Biological upgrading of coal liquids. Quarterly report, January 1, 1994--March 31, 1994
A biological process for upgrading of coal liquids would offer significant advantages, such as operation at ordinary temperature and pressure with better energy efficiency. Of greater importance is the fact that microorganisms do not require an external supply of hydrogen for heteroatom removal, obtaining the required hydrogen from water. Furthermore, the biocatalysts are continuously regenerated by growth on the heteroatom compounds. Ring structures are degraded as the heteroatoms are removed. The heteroatoms are in an innocuous form, such as NH{sub 3}, SO{sub 4}{sup =}, CO{sub 2} and H{sub 2}O. Therefore, there is significant potential for the development of an economical biological process for upgrading coal liquids. This report describes experiments to screen known bacteria and develop isolates for N, O and S removal and aromaticity reduction.
