Study on the pyrolysis behavior of coal-water slurry and coal-oil-water slurry

Journal of the Energy Institute, 2022
Abstract In this work, different concentrations of coal-water slurry and coal-oil-water slurry were prepared and pyrolyzed at various temperatures of 800–1000 °C. The chemical characteristics and combustion reactivities of chars and the formation mechanism of main gas components of CO, CO2, CH4, and H2 were investigated. With the water content of the

Blended coals for improved coal water slurries

Journal of China University of Mining and Technology, 2008
Three coal samples of different ranks were used to study the effect of coal blending on the preparation of Coal Water Slurry (CWS). The results show that by taking advantage of two kinds of coal, the coal concentration in slurry made from hard-to-pulp coal can be effectively improved and increased by 3%–5% generally.

Rheology of coal-water slurries

Solid Fuel Chemistry, 2009
The costs of preparation and burning of coal slurries, in particular, coal-water fuel (CWF), considerably exceed the cost of coal utilization according to the conventional technology. CWF technology projects suggest that additional expenditures will be compensated for by the profitability of their pipeline transport in the laminar regime.

Study on the slurrying mechanism of coal water slurry prepared from coal gasification wastewater

The Canadian Journal of Chemical Engineering, 2023
Abstract The coal gasification process produces a large amount of wastewater which is seriously polluted and difficult to biochemically treat. The regasification of coal water slurry produced from gasification wastewater meets the requirements of clean and efficient use of energy and the concept of circular ...
