Abstract This study aims to produce high quality bio-oil by microwave co-pyrolysis of torrefied biomass (rice straw) and low density polyethylene (LDPE) using ZSM-5 as a catalyst. A central composite experimental design was used to optimize the reaction condition by response surface methodology analysis. The effects of reaction temperatures and catalyst dosages on the product yield and chemical selectivity of bio-oil were investigated. Results suggested that bio-oil obtained from torrefied biomass contained a lower water content compared with the control.The major chemical compounds of bio-oil were hydrocarbons, ketones, phenols, esters and alcohols (∼80%).Bio-oils with high hydrocarbon content (∼40% in the bio-oil) were obtained in the development of this experiment. Quadratic models were used to predict the bio-oil yield and chemical selectivity of the bio-oil obtained during the reactions.

使用 ZSM-5 作为高质量生物油催化剂的微波辅助热解生物质与废塑料

摘要 本研究旨在以ZSM-5为催化剂，通过微波共热裂解生物质（稻草）和低密度聚乙烯（LDPE）生产优质生物油。中心复合实验设计用于通过响应面方法分析优化反应条件。研究了反应温度和催化剂用量对生物油产品收率和化学选择性的影响。结果表明，与对照相比，从生物质中提取的生物油含水量较低。生物油的主要化学成分为烃类、酮类、酚类、酯类和醇类（~80%）。高烃类生物油在该实验的开发中获得了含量（在生物油中约 40%）。
