Pirólise rápida de casca de soja: desenvolvimento do reator de leito fluidizado, análise do bio-óleo produzido e do vapor obtido na pirólise analítica
Environmental problems and climate changes due to global heating have happened by the emission of carbon dioxide, the gradual decrease of fossil fuels and the energy increasing demand have generated some interest by the development of a fuel safe source; thus the interest by sustainable and renewabl...
