The global energy crisis arouses growing interest in the field of renewable energy all over the world. Biomass is a world-recognized environmentally friendly renewable energy because of its lower contents of N and S element and the approximate zero net emissions of CO2. How to make full use of biomass energy has been an important direction of studies in the field of renewable energy.
