Abstract

We have reported the importance of biomass ratio in the co-pyrolysis of waste plastics to regulate the aromatic content and oxygenated compounds in hydrocarbon-rich fuels for enhancing engine performance. The study revealed that changing biomass to plastic ratio can control aromatic compositional change. The obtained product was characterized using different instrumentation techniques, such as NMR, FTIR, GCMS, etc., to identify the hydrocarbon types in the liquid product. Results revealed that it contains C₈-C₂₄ range carbon compounds with dominating aromatics compounds, as confirmed by ¹H NMR and FTIR analysis. The pyro-oils contain different hydrocarbons: olefins, paraffin, aromatics, esters, and alcohols. It was observed that the presence of biomass in co-pyrolysis produces oxygenated compounds up to ∼12.08 % and also enhances calorific value up to 55.4 MJ/kg from 48.3 MJ/kg due to the presence of longer hydrocarbon chains of esters in pyro-oil. Biomass co-pyrolysis also improved the fuel properties such as pour point (<-25°C) and 4°C increment in flash point. Engine performance showed that blending biomass pyro-oil obtained from B25PS75 reduced fuel consumption and increased BTE.

废塑料共热解中香蕉皮废生物质比例对调节芳烃含量和含氧化合物的影响：液体产品特征及其 CI 发动机性能研究

我们报告了废塑料共热解过程中生物质比例对调节富含碳氢化合物的燃料中芳烃含量和含氧化合物以提高发动机性能的重要性。研究表明，改变生物质与塑料的比例可以控制芳香成分的变化。利用核磁共振、傅立叶变换红外光谱、气相色谱等不同仪器对获得的产品进行表征，以确定液体产品中的碳氢化合物类型。结果表明，它含有 C8-C24 范围的碳化合物，其中以芳烃化合物为主，这一点已通过 1H NMR 和 FTIR 分析得到证实。焦油含有不同的碳氢化合物：烯烃、石蜡、芳烃、酯和醇。据观察，生物质在共热解过程中产生的含氧化合物高达 ∼12.08 %，由于热解油中存在较长的酯类碳氢链，热值也从 48.3 兆焦/千克提高到 55.4 兆焦/千克。生物质共热解还改善了燃料特性，如倾点（-25°C）和闪点提高 4°C。发动机性能表明，掺入从 B25PS75 中获得的生物质热油可降低油耗，提高 BTE。
