STUDY ON PYROLYSIS CHARACTERISTICS OF CORN STRAW
IntroductionCurrent energy consumption of biomass accounted for about 14% of total world energy consumption, second only to coal, oil, and natural gas, and developing countries accounted for 75% of the biomass utilization 1, 2. Increasing the use of biomass for energy generation purposes is of particular interest nowadays because they allow mitigation of greenhouse gases and provide means of energy independence 3. The pyrolysis, basically a polymeric structure cracking process, converted the lignocellulosic materials into volatile fraction and char. The volatile fraction (gas or liquid, depending on its molecular weight) can be used as a fuel or as a chemical synthesis source. On the other hand, the solid fraction presented several applications, like as a domestic fuel, in the production of activated carbon, or as a reducing agent in metallurgy 4, 5. Understanding pyrolysis characteristics was important for the effective design and operation of the thermochemical conversion units. It was always a fundamental step for these conversion processes. Thermoanalytical techniques, in particular thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG), allowed this information to be obtained in a simple and straightforward manner. The objective of this study was to investigate the pyrolysis characteristics of different parts of corn straw.
