摘要

生物质与塑料、煤等物料之间的共热解是环境友好、具有极大发展潜力的生物质热解升级处理方式。通过自制快速固定床热解反应器研究了玉米芯与聚乳酸的热解。结果表明，玉米芯与聚乳酸的共热解使热解油产率和热值增加，而水分含量降低。通过TGA/FTIR联用实时考察了玉米芯、聚乳酸及其二者混合条件下的热解气体析出特性，FTIR分析表明玉米芯与聚乳酸在共热解条件下存在明显的耦合作用。

Abstract

Pyrolytic process has a promising potential for the environmentally friendly upgrading of biomass and other materials such as plastics

coal.In this study

the influence of a biopolymer

polylactic acid (PLA) on the pyrolysis of corncob was investigated by using a fast pyrolysis fixed-bed reactor.The results indicated that the co-processing of PLA with corncob increased liquefaction yield and a lower water content as a function of the corncob/PLA ratio was obtained.Furthermore

the thermal degradation of corncob

PLA and their blends in nitrogen was studied at different temperatures by using TGA/FTIR.The gas evolved during degradation was identified by in situ FTIR.The results showed obvious synergies between corncob and PLA during co-pyrolysis.
