Phase Composition of Interstitial Clay and Gas Emissions on Heat Treatment
When interstitial clay, which is the waste from shale combustion, is fired at 250°C, the decomposition of organic matter results in the emission of H2, CO, SO3, and CO2 from the ceramic samples. At 350–550°C, the content of oxidant (oxygen) and neutral gas (nitrogen) is markedly less. At 550–750°C, no sharp decrease in their content is observed. At 750–1000°C, the decrease is slight. At 1000°C, mainly CO is formed. At 1050°C, the fired sample contains practically no organic compounds. More complex compounds (anorthite, diopside) are formed, with increase in the mechanical strength.
期刊介绍:
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
