含油污泥与玉米秸秆共热解协同特性
Synergy effect during co-pyrolysis of oily sludge and corn stalk
摘要
Abstract
The co-pyrolysis characteristics of oily sludge and corn stalk were investigated by thermogravimetric analysis coupled with Fourier transform infrared spectrometer (TG-FTIR).And the synergistic effects of each temperature section was analyzed.TG results showed that the co-pyrolysis could be divided into three main stages,corresponding to volatiles release (210 to 520 ℃),decomposition of carbonate (600 to 780 ℃),decomposition of heavy oily substance and gasification of chars (900 to 1 100 ℃).And different synergistic effects appeared in different pyrolysis stages.The kinetics analysis showed that the activation energy of the first stage increased,and the activation energy of the second and third stage decreased greatly.FTIR spectroscopy indicated that the co-pyrolysis products were consistent with the products of individual fuels at the first and second stage,but co-pyrolysis lead to decomposition and conversion of methyl compounds at the third stage.Co-pyrolysis could promote the precipitation of CO2,CO,CH4 and C=O compounds.When 10% corn stalk added,the precipitation of CO2,CO and CH4were promoted to the highest extent,and adding 30% corn stalk was more beneficial to the precipitation of C=O compounds.关键词
