title: Pyrolysis of ramie residue: kinetic study and fuel gas produced in a cyclone furnace.
abstract: The thermal decomposition behavior of ramie residue (RR) and the characteristics of fuel gas produced in a cyclone furnace were studied. The pyrolysis kinetics was investigated using thermogravimetric analysis (TGA) at heating rates of 5-20°C/min. The results showed that RR mainly decomposed between 250 and 390°C, and the apparent activation energy ranged from 200 to 258 kJ/mol. In the cyclone furnace, fast pyrolysis, partial combustion and gasification occurred almost simultaneously, and the thermal energy was supplied by partial combustion of RR powder at the hypo stoichiometric amount of air. Higher effect of equivalence ratio (ER) led to higher reaction temperature and fewer contents of tar and char, but too high ER lowered fuel gas content and degraded fuel gas quality. Over the ranges of the experimental conditions, the gas yield varied between 1.07 and 2.08 N m(3)/kg and the LHV was between 3350 and 4798 kJ/Nm(3).
