MESOPHASE PITCH FOR CARBON FIBER PRODUCTION USING SUPERCRITICAL CARBON DIOXIDE

Embodiments of methods for improving mesophase pitch for carbon fiber production using supercritical carbon dioxide are described. The methods improve the relative amount and quality of mesophase pitch in feedstocks, such as coal tar, already having at least some mesophase pitch. One particular meth...
