农业剩余物形式的生物质在新的可再生能源中越来越受欢迎，特别是考虑到其广泛的潜力和丰富的用途。热解是生物质热转化过程中最重要的过程。在这项研究中，生物油的各种特性获得在不同的热解条件下从红花籽压榨饼（SPC）进行了鉴定。对生物油进行了元素分析和热值测定，并利用色谱、1H NMR、FTIR和GC等光谱技术对生物油的化学组成进行了研究。测定了生物油的运动粘度、闪点、密度、含水量和ASTM蒸馏等燃料性质。生物油的化学组成表明，存在一定量的烃，而氧化和极性馏分占主导地位。从红花籽压榨饼中提取的生物油是一种环境友好的生物燃料和化学品原料。
Biomass in the form of agricultural residues is becoming popular among new renewable energy sources, especially given its wide potential and abundant usage. Pyrolysis is the most important process among the thermal conversion processes of biomass. In this study, the various characteristics of bio-oils acquired under different pyrolysis conditions from safflower seed press cake (SPC) were identified. The elemental analyses and calorific values of the bio-oils were determined, and then the chemical compositions of the bio-oils were investigated using chromatographic and spectroscopic techniques such as column chromatography,1H NMR, FTIR and GC. The fuel properties of the bio-oil such as kinematic viscosity, flash point, density, water content and ASTM distillation were also determined. Chemical compositions of bio-oils showed that some quantities of hydrocarbons were present, while oxygenated and polar fractions dominated. The bio-oils obtained from safflower seed press cake were presented as an environmentally friendly feedstock candidate for biofuels and chemicals.
