In the case of highly swelling coals, addition of diluents to improve results was found unsat- isfactory because their effect is not linear and is not the same for different coals. The addition of increasing amounts of . The merit of the synthetic coking coal lies in that charac-teristics of whatever kind one may desire is obtainable by selecting conditions for preparation and original materials. 1 Introduction. This paper is dealt with the characteristics and the properties of synthetic coking coal (Man Made Coking Coal) through the processing and.
a comparison swelling coal properties. A rough pulverized grind of Utah Blind Canyon hvC-bi- tuminous coal was obtained from the Hunting- ton Power Plant. A size-classified Pittsburgh No. 8 hvA-bituminous coal was obtained from the PETC Direct Utilization/AR & TD suite of coals (PSOCD), and is the same coal. The gas-induced swelling behavior of coal is important when considering CO 2 sequestration into coal seams or enhanced coalbed methane applications, but coals may also swell in the presence of moisture, or shrink on drying. In this paper we examine the moisture-swelling properties of coals . shown in Table 2. There are nine bituminous coal types presenting caking properties, including PS, SM, JM, 1/3JM, FM, QF, QM, 1/2ZN and RN. In addition to the volatile matter values, GB employs three caking properties to distinguish the different bituminous coal types. These caking properties include. Bituminous type coals have just 2 subtypes call steam coal / thermal coal & metallurgical coal. Metallurgical coal also called coking coal is coal that is baked in ovens in complete absence of oxygen and at great temperatures as high as °F. This type of process is what is called pyrolysis.
Plastic waste recycling represents a major challenge in environmental protection with different routes now available for dealing with mechanical, chemical, and energy recycling. New concepts in plastic waste recycling have emerged so that now such wastes can be used to replace fossil fuels, either as an energy source or as a secondary raw material. Our objective is to explore the modification. plastic coals and weakly coking coals with temperature ranges overlapping its own. The Gieseler ratios deduced in this work from Gieseler parameters, also confirm the coal as prime coking and thus suitable for metallurgical cokemaking. REFERENCES. 1. Afonja, A.A “New Techniques of Low Coking Coal Utilization in the Blast Furnace. Differentiation of coking & non-coking coals: From physical appearance it is very difficult if not impossible to differentiate between non-coking & a coking coal. A non – caking coal is that coal which when heated in the absence of air for e.g. as in the determination of VM, leaves a powdery residue. A non-caking coal is always a non-coking coal. • A very soft bituminous coal suitable for coking (Sci-Tech Dictionary) • a bituminous coal suitable for making into coke (Merriam-Webster) • coal having mean reflectance of more than and swelling Index or CSN of 1 and above (Indian Gov) • Coking coals are those coals that soften, swell and then solidify as they are.
