摘要

Analysis of an aromatic fraction from a coal tar produced from an underground coal gasification test shows mostly methylated naphthalenes, anthracenes, and phenanthrenes. The similarity between various aromatic fractions and the corresponding similarity of acid, base, and aliphatic fractions suggests that the liquid product is very constant in composition with respect to time. This would in turn indicate that the LVW process approaches steady state conditions. The constancy of such a product would certainly be compatible and desirable with any facility that might utilize such a liquid for either a feedstock or as a fuel. The lack of evidence for any PNA's in the aromatic fraction is certainly encouraging from an environmental standpoint and would probably be expected when considering the way in which the coal tar is produced. As a by-product, the coal tar appears to be a desirable product which only enhances the outlook for underground coal gasification becoming a commercial process. (ERA citation 02:055561)
