Pellets de bagaço de cana-de-açúcar e de cana energia com adição de agente aglutinante e tratamento por torrefação

Abstract

ABSTRACT

Biomass is one of the most promising sources of clean and sustainable energy generation that exists. Brazil is a country with great potential for generating this type of energy due to its vast territorial area and immense variety of biodiversity. The cultivation of sugarcane is widespread in the country, producing sugar, alcohol and energy through the burning of sugarcane bagasse. However, this energy generation is inefficient due to the high ash content that drastically reduces energy efficiency. In this work, common sugar cane and energy cane bagasse pellets were developed, the energy properties were evaluated with the addition of 5% of residual cooking oil as a binding agent and also the treatment by roasting at 230 °C, in order to to obtain a product with greater density, and the analyzes carried out on the common sugarcane pellets were compared to the energy cane pellets. Energy cane pellets had higher calorific value than common sugar cane pellets and both had a significant increase in energy efficiency with the addition of residual cooking oil as well as with the roasting process. The addition of residual cooking oil also reduced the ash content, presenting great potential as a binding agent, improving the energy properties of sugarcane bagasse pellets, making them more efficient.
