  • Development Of New Coal Blend Preparation

    preparation of coal blends for carbonization assumes paramount importance in terms of cost, quality, and resource utilization. judicious coal-blending techniques based on intrinsic quality parameters coupled with various precarbonization steps to maintain blend homogeneity, granulometry, caking and coking properties of the blend are practiced many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. for example, Jo considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component and the addition of a suitable amount of caking component are

  • Preparation Of Coke From Indonesian Lignites By A

    production of coke from lignites was studied in continuation of a previous study that demonstrated effectiveness of a sequence of hot briquetting and carbonization on preparation of high strength coke from a lignite. cokes were prepared from four indonesian lignites with or without pretreatments such as hydrothermal treatment at acid washing and a combination of them artificial graphite is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. specific capacity and reversibility is lost at high temperatures from 1000 Ah kg to 150 Ah kg above 2000 an increasing degree of graphitization improves capacity again and minimizes irreversible charge.
