摘要:         以真实三叶草型加氢裂化催化剂三维体相环境为计算实体,以模拟工业运行温度的函数作为边界条件,采用无网格数值方法求解傅立叶传热方程,并通过计算结果分析加氢裂化催化反应过程中外界温度波动对催化剂内部温度分布的影响。结果表明,实际反应过程中催化剂内部并非等温反应,在加氢裂化反应过程中外界的反应温度波动以及催化剂内部的热点分布对催化剂团簇内部的温度场分布有一定的影响。催化剂体相内部的平均温度也随着反应体系放热情况、催化剂粒径、原料油密度、反应空速以及催化剂内部热点分布情况的不同而有所变化。

Abstract:

      Based on three-dimensional somatic environment of the real clover type hydrocracking catalyst as the computational entity and the simulated industrial operating temperature as the boundary condition. The Fourier heat transfer equation is solved by the meshless numerical method. Then the influence of external temperature fluctuation on the internal temperature distribution of the catalyst was analyzed by using the calculated results. The analysis results show that the actual reactions in the catalyst is not isothermal reaction. At the same time, the fluctuation of the reaction temperature and the hot spot inside the catalyst have a certain influence on the temperature distribution for the catalyst cluster in the hydrocracking process. Catalyst bulk phase inner average temperature is influenced by heat of reaction, the catalyst particle size, material density, reaction space velocity and catalyst inner hotspot distribution.
