Facile and Economical Preparation of SiAlON-based composites using Coal Gangue: From Fundamental to Industrial Application.
01-03-2021· Coal gangue, as a solid waste generated during coal mining and washing, not only encroaches on a large number of land resources but also poses certain risks to the environment. It is reported that the cumulative amount of coal gangue piled up in China has reached 6 billion tons, and the annual discharge amount is about 500–800 million tons.

11-07-2013· The process of Underground Coal Gasification (UCG) involves the partial burning of coal underground. This produces even more toxic and carcinogenic coal tars including benzene, toluene, ethyl-benzene and xylene. Large volumes of these toxic compounds are brought to the surface by the process. Waste Disposal.
26-09-2015· Glass–ceramic s were fabricated at a relatively low temperature by incorporating coal gangue, waste quartz sand and sintering additives in different proportions. Sintering and the ing behavior of the s were studied using thermal, X-ray techniques and morphological characterization, followed with physical and mechanical properties measurements.
COAL GASIFICATION. 2018-6-28 coal gasification 4.1.1 Experimental systems As reported in IARC Monograph Volume 34 (IARC, 1984 ), coal-gasification samples from the process stream and waste by-products were found to be mutagenic in various strains of Salmonella typhimurium in the presence of an exogenous metabolic activation system.
