INTER-RELATIONSHIPS BETWEEN HYDROGEN AND CARBON CONTENTS OF BIOMASS FUELS AND THE CALORIFIC VALUES

Abstract

Empirical relationships between hydrogen and carbon contents and the calorific values of rice husks, cotton seeds, jatropha seeds, palm kernel shells and cashew shells were investigated. The experimental data indicated higher correlation coefficient between calorific value and hydrogen content than between calorific value and carbon content, as compared with Tillman predictions. Therefore, the calorific values can be estimated based on hydrogen content of the biomass fuel.
