This article presents an analytical method for the calculation of the adiabatic time to maximum rate. The procedure is developed considering a thermal decomposition process described by a simple n-order kinetic and is based on the introduction of a special function that is possible by integrating analytically. The application of the method requires the knowledge of the thermokinetic parameters of the process under study and allows the calculation of the adiabatic time to maximum rate without the numerical integration of the heat and mass balance equations or the use of relationships based on particular simplifying hypotheses. Its validity has been demonstrated considering numerical and real experiments (thermal decomposition of trityl azide) providing in both cases times to maximum rate values which are very close to the real ones. © 2017 American Institute of Chemical Engineers AIChE J, 2017

使用分析方法对绝热时间进行最大速率评估

本文提出了一种计算绝热时间达到最大速率的分析方法。该程序的开发考虑了一个简单的n阶动力学所描述的热分解过程，并且是基于引入特殊功能的，该功能可以通过分析集成来实现。该方法的应用需要了解所研究过程的热动力学参数，并允许计算绝热时间至最大速率，而无需对热量和质量平衡方程进行数值积分或使用基于特定简化假设的关系式。考虑到数值和实际实验（三苯甲基叠氮化物的热分解），已经证明了其有效性，在两种情况下均提供了与真实实验非常接近的最大速率值。AIChE的Ĵ，2017年
