摘要

该文基于Aspen Plus构建由10个反应釜组成的聚丙烯和生物质共气化反应动力学模型

数值分析聚丙烯和生物质在氧气和水蒸气中的产气特性。结果表明：聚丙烯增加提高了CO和CH4的体积分数

水蒸气增加提高了H2的体积分数。H2+CO合成气体积分数在聚丙烯质量分数为9%~23%范围内有最高值。随着S/C（水蒸气与生物质中碳的质量比）的增加

H2+CO合成气体积分数在600~700 ℃时升高

在800~1000 ℃时略有下降。在9%~23%聚丙烯质量分数下

H2/CO在700~1000 ℃下有最大值。聚丙烯增加会降低CO2体积分数

当S/C为0.2、气化温度为1000 ℃时CO2体积分数有最大值。

Abstract

An effective solution for utilizing solid waste is the production of syngas through the co-gasification of polypropylene and biomass. In the present study

a kinetic model for the co-gasification of polypropylene and biomass was developed using ten reactiors kettles from Aspen Plus software. The gas production performance of both polypropylene and biomass was simulated numerically under oxygen and steam atmospheres. The results indicated that an increase in polypropylene improved the volume fractions of both CO and CH

while an increase in steam enhanced the volume fraction of H. The volume fraction of syngas （H+CO） increased with rising gas temperature

initially increased and then decreased with the mass fraction of polypropylene

reaching a maximum value within the range of 9% to 23%. Furthermore

as the steam-to-carbon （S/C） ratio increased

the volume fraction of syngas （H+CO） increased at temperatures of 600 ℃ to 700 ℃

but decreased slightly at temperatures of 800 ℃ to 1000 ℃. At mass fractions of polypropylene between 9% and 23%

the maximum H/CO ratio occurred at temperatures between 700 ℃ to 1000 ℃. The H/CO ratio increased with rising S/C

and its rate of increase declined with rising temperature. A reduction in the CO volume fraction was observed with increasing polypropylene

while it reached a maximum value at a temperature of 1000 ℃ and an S/C ratio of 0.2.
