Estimating the term…
Described herein are integrated thermochemical processes for the deliberate decomposition, extraction and conversion of coal into high-value products and goods via solvent extraction, chemical reaction and/or separation. The described systems and methods are versatile and may be used to generate a variety of intermediate, derivative and finished high value products including chemicals (aromatics, asphaltenes, naphthalenes, phenols and precursors for the production of polyamides, polyurethanes, polyesters, graphitic materials), polymer composite products (resins, paints, coatings, adhesives), agricultural materials, building materials, carbon fiber, graphene products and other materials that are substantially more valuable that the energy generated via combustion.
A method of processing a coal-based feed stock to make a high value product, said method comprising:
The method of any of claims 1-3, wherein said coal-based feedstock is generated by thermal treatment of coal or a derivative thereof.
The method of 23, wherein said partial precipitation, fractional crystallization, or fractional freezing is carried out via flash precipitation.
The method of any of the proceeding claims, wherein said high value products are non-fuel products.
The method of any of the proceeding claims, wherein said high value products are one or more of:
The method of any of the proceeding claims, wherein said high value products are polyurethanes, polyamides, polyesters, epoxy polymers or precursors thereof.
