SYSTEMS AND METHODS FOR REFINING COAL INTO HIGH VALUE PRODUCTS

摘要

Described herein are integrated thermochemical processes for the conversion of coal into high-value products using a combination of pyrolysis and solvent extraction. The described systems and methods are versatile and may be used to generate a variety of high value products including chemicals (aromatics, asphaltenes, napthenes, phenols, polyamides, polyurethanes, polyesters), polymer composite products (resins, coatings), graphitic products, agricultural materials, building materials, carbon fiber and other products that are substantially more valuable that the energy generated via combustion. Further, these systems and methods are specifically designed to be highly branched and highly flexible, allowing for a high selectivity and optimization for increasing the value of the products relative to the feedstock.
