摘要

利用有机固废替代化石燃料的共热解技术，在降低煤炭消耗和资源高效利用方面具有双重价值。为将传统生物质/塑料-煤二元混合体系拓展至生物质-塑料-煤三元混合体系，借助TG-MS联用仪研究了烘焙生物质（稻壳、玉米秸秆）和聚乙烯塑料（PE）与烟煤（BC）的共热解特性及动力学。结果表明，烘焙可显著提高生物质的碳含量，改善其热解特性。在BC与固废组成的二元混合物共热解中，引入烘焙玉米秸秆（HC）或PE都能促进BC热解，也可增大可燃气体（H

、CH

和CO）释放量，而添加烘焙稻壳（HR）则抑制了可燃气体生成。对于三元混合物，BC-HC-P（P代表烘焙后PE）共热解产生的协同效应远强于BC-HR-P，其协同指数最大值为4.73%，并且BC-HC-P共热解可释放更多H

。通过Coats-Redfern法发现BC-HC和BC-HC-P在共热解第二阶段的活化能和平均活化能分别为91.07 kJ/mol和111.23 kJ/mol。

Abstract

The co-pyrolysis technology that uses organic solid waste to replace fossil fuels has dual value in reducing coal consumption and promoting efficient utilization of resource. To extend traditional biomass/plastic-coal binary mixed system to biomass-plastic-coal ternary mixed system

the co-pyrolysis characteristics and kinetics of torrefied biomass (rice husks

corn stalks) and polyethylene plastic (PE) with bituminous coal (BC) were studied by TG-MS coupling instrument. The results show that torrefaction can significantly increase the carbon content of biomass and improve the pyrolysis characteristics. In co-pyrolysis of binary mixtur

es composed of BC and solid wastes

the addition of torrefied corn stalks (HC) or PE can not only promote the pyrolysis of BC but also can increase the release amounts of combustible gases (H

and CO)

while the addition of torrefied rice husks (HR) can inhibit the generation of combustible gases. For the ternary mixtures

the synergistic effect produced by co-pyrolysis of BC-HC-P (P represents torrefied PE) is much stronger than that of BC-HR-P

with the maximum synergistic index of 4.73%

and the co-pyrolysis of BC-HC-P can release more H

. It is found through the Coats-Redfern method that the activation energy and average activation energy of BC-HC and BC-HC-P in stage two of co-pyrolysis are 91.07 kJ/mol and 111.23 kJ/mol

respectively.
