Abstract

In this present study an attempt has been made to carry out the investigation on microbial Ash removal of coal using an acidophilic, sulphur oxidizing bacterium, Thiobacillus ferrooxidans in three different laboratory equipments. For this purpose, high sulphur coal has been obtained from Assam (India) and subjected for proximate and ultimate analysis to ascertain various constituents such as ash percentage, moisture content, volatile matter and C, H, N, S percentage present in the coal. Further coal sample was subjected for bio oxidation was carried out in three different laboratory equipments such as Shake flasks, Bioreactor, and Pachuka tank. The experiments were carried out for a period of 25 days at 300 C with initial pH 2.5 with 2% pulp density. From the studies it was possible to reduce a maximum of 26.55 % Sulphur, 18.65 % Nitrogen and 70.3 % Ash in Shake flask studies. A maximum reduction of 29.65% of Sulphur, 63.81 % of Nitrogen and 56.89 % of Ash was observed in studies carried out using a Bioreactor.Similarly, a reduction of 28.15 % Sulphur, 21.46 % Nitrogen, and 52.01 % Ash was obtained in Pachuka Tank tests.
