning unit for purification and removing the solid and liquid carbonaceous particles) (29), liquid products condensation unit (30), Florence flasks for condensates (31), and liquid hydrocarbon waste tank sump (32). Between the cyclone-type cleaning unit for purification and removing the solid and liquid carbonaceous particles (29) and the liquid products condensation unit (30), there is an additional gas-vapor mixture purification unit (33), consisting of a centrifugal separator for fine purification (34) and one selective-type cyclone (35). The liquid hydrocarbon waste tank sump (32) is equipped with a feed dispenser for their charging to the dispenser (22) located at the upper lid of the reactor (3). The invention allows to improve the quality of purification of the gas-vapor mixture from solid and liquid-drop impurities up to 95%, increase the process productivity and simplify the required hardware design. The invention improves the quality of the gas-vapor mixture purification from solid and liquid-drop impurities for up to 95 percent, increases the process productivity and simplifies the hardware design. 4 independent claims, 16 dependent claims, 4 figures, 3 tables, 3 examples.

摘要： Heavy gas oil components, coking process recycle, and heavier hydrocarbons in the delayed coking process are cracked in the coking vessel by injecting a catalytic additive into the vapors above the gas/liquid-solid interface in the coke drum during the coking cycle. The additive comprises cracking catalyst(s) and quenching agent(s), alone or in combination with seeding agent(s), excess reactant(s), carrier fluid(s), or any combination thereof to modify reaction kinetics to preferentially crack these components. The quenching effect of the additive can be effectively used to condense the highest boiling point compounds of the traditional recycle onto the catalyst(s), thereby focusing the catalyst exposure to these target reactants. Exemplary embodiments of the present invention can also provide methods to (1) reduce coke production, (2) reduce fuel gas production, and (3) increase liquids production.

摘要： A process for producing calcined coke agglomerates characterized by having a low reactivity to carbon dioxide. The process includes calcining green coal agglomerates at a temperature within the range of 1700.degree. F. to 1950.degree. F. (927.degree. C. to 1066.degree. C.) in a calciner. The agglomerates are exposed to a gaseous atmosphere which before cracking contains not less than 20% by volume of at least one straight chain aliphatic hydrocarbon gas containing one to four carbon atoms. The gaseous atmosphere is preheated to a temperature within the range of 200.degree. F. to 700.degree. F.(93.degree. C. to 371.degree. C.) prior to being introduced into the calciner. Carbon produced when the hydrocarbon gas is cracked, is deposited as vitreous carbon on the surfaces, in the fissures and in the pores of the agglomerates. The calcined coke aggglomerates discharged from the calciner have a reactivity to carbon dioxide of between 2% to 8%.
