为了更好地理解这一过程的机理，在填充床中研究了棕榈油废弃物在不同温度下的热解过程，重点考察了固体残渣的化学结构和物理性质以及气体释放特性的变化。首先，将三种棕榈油废弃物从室温升温至1000 °C进行热解，热解产物主要为固体炭、液体油和富氢气体。气体组分主要由H2、CO2、CO和CH 4以及微量C2 H4和C2 H6组成。CO和CO2在较低温度（<450 °C）下释放，而H2在较高温度（600−700 °C）下释放。其次，分析了生物质壳在不同温度（300，400，...，1000 °C）。利用各种方法（包括micro-GC、FTIR、GC-MS、ASAP 2010、SEM和CNHS/O分析仪）对热解产物进行了彻底鉴定，以了解温度对产物性质的影响，从而了解所涉及的反应机理。开始...
To better understand the process mechanism, pyrolysis of palm oil wastes was investigated at different temperatures in a packed bed, with focus on the changing of chemical structure and physical characteristics of solid residues and gas-releasing properties. First, three palm oil wastes were pyrolyzed with temperature increasing from the ambient to 1000 °C, and the main products from it were solid charcoal, liquid oil, and hydrogen-rich gas. The gas component mainly consisted of H2, CO2, CO, and CH4 together with trace C2H4 and C2H6. CO and CO2 evolved out at lower temperature (<450 °C), while H2 released at higher temperature (600−700 °C). Second, the decomposition property of biomass shell was analyzed at variable temperatures (300, 400, ..., 1000 °C). The pyrolysis products were thoroughly identified using various approaches (including micro-GC, FTIR, GC-MS, ASAP2010, SEM, and CNHS/O analyzer) to understand the influence of temperature on product properties and, thus, reaction mechanism involved.
