Abstract
Being the main by-product derived from the consumption of green coconut, coconut shell offers attractive potential for use in technologies that use gasification systems integrated with an internal combustion engine in regions where there is a great potential for this residue. In this study, it is proposed to study the incorporation of a cogeneration system with an internal combustion engine aiming at implementation in the Green Coast region, more specifically in the city of Angra dos Reis. Technical analysis was carried out applying the first Thermodynamics Law to determine the energy utilization of the proposed thermal plant aiming at the later evaluation of the performance of a bubbling fluidized bed gasifier for the production of syngas, as well as an economical analyzes in order to check the operational viability of the plant. The study estimated 1786 kg/day of coconut biomass, which provides a potential for generating 107 kWh of electricity. As a result of the technical analysis and overall efficiency of 56% was determined. The cost of electricity produced was estimated at 0.651 R$/kWh, however, the cost of hot water produced was 0.280 R$/kWh. Considering the initial investment of the plant and its amortization over the years, a return on investment of approximately 9 years was estimated
