Influence of coal properties on coal conversion

2021-2-8  A review was carried out on the influence of coal properties on four main utilization technologies: gasification, carbonization, liquefaction and carbon fibre production. Among several properties rank, type, mineral matter content, distribution of trace elements, structural composition and pore structure were found to be most influential on the behavior of coal during conversion processes.

Change in Properties and Combustion Characteristics

2018-6-7  An Indonesian low-rank coal, Adaro, was hydrothermally treated at 200-350°C in an autoclave. The raw and treated coals have been subjected to several analyses which include hygroscopicity, the content of oxygenic functional groups, FTIR spectrum, and specific surface area. When the coal is hydrothermally treated, the hygroscopicity of coal remarkably decreases.

Influence of coal properties on the CO2 adsorption ...

2018-6-22  The effect of coal properties on CO 2 adsorption would also extend to the gasified chars as the evolution of the char structure is, in turn, a function of the coal properties. From the isotherms presented in Figure 7 (B), it is observed that among the chars at 800°C, sample C char800 has the highest sorption capacity followed by the chars of samples B, D, and A, respectively.

RHEOLOGICAL PROPERTIES OF COAL OIL MIXTURES:

2018-6-13  Coal samples having different ash and moisture contents have been used to study the effect of these components on rheological properties of coal oil mixtures. It has been observed that coals having higher ash content give rise to less viscous coal oil mixtures and viscosity of the COM decreases as moisture content of coal is reduced.

Indonesian Coal Quality and Coal Reserves – Global

2021-6-14  The coal has nil or minimal coking properties, and thus with few exceptions, can only be used as steaming coal. Only some higher-ranking types are also suitable as pulverised injection coal (PCI). The qualities for export generally have a 37–47% share of volatile matter, with 1–10% ash and mostly 15–22% moisture.
