An approach to the calculation of the quantity of heat consumed in the process of coal formation is presented. The variability of this parameter in a coalification series is analyzed using coals from the Kuznetsk and Tunguska Basins as an example....
Thermokinetic analysis of three pitch samples was carried out: coal tar pitch obtained from light coke oven tar (P), mesophase pitch after 10.5 h (MP1), and mesophase pitch after 12 h (MP2) thermopreparation at 410°C. The process was realized in a continuous system with a 10 kg mass...
In order to check the relation between PAHs and dioxins formation, the paper evaluated the possibility of dioxins formation from PAHs via precursor pathway, as well as the corresponding mechanism in municipal solid waste (MSW) incineration process. The incineration experiment mixed proportionally by mun...

The development trend of coal chemical industry is to develop clean coal conversion process,so as to reducing the emission of pollutants.In currently,there have been many studies on the emission of pollutants such as CO2,NOx,SOx,but the ones on PAHs (Polycyclic Aromatic Hydrocarbons) are not en...

Breakdown of this gel is an activated process. At higher and lower concentrations of NMP, free solvent is present. Pyridine also displays ''nonfreezing'' behavior, but it is unclear whether this is due to the formation of a similar gel. At all solvent:coal ratios, a significant amount of...
Coal: It is a sedimentary rock composed of carbon in the maximum amount and also other hydrocarbons. It produces more energy in the combustion process and is used as fuel, and assists in electricity production methods. Answer and Explanation:1 ...
At least the formation of shale gas accumulation me-chanism links the migration, accumulation and accumulation process of coalbed methane (typical adsorption gas reservoir forming principle), source contacting gas (piston type gas water dis-placement principle) and conventional gas (displacement of ...
