This study was an investigation of the role of important parameters influencing pyrolysis yields from soybean cake. Experiments were carried out at temperatures ranging from 400 to 700 degrees C, for various nitrogen flow rates, heating rates and particle sizes. The maximum liquid yield was 42.83% at a pyrolysis temperature of 550 degrees C with a sweeping gas rate of 200 cm3 min(-1) and heating rate of 700 degrees C min(-1) for a soybean cake sample having 0.425 < D(p) < 0.85 mm particle size. The various characteristics of liquid product were identified. Thus, the aliphatic sub-fraction of the bio-oil was analysed by GC-MS and further structural analyses of bio-oil and aromatic and polar sub-fractions were conducted using FT-IR and 1H-NMR. The H/C ratios and the structural analysis of the fractions obtained from the biocrudes showed that the fractions were quite similar to currently utilised transport fuels.
本研究旨在探究影响大豆饼热解产率的重要参数的作用。实验在400至700摄氏度的温度范围内进行，涉及不同的氮气流量、加热速率和颗粒尺寸。对于粒径为0.425 < D(p) < 0.85毫米的大豆饼样品，在热解温度为550摄氏度、吹扫气体速率为200立方厘米每分钟（-1）且加热速率为700摄氏度每分钟（-1）的条件下，最大液体产率为42.83%。确定了液体产物的各种特性。因此，通过气相色谱 - 质谱联用仪（GC-MS）分析了生物油的脂肪族亚组分，并使用傅里叶变换红外光谱仪（FT-IR）和核磁共振氢谱（1H-NMR）对生物油以及芳香族和极性亚组分进行了进一步的结构分析。从生物原油中获得的馏分的氢碳比（H/C）和结构分析表明，这些馏分与目前使用的运输燃料非常相似。
