Coke for the blast furnace 2. as a chemical reducing agent, it produces gases for. the reduction of iron oxides; and. Metallurgical coke is a macroporous carbon mate 3. as a permeable support, it acts as the only solid. rial of high strength produced by carbonization of material in the furnace that supports the iron.

Chapter 9 Coal to Coke Conversion Ralph Gray Services, 303 Drexel Drive, Monroeville, PA 15146, Summary. This Chapter is principally concerned with the major topics associated with the conversion of coal to coke. Only a limited range of coal rank L£. the bituminous coals, produce acceptable metallurgical cokes.

The process makes the blast furnace reliant on lumpy materials to maintain a gaspermeable stock column. The most important reducing agent is therefore the lumpy coke. Auxiliary reducing agents, such as coal or oil, are injected via the tuyeres. The tasks of coke and coal for the hot metal production and the requirements of the blast furnace on ...

Coal gasification is a process which occurs when coal or char reacts with an oxidizer to produce a gaseous fuelrich product. Integrated Gasification Combined Cycle (IGCC) technology is an efficient and environmentally clean technology for the generation of power from fuel. It is a thermochemical process in which coal is converted

Therefore, it is believed that the radicals determine the coke formation of biooil to a great extend, as the coke is the solid product of biooil thermochemical conversion. Many studies have been done to explore the roles of radicals of coal [ 19, 20 ], coal tar and heavy oil [ 21, 22 ] during the thermochemical conversion processes.

reaction from the gasification reactions serves to preheat the coal before it enters the gasification reaction zone. Consequently, the temperature of the syngas exiting the gasifier is significantly lower than the temperature needed for complete conversion of the coal. Fig. 2.

Carbonization, more narrowly defined, refers to conversion of a starting material into carbon, or a carbonrich solid. It is entirely possible, and indeed often done, to pyrolyze a hydrocarbon feedstock for the purpose of carbonization, but carbonization is not simply pyrolysis by another name.
