摘要

针对废弃含能材料目前的处理方法存在污染大、能量浪费和工艺复杂等问题，基于含能材料热解放热、生物质热解吸热的特性，提出将废弃含能材料与生物质（松木屑）共混热解处理的新思路，实现两者产物高值化的同时，有效利用废弃含能材料中的能量。首先，采用固定床热解反应器探究含能材料与松木屑共热解三相产物的分布及特性。然后，建立Aspen plus共热解模型，考察含能材料与松木屑的共热解的自持性。结果表明：热解气的产率与原料中含能材料占比呈正相关，热解油与热解炭的产率则相反；CO和H

是含能材料与松木屑热解气的主要成分；热解油的主要成分为醛类化合物；当松木屑处理量为500 kg/h，含能材料与松木屑以质量比2:1或1:1的比例共混热解时，有望实现两者的自持共热解，每小时可节约2.00 GJ的能量（约555.56 kW·h）。

Abstract

To address the issues of high pollution

energy waste

and comp

lex processes in current treatment methods for waste energetic materials

a novel approach of co-pyrolysis treatment by blending waste energetic materials with biomass (pine sawdust) is proposed

based on the exothermic nature of energetic material pyrolysis and the endothermic nature of biomass pyrolysis. This approach aims to achieve high-value utilization of their products while effectively harnessing the energy contained in waste energetic materials. First

a fixed-bed pyrolysis reactor was used to investigate the distribution and characteristics of the three-phase products from the co-pyrolysis of energetic materials and pine sawdust. Then

an Aspen plus co-pyrolysis model was established to examine the self-sustainability of the co-pyrolysis of energetic materials and pine sawdust. The results show that the yield of pyrolysis gas is positively correlated with the proportion of energetic materials in the feedstock

while the yields of pyrolysis oil and pyrolysis char show the opposite trend. CO and H

are the main components of the pyrolysis gas from energetic materials and pine sawdust. The primary constituents of the pyrolysis oil are aldehyde compounds. When the pine sawdust processing capacity is 500 kg/h and the energetic materials are blended with pine sawdust at quality ratios of 2:1 or 1:1 for co-pyrolysis

self-sustaining co-pyrolysis of the two materials is expected to be achieved

saving 2.00 GJ of energy per hour (approximately 555.56 kW·h).
