The present study was carried out to utilize the groundnut shell biomass for bio-oil production which has significant use in commercial sectors for eco-friendly green fuel and chemical generation. Spouted bed reactor was designed and developed for the production of bio-oil under various temperatures. Properties of the bio-oil were found by standard procedures. Compositional analysis of bio-oil was done by GC-MS and FTIR methods. Optimized production (40.7 %) of biooil was obtained at 550 °C temperature. Heating value of the bio-oil was found to be 21.5 MJ kg-1. Chemical compounds such as phenols, amines, amides and acids were reported in the analysis. The obtainedbio-oil can be used as fuel in transportation sector after upgradation and the derived chemicals have potential applications in pharmaceutical and resin industries

Activated carbon was produced from coconut shell through chemical activation using phosphoric acid. The optimization of process parameters namely activation temperature (400-700 °C), time (30- 120 min) and impregnation ratio (0.5-3:1) was carried out using L16 Taguchi design with iodine number as a response variable. Sixteen experiments were performed at the conditions given by the Taguchi design and their corresponding iodine number was estimated. The optimized conditions for phosphoric acid activation were found to 600 °C, 60 min and 2:1 impregnation ratio with the iodine number of 1230 mg g-1.Activation temperature was the most influential factor on pore characteristics of activated carbon followed by impregnation ratio and time. The study inferred that phosphoric acid can be an effective activating agent for the production of porous carbons.
