TG-FTIR ANALYSIS OF CO-PYROLYSIS OF RICE HUSK AND LIGNITE
摘要
Abstract
TG-FTIR was used to analyze the co-pyrolysis process of rice husk and lignite. It was found that the co-pyrolysis mass lost were larger than mono-pyrolysis, especially when mixed ratio of rice husk and lignite was 2 : 8. The co-pyrolysis products component changed, with CO2 increased, CH4 decreased, CO increased a little, while other organic compounds like phenols, carbonyl compounds, and aromatic compound all decreased a little. The mechanism of co-pyrolysis process was investigated. The metallic oxide in biomass could restrain the process of coal bond into coke so biomass and coal co-pyrolysis process took place the synergistic effect; thus it contributes to the further decomposition of coal. In addition, the biomass generates H2 earlier than coal during co-pyrolysis, and the condensation reaction of coal at high temperature is inhibited because of H2; so the prolysis of coal is promoted.关键词
