Biodesulfurization of the Tabas Deposit Coal by Microorganisms

摘要

The results are presented for the investigations of sulfur removal from coal by a mixed culture of microorganisms. Optimal conditions of the process are established (pH, size of coal particles, pulp density, temperature, etc.). They make it possible to reduce the content of pyrite and total sulfur by 91.84 and 53.5percent, respectively. The decrease in ash content of coal under its leaching is noted.
