The effects of moderate coal cleaning on the microbial removal of organic sulfur. [Quarterly] technical report, December 1, 1991--February 29, 1992
The purpose of this project is to investigate the possibilities of developing an integrated physical/chemical/microbial process for the pre-combustion removal of sulfur from coal. Microorganisms are capable of specifically cleaving carbon-sulfur bonds and removing substantial amounts of organic sulfur from coal; however, the removal of organic sulfur form coal by microorganisms is hampered by the fact that, as a solid substrate, it is difficult to bring microorganisms in contact with the entirety of a coal sample. This study will examine the suitability of physically/chemically treated coal samples for subsequent biodesulfurization. During the current quarter, chemical comminution and combined chemical treatment/explosive comminution experiments have been performed to generate coal samples with increased surface area and porosity. Ammonia vapor was found to be the most effective chemical comminution agent and the optimum conditions for combined chemical treatment/explosive comminution have not yet been determined.
