Biological upgrading of coal liquids. Quarterly report, July 1, 1993--September 30, 1993
Denitrifying and sulfate reducing bacteria are being developed as additional isolates capable of removing sulfur and nitrogen from coal liquids and the model compound naphtha. Both types of bacteria are anaerobic, which during heteroatom removal, should result in less destruction of the carbon in the coal liquids. Denitrifying bacteria grow on alternative carbon sources and should use the sulfur in coal liquids as their sole source of nitrogen. It is estimated that the bacterial cells containdoi:10.2172/10117686 fatcat:a7gk3midfrgtheg64behrni7rq
