Abstract Camellia oleifera shell (CAS) was stored under three temperature and relative humidity conditions (15 °C-50%, 35 °C-50% and 35 °C-80%) for 32 days, and subsequently compressed into pellets to investigate the influence of storage on pelletization and pellet properties. The characteristics of stored CAS, energy consumption during pelletization, and pellets' properties (density, Meyer hardness, pyrolysis kinetics and combustion behaviour) were analyzed. After storage, the hemicellulose content of the CAS was decreased slightly, and thus increased water resistance. The stored CAS was more easily pyrolyzed, and exhibited higher stability towards combustion. In addition, lower and more-stable energy was required for the stored CAS to produce pellets with higher single pellet density and strength, compared with that required for the control CAS. Therefore, the storage process is conducive for improved pelletization and pellets' properties in industrial applications.

油茶 Abel 的造粒。储存后的外壳：能耗和颗粒特性

摘要 油茶壳（CAS）在三种温度和相对湿度条件（15 °C-50%、35 °C-50% 和 35 °C-80%）下储存 32 天，然后压制成颗粒以研究储存对造粒和造粒性能的影响。分析了储存 CAS 的特性、造粒过程中的能量消耗和球团的特性（密度、迈耶硬度、热解动力学和燃烧行为）。储存后，CAS 的半纤维素含量略有下降，从而增加了耐水性。储存的CAS更容易热解，对燃烧表现出更高的稳定性。此外，储存的 CAS 需要更低和更稳定的能量来生产具有更高单颗粒密度和强度的颗粒，与控制CAS所需的相比。因此，储存过程有利于在工业应用中改善造粒和颗粒的性能。
