Sugarcane bagasse is available in plenty in and around communities of almost all major and minor places of India. Among all the potential lignocellulosic sources of biogas production sugarcane bagasse was selected for this study related to enhancement of biogas production and minimization of retention time. It was clearly observed that biogas generation response from sugarcane bagasse treated mechanically (A) was maximum both in terms of production rate and ultimate yield of biogas. Alkaline (B) and acid (C) treatment also led to biogas production but their corrosive effect on the sample might have been the possible reason for being less effective in enhancement of biogas yield as compared to that of mechanical treatment. The maximum ultimate yield of biogas was 308.7 ml/gVS (A) followed by 272.6 ml/gVS and 240.2 ml/gVS respectively.Keywords

It is well known that Coal is an important fossil fuel and is used as a major source of energy in power plants and blast furnaces, but minerals in coal inhibit the effective utilization of coals. These are kind of troublesome materials in the cumbustors by forming the ash during combustion of coal. Industrial demand of coal with minimum ash content so that it can be efficiently used in metallurgical process, or, power plants. This paper reviews the removal of ash-forming minerals of coal using solvents by chemical techniques. Solvents, like N-Methyl-2-pyrrolidone (NMP), 1-methyl naphthalene (MN), Dimethylformamide (DMF), Dimethyl sulfoxide (DMSO) can be used to reduce the ash content of coal. However, polar solvents have been proved to extract greater amounts of coal and reduce ash to a greater extent than non-polar solvents, particularly for lower rank or sub-bituminous coals. However, if non-polar solvents are used, then traces of polar additives can also increase the extraction of coal as well as cause greater reduction of the ash content. The degree of ash reduction depends not only on the solvent used, but also on the extraction temperature, time and rank of coals.Keywords
