热化学储热是一种很有前景的提高热能效率的技术。为了研究 CaO/Ca(OH)2 反应的耐久性并开发一种再活化方法，对具有厚填充床的填充床反应器进行了重复充电/放电操作，并研究了放电行为、最终转化率和反应物活性的变化。由于形成了失活的烧结反应物块，第53次放电操作使放电时间减半并且最终转化率降低。为了提高耐用性，在第 54 次放电操作期间实施了使用高压蒸汽的再活化方法。与重新激活前的放电操作相比，重新激活后，最终转化率提高了15%，放电时间增加了两倍，证实了这种简单的重新激活方法的成功。
Thermochemical heat storage is a promising technology for improving thermal energy efficiency. To investigate the durability of the CaO/Ca(OH)2 reaction and develop a reactivation method, repetitive charging/discharging operation of a packed bed reactor with a thick packed bed was conducted, and variations in the discharging behavior, final conversion, and reactant activity were investigated. Owing to the formation of a deactivated sintered reactant block, the discharging time halved and the final conversion ratio decreased by the 53rd discharging operation. To enhance durability, a reactivation method using high-pressure vapor was implemented during the 54th discharging operation. Following reactivation, the final conversion increased 15%, and the discharging time tripled when compared with the discharging operation before reactivation, confirming the success of this simple reactivation method.
