STUDY ON VOLATILIZATION BEHAVIOR OF GAS COMPONENTS FROM BIOMASS FAST PYROLYSIS

摘要

IntroductionEnergy is directly related to economic development and progress of human society. Faced with the increasing needs from the community, we will cope with energy shortages, together with unreasonable use of encrgy and the serious pollution. With the use and exploration of fossil fuel increases, the impacts on environment will be increasingly serious. We have to find the clean coal utilization technology in such a grim situation. Statistics show that[1], the consumption percentage of fossil fuels as primary energy accounted for 87.21% worldwide in 2002, that for china accounted for 92.92%. However, according to Statistical Review of World Energy in June 2003: the development and use of fossil fuels coal and oil will be depleted on earth in 200 years, 40 years, respectively, and natural gas can only use around 60 years. Moreover, a large amount of coal and oil consumption will induce serious negative environmental effects, such as the greenhouse effect, acid rain, dust and other serious problem.
