The present work is an attempt to develop a mathematical model which describes the production of aromatics and hydrogen in the naphtha platforming unit of the refinery of Skikda in Algeria. The process is carried out in a cascade of four cylindrical different sized reactors. The mathematical model is based on the assumption that the system is a non-isothermal heterogeneous four fixed bed reactors with a catalytic pellet that contains two metallic catalysts and an acidic catalyst. These catalysts are assumed to be distributed, throughout the pellet, in a non uniform way. The metallic catalysts are Platinum (Pt) and Rhenium (Re). Furthermore, an axial dispersion and resistances to mass and thermal transfers have been considered in this model. The results from the simulation of the model were compared to industrial results, at the start of the cycle well before any deactivation process has taken place, obtained from the naphtha platforming unit of the refinery of Skikda in Algeria. This comparison was carried out in order to validate the model. This led to good agreement between the simulation results and the industrial results. Under the same conditions of validation but with a change in catalyst distributions, the simulated results show an enhancement in the production of aromatics, hydrogen and light products. The simulated results also showed that the fourth reactor is not necessary.

目前的工作是尝试建立一个数学模型，该模型描述阿尔及利亚斯基克达精炼厂的石脑油平台化装置中芳烃和氢气的产生。该方法在四个圆柱形不同尺寸的反应器的级联中进行。该数学模型基于以下假设：该系统是非等温多相四个固定床反应器，带有包含两种金属催化剂和酸性催化剂的催化颗粒。假定这些催化剂以不均匀的方式分布在整个颗粒中。金属催化剂是铂（Pt）和R（Re）。此外，在该模型中考虑了轴向扩散以及对传质和传热的阻力。将模型仿真的结果与工业结果进行比较，在循环开始之前，很久没有任何停用过程发生，该过程可从阿尔及利亚斯基克达精炼厂的石脑油平台装置获得。进行此比较是为了验证模型。这导致了仿真结果与工业结果之间的良好一致性。在相同的验证条件下，但催化剂分布有所变化，模拟结果表明芳烃，氢气和轻质产品的生产有所提高。模拟结果还表明第四反应器不是必需的。在相同的验证条件下，但催化剂分布有所变化，模拟结果表明芳烃，氢气和轻质产品的生产有所提高。模拟结果还表明第四反应器不是必需的。在相同的验证条件下，但催化剂分布有所变化，模拟结果表明芳烃，氢气和轻质产品的生产有所提高。模拟结果还表明第四反应器不是必需的。
