Labor Management System in Fushun Coal Mines under

2018-9-12  4 The coal seam of Fushun coalfield has been thick so far to a degree that Japanese engineers had never witnessed. Because coal mine technology in mainland Japan could not be applied, SMR independently developed a coal mining technology suitable for the Fushun coalfield. 5 In modern China, the contract system was seen too widely. For that reason, Japanese researchers

Elucidation of Mechanisms Involved in Acid

2019-5-26  Furthermore, most Mg 2+ and Ca 2+ ions could be removed from the coals with acids between 0.01 and 0.1 M. Thermogravimetric analyses showed that the acid-treated coal yielded a weight loss similar to that of raw coal. Thermal decomposition of acid-treated coals cannot play a significant role in the increase in extraction yield that is obtained with polar solvent.

In this paper, we discuss the impact of the rank of coal, petrographic composition, and physico-chemical coal properties on the release and composition of syngas during coal gasification in a CO2 atmosphere. This study used humic coals (parabituminous to anthracite) and lithotypes (bright coal and dull coal). Gasification was performed at temperatures between 600 and 1100 deg;C.

Coal solvent extraction is a clean coal technology that involves the extraction of organic matter from coal using solvents. In this study, the effects of various coal and solvent properties on extraction yield were studied and their correlations were observed. Solvent extraction was performed for fifteen coal samples of different ranks with eight solvents under mild conditions.
