Bioethanol can be used as a second generation advanced biofuels. Currently it is mainly produced from starch but bioethanol production from starch leads to competition for food, land and price. Therefore, ligno-cellulosic agricultural residues are potentially used for bioethanol production to solve such challenges. The efficiency of the fermentation process mainly depends on the amount of reducing sugars which is further enhanced by selecting an efficient pre-treatment process. In the present work Tamarind seeds have been chosen as the substrate. The yield of bioethanol mainly depends on the yield of reducing sugars which is again dependent on the various pre-treatment methods used. So, the proposed work aims to carry out different pre-treatment methods to identify the best pre-treatment method for enhancing the yield of reducing sugars. The tamarind kernel powder will be extracted from tamarind seeds and the extracted tamarind kernel powder is subjected to various pre-treatment methods like acid pre-treatment, alkaline pre-treatment and steam explosion. The amount of reducing sugars obtained, were then determined by di-nitro salicylic acid method. It was found that acid pre-treatment with 0.3N HCl and 0.3N H2SO4 is the best pre-treatment method among the selected pre-treatment methods.

Catalytic converters are used to convert harmful exhaust gases like CO, NOx and unburnt hydrocarbons released by internal combustion engine of automobiles into less harmful gases like CO2, H2O and N2. During the start-up of engine run, catalytic converters suffer cold start problems as the catalyst does not remain active in cold conditions. This results in emission of unconverted harmful gases into the atmosphere. This work attempts to eliminate cold start problems using a heat storage system to keep the catalytic converter hot even under engine off conditions. A eutectic alloy of Mg-Zn-Al is used as the Phase Change Material (PCM) to store the heat around the catalyst. This alloy has high latent heat of fusion, high specific heat, suitable melting point and high thermal stability. Mg-Zn-Al eutectic alloy changes its state between liquid and solid on application and removal of heat. Thus this phase change material acts as a heat storage mechanism in the catalytic converter. Catalytic converter design also involves Rockwool insulation in order to aid longer heat storage. This thermal energy storage system as a combination of PCM and insulation, keeps the catalytic converter hot for several hours even after the engine is shut ofReduction of cold start emissions in automotive catalytic converter using the...
