采用热重分析仪、填充床反应器、傅里叶变换红外光谱仪和气相色谱仪研究了石化废水污泥与霍林河褐煤的共热解特性。比较了不同污泥掺混比下混合污泥的热解特性。热重实验表明，共混物之间的相互作用有利于生成更多的残留物。在填充床反应器中，协同效应促进了气体产物的释放，而液体和固体产物的残留量比加和方式计算的少。傅里叶变换红外光谱分析表明，随着热解温度的升高，煤焦中的主要官能团逐渐消失，热解过程中挥发分中出现了H2O、CH 4、CO和CO2。气体组成分析表明，随着热解温度和污泥掺混比的增加，H2-和CO的产率明显增加，而CH 4和CO2的产率变化相对复杂。(C)2016爱思唯尔有限公司版权所有
Co-pyrolysis characteristics of petrochemical wastewater sludge and Huolinhe lignite were investigated using thermogravimetric analyzer and packed-bed reactor coupled with Fourier transform infrared spectrometer and gas chromatography. The pyrolysis characteristics of the blends at various sludge blending ratios were compared with those of the individual materials. Thermogravimetric experiments showed that the interactions between the blends were beneficial to generate more residues. In packed-bed reactor, synergetic effects promoted the release of gas products and left less liquid and solid products than those calculated by additive manner. Fourier transform infrared spectrometer analysis showed that main functional groups in chars gradually disappeared with pyrolysis temperatures increasing, and H2O, CH4, CO, and CO2 appeared in volatiles during pyrolysis. Gas compositions analysis indicated that, the yields of H-2 and CO clearly increased as the pyrolysis temperature and sludge blending ratio increasing, while the changes of CH4 and CO2 yields were relatively complex.
