The current status of the depletion of oil reserves and increase their prices, the use of biomass has gained interest in fuels and chemicals. Pyrolysis is one of the new technologies for converting biomass to energy and chemicals through thermochemical biomass route. One such chemical, derived from lignocellulosic biomass, with the potential to replace petroleum-derived chemical "phenol" (substituted phenols, phenols and derivatives) sugar cane pulp and cashew shells two such biomass, are abundant in India. India is the largest producer of cashew nuts while ranks second in production of sugar cane in the world. The pyrolysis of biomass, liquid known as "bio-oil" produced together with char and gases that have fuel applications. the recovery process of phenol-rich oil, having up to 72 \% phenols and substituted phenols from pyrolysis oils oilseeds and production of Cardanol oil-rich (with 85% concentration Cardanol) from pyrotechnics based on cashew nut shell liquid (CNSL) and by using supercritical fluid extraction has. These oils are of industrial importance-specially in the resin and laminate industry. Balance available after extraction of the oil can be used as a solid fuel. a simple mathematical model was proposed to predict the yield of biomass. The same model has been extended to the economic evaluation for extract derived from liquid samples. Optimum extraction for extracts from both sugar cane bagasse and cashew pyrolysis liquid was assessed. Good cost and profit analysis through the proposed model provides internal rates of return 18% and 26% for extracts, obtained from sugar cane husks and cashewnut shell pyrolysis oils, respectively.
