Title: Methods and systems for biological coal-to-biofuels and bioproducts

Abstract

Methods and systems for the biological conversion of pretreated or solubilized coal or waste coal into biofuels. Coal (10) may be pretreated perhaps in a pretreatment reactor (13). Pretreated coal or even solubilized coal may be introduced into a processing reactor such as a bioreactor (16) containing a plurality of microorganisms (9) such as oleaginous microorganisms which can convert at least some of the pretreated or solubilized coal into lipids (19) or biomass (18), which then may be used directly or as a precursor for various products such as biofuels, feedstock, or the like.
