چکیده انگلیسی
Pre-combustion microbial desulphurization of coal containing total sulphur (3.90%) and pyritic sulphur (2.80%) has been evaluated in a coal slurry reactor. The coal slurry reactor operated at hydraulic retention time (HRT) of 96 h with a coal pulp density of 15 percent and remove 79 percent of pyritic sulphur and 76 percent of ash with an increase in the calorific value of coal from 4400 to 6800 kcal kgâ1 at a pyritic load of 1.9 kg pyritic sulphur kgâ1 MLSS dâ1. The treated coal yield is 72 percent. The biochemical kinetic coefficients, viz. yield coefficient (Y) and decay coefficient (Kd) in the coal slurry reactor system are 0.178 and 0.007 dâ1, respectively, while maximum growth rate (μmax) and half saturation rate constant (Ks) are 0.025 hâ1 and 0.220 g lâ1 as pyrite, respectively.
