The regeneration process for coked iron-oxide cinder, which has been proposed as an Effective contact (heat carrier) for thermal pyrolysis of light hydrocarbon feedstock, was studied. Oxidative regeneration of cinder at various temperatures was researched. The regeneration of the coked contact (determination of the dependence of the degree of coke burnout on time) was described mathematically. The reactivity of the coked cinder during oxidation by atmospheric oxygen was compared to those of other catalysts. Dynamic mass changes of the coked cinder were also investigated using dynamic thermogravimeny on a derivatograph. The main features of the contact mass changes as functions of time, temperature, and temperature rise rate during its oxidation by atmospheric oxygen were found. Research on multiple pyrolysis/regeneration cycles proved that the iron-oxide cinder could be used cyclically as a heat carrier for thermal contact pyrolysis. The yields of the target products remained constant.

卷曲氧化铁渣再生工艺

研究了焦化氧化铁煤渣的再生过程，该煤渣已被提议作为轻烃原料热裂解的有效接触（热载体）。研究了煤渣在不同温度下的氧化再生。焦炭接触的再生（确定焦炭烧尽程度与时间的关系）以数学方式描述。将焦化煤渣在大气氧氧化过程中的反应性与其他催化剂的反应性进行了比较。焦化煤渣的动态质量变化也在衍生图上使用动态热重分析进行了研究。发现了接触质量在其被大气氧氧化过程中作为时间、温度和升温速率的函数而变化的主要特征。对多次热解/再生循环的研究证明，氧化铁渣可以循环用作热接触热解的热载体。目标产品的产量保持不变。
