Biochar is carbon-rich product generated from biomass through pyrolysis. In this study, the effects of pyrolysis temperature and heating rate on the yield and physicochemical and morphological properties of biochars obtained from safflower seed press cake were investigated. The results showed that the biochar yield and quality depend principally on the applied temperature where pyrolysis at 600 °C leaves a biochar with higher fixed carbon content (80.70%) and percentage carbon (73.75%), and higher heating value (30.27 MJ kg(-1)) in comparison with the original feedstock (SPC) and low volatile matter content (9.80%). The biochars had low surface areas (1.89-4.23 m(2)/g) and contained predominantly aromatic compounds. The biochar could be used for the production of activated carbon, in fuel applications, and water purification processes.
生物炭是一种通过热解从生物质中产生的富碳产物。本研究考察了热解温度和升温速率对红花籽压榨饼制备的生物炭产率及理化和形态特性的影响。结果表明，生物炭产率和质量主要取决于所施加的温度，与原始原料（SPC）和低挥发物含量（9.80%）相比，在 600°C 下热解得到的生物炭具有更高的固定碳含量（80.70%）和碳百分比（73.75%），以及更高的热值（30.27 MJ kg(-1))。生物炭的比表面积较低（1.89-4.23 m(2)/g），主要含有芳香族化合物。生物炭可用于活性炭的生产、燃料应用和水净化过程。
