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 96h 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 6800kcalkg...
Investigations were conducted using a low cost support media for microbial attachment and growth for the anaerobic treatment of sugarcane molasses based distillery spentwash employing fixed film reactor (FFR) technology. An HRT of 3 d corresponding to an OLR of 22 kg COD m −3 d −1 based on reactor liquid volume (V L ) (V L = 0.534 V eb , empty bed volume) with...
