Study of Conversion of Peanut Hulls to Solid Biofuel

Abstract

The shortage of oil and the ever-increasing pollution are forcing countries to diversify their means of energy production and in particular to think of renewable energies. In this study we are interested in the production of solid biofuel from peanut shells by heat treatment. The study of the combustion properties using thermogravimetric analysis under oxidizing atmosphere showed us that the combustion behavior of the raw biomass differs from its biochar, compared to its raw biomass, the biochar has good characteristics of combustion and high energy content. The calorific value has increased significantly from 12 to 21 which offers the biochar important combustion properties.
