Due to looming demand for fossil fuels and environmental concerns over global warming, extensive attention has been given on the development of renewable energy. Biomass materials are used since millennia for meeting myriad human needs including energy and chemicals. In this study, co-pyrolysis characteristics of woody and grass type agricultural wastes, namely Borassus flabellifer and Cymbopogon flexuosus were studied in a fixed bed reactor to evaluate their potential use as source of bio-oil. The effects of operating parameters such as temperature, particle size and heating rate were investigated. In this co-pyrolysis process, the maximum yield of pyrolysis bio-oil 47.10 wt% can been obtained under the pyrolysis temperature of 500ºC, 1.0 mm particle size and at the heating rate of 30 ºC/min. The bio-oil product was analyzed for physical, elemental and chemical composition using Fourier transform infra-red (FTIR) spectroscopy and gas chromatography (GC).

木本和草类生物质的结合：废物管理，工艺参数的影响，热解生物油的产率及其色谱特性

由于对化石燃料的迫在眉睫的需求以及对全球变暖的环境关注，对可再生能源的开发给予了广泛关注。几千年以来，生物质材料一直用于满足人类的各种需求，包括能源和化学物质。在这项研究中，木质和草类农业废料，即黄牛（Borassus flabellifer）和弯柏（Cymbopogon flexuosus）的共热解特性在固定床反应器中进行了研究，以评估其作为生物油来源的潜在用途。研究了诸如温度，粒度和加热速率等操作参数的影响。在这种共热解过程中，在500ºC的热解温度，1.0 mm的粒径和30ºC/ min的加热速率下，可获得47.10 wt％的热解生物油最大产率。使用傅立叶变换红外（FTIR）光谱和气相色谱（GC）分析了生物油产品的物理，元素和化学组成。
