HCM-based opto-electronic and electronic materials. In recent years (Figure 1B), coal has been used as a high-quality carbon-rich precur-sor to derive nanomaterials including graphene quantum dots (GQDs),16,22,23 gra-phene oxide,6,24,25 nanodiamond,26 carbon nanotubes (CNTs),27,28 and more.

Coal upgrading, CCC/156. This report examines current technologies and those likely to be used to produce cleaner coal and coal products, principally for use in power generation and metallurgical applications. Consideration is also given to coal production in the leading coal producing countries, both with developed and developing industries.

A Naomaohu (NMH) coal with high volatile content was used for pyrolysis experiment to afford the thermally gaseous tar. The coal sample was crushed and sieved to 0.25–0.43 mm before being dried at 105 °C under vacuum for 12 hr. Corncob biochar (COBC) produced by pyrolyzing corncob biomass (COB) and Malan (ML) fat coal with …

The invention relates to a rotary kiln low-rank coal pyrolysis cyclic upgrading process, which adopts a rotary kiln to carry out pyrolysis upgrading on low-rank coal to generate high-temperature coal gas containing coal tar and dust and upgraded coke; the high-temperature coal gas is dedusted by two stages of cyclone and then is initially cooled by …
