Incorporating coal as a filler to fabricate polymer composites or as a modifier to enhance the properties of polymeric materials is an important strategy to extend the nonenergy application and sustainability of coal. The literature shows that different process pathways can be used to develop coal/polymer composites owing to different enduses.
vapor extracted from coal particles. A rotating cooler is used to cool coal powder to 50°C. Then cooled coal enters an intermediate vessel and is sent to a silo using a pneumatic conveying duct. Heated air enters the dryer from the left end and exits from the other end and brings the vapor extracted from the coal particles.

Coal powder is kept in a packed bed and the extraction is carried out at 143 bar pressure. Using sulfur as a model heteroatom, extractive efficiency is examined as a function of the temperature, fluid composition, fluid flow, and extraction time. The results indicate that carbon dioxide, water, and supercritical watercarbon dioxide (ScWC) all ...
