There are two potential energy sources that are needed to sustain life and human development: renewable energy, such as that derived from solar, biomass, and wind energy, and nonrenewable energy, such as coal, petroleum, and natural gas [1–3]. The rapid development of society and gradual reduction of non-renewable energy sources have negatively affected the energy supply of the world. Biomass, which is a renewable energy source, has received considerable research attention because of its wide distribution, large reserves, low cost, and ease of use. The exploitation and application of biomass energy has important economic and environmental benefits to society [4].
