    The Flexicoking process, developed by Exxon Research and Engineering Company, is, in fact, a fluidized bed coking process that is operated in a unit including a reactor and burner, often referred to as a heater, also including a gasifier for gasifying the coke product by reaction with an air-steam mixture to form a low heating value fuel gas. The heater, in this case, is operated with an ...

  • Difference Between Coal and Coke | Compare the …

    14.05.2012· • Coke is produced from bituminous coal. • Coke burns with no smoke whereas coal burns with smoke. Therefore, coke is better as a fuel than bituminous coal itself. • Therefore, coke is used as a substitute for coal in domestic environments. • Water content in coke goes t zero at the end of the coking process, but coal contains water.

  • Coke Manufacturing - IFC

    In the coke-making process, bituminous coal is fed (usually after processing operations to con-trol the size and quality of the feed) into a series of ovens, which are sealed and heated at high temperatures in the absence of oxygen, typically in cycles lasting 14 to 36 hours. Volatile com- pounds that are driven off the coal are collected and processed to recover combustible gases and other by ...

  • 12.2 Coke Production - US EPA

    Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 ...

  • Carbonization of Coal for Metallurgical Coke …

    The coal to coke transformation takes place as the coal is heated. When the state of fusing is reached, the layer of heated coal softens and fuses. From about 375 deg C to 475 deg C, the coal decomposes to form plastic layer. Destructive distillation reactions proceed rapidly in the plastic layer with evolution of volatile products. At about 475 deg C to 600 deg C, there is a marked evolution of tar, and …

    A typical coke manufacturing process is shown schematically in Figure 12.2-2. Coke manufacturing includes preparing, charging, and heating the coal; removing and cooling the coke product; and cooling, cleaning, and recycling the oven gas. Coal is prepared for coking by pulverizing so that 80 to 90 percent passes through a 3.2 millimeter (1/8 inch) screen. Several types of coal may be blended ...

  • What Is the Difference Between Coal and Coke …

    Coke is a byproduct of bituminous coal. When coal undergoes a process known as destructive distillation, it converts to coke. This process entails heating the fuel at a high temperature with no oxygen. The impurities and flammables burn off when coal changes to coke, and the result is a dull, porous substance with high carbon content.
