    Keywords: coking coal, coking wastewater, adsorption, COD, phenol Introduction Coking wastewater is a type of highly concentrated organic wastewater generated from a process of making coke, purifying coal gas and recovering coke products (Wu and Zhu, 2012). Coking wastewater is a kind of intractable wastewater which is

  • Pretreatment of coking wastewater by an adsorption process

    The kinetics of COD and phenol adsorption from coking wastewater by coking coal fitted the pseudo second-order model. The adsorption process of coking coal can be classified into two categories

  • Adsorption of Surfactants on Coal Surfaces in the Coking

    Coking wastewater, instead of clean water, is used to prepare coking wastewater–coal slurry (CWCS), which can be used as liquid fuel for combustion and gasification. Surfactant adsorption on coal surfaces affects the preparation and industrial application of coal slurry because it is essential for improving the surface wettability of coal.

  • Coking is a refinery process that produces 19% of finished

    Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum coke—a coal-like material. Exports of petroleum coke accounted for about 19% of the nation's finished petroleum product exports through October 2012 with most going to China and other Asian countries.

  • Coke (fuel) Wikipedia

    The industrial production of coke from coal is called coking.The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
