摘要： PURPOSE:To prepare coke and recover tar and gas as by-products in high yields, by depolymerizing coal, recovering the low-MW component thus prepd., and carbonizing or carbonizing the low-MW component after molding. CONSTITUTION:Coal is depolymerized at pref. 300-600 deg.C. The depolymerization product is extracted with, e.g., a solvent such as tetrahydrofuran, to recover a low-MW component. This component is carbonized directly or after molding to prepare coke. When coal is directly carbonized according to the conventional process, there occurs depolymerization. However, most of the depolymerization product brings about re-polymerization to prepare coke. This lowers the yields of tar and gas, particularly tar. According to the present process, since the low-MW component prepared by depolymerization of coal is carbonized after recovery of tar and gas, the re-polymerization of the low-MW component can be prevented, which enhances the yields of tar and gas, particularly tar.

摘要： PURPOSE:To utilize a by-product tar in the manufacture of formed coke through a shaft furnace as a binder for the briquetted coal which is in short supply, by dissolving a bituminous substance having, a specific softening point in the tar simply pretreated. CONSTITUTION:Tar, formed in the carbonization of briquetted coal by direct heating with a high-temperature gas in a shaft furnace, is simply desludged, dehydrated, and heated in briquetting to remove the low-boiling components which distill away up to 200 deg.C and foam the coal in heating, and a bituminous substance having a softening point of 50-400 deg.C is dissolved in the tar and utilized as a binder for the coal. As shown in the figure, the method requires no tar distillation step and is useful for saving energy.

摘要： PURPOSE:To improve operating efficiency and economical advantage, by the addition of hot water instead of steam in blending dried powdered coal with a binder. CONSTITUTION:In blending dried powdered coal with a binder, e.g., coal-tar pitch by a blender under heating, the addition of required amount of hot water at a temperature as high as that of the powdered coal shortens a humidifying period remarkably in comparison with steam spray method and costs for energy and facilities can be reduced.

摘要： PURPOSE:To obtain coke for use in a blast furnace which is excellent in quality and productivity, by providing a produced coke residence chamber connected to an indirect heating vertical continuous dry distillation oven where the quality of the produced coke can be improved. CONSTITUTION:Coal 1 is pulverized with a pulverizer 2 into pulverized coal having a size of 5mm or less and is preheated at 100-400 deg.C in an airborne preheating dryer 3. An indirect heating vertical continuous dry distillation oven 5 is charged with the pulverized coal from a charging port 14 through a storage pin 4. The pulverized coal is dry distilled in a coke oven chamber 10 having an oven width a of 130-250mm through indirect heating with a heat of combustion from a combustion chamber 11 through the medium of a furnace wall 13. The coke 17 thus produced is brought into contact with a dry distillation production fluid for a required time in a coke residence chamber 6, thereby improving the antireacting properties against CO2. The coke 17 is taken out as a coke product 8, while dry distillation production fluid is discharged from a discharging passage 7.
