合成气制重质烃的方法之一是费托合成法。该工艺存在热点形成、转化率低等瓶颈问题。本文采用计算流体力学技术对合成气的转化和产物分布进行了模拟。此外，热点形成的催化固定床反应器中进行了研究，在几个运行。模拟结果表明，由于反应速率较高，反应器的前、中段更容易形成热点。根据模拟结果，热点的温度随着入口温度以及压力的增加而增加。在进行的许多CFD运行中，发现费托合成的最佳温度和压力分别为565 K和20 bar。由于反应器似乎在最佳条件下工作得很好，反应速率和催化剂持续时间将同时达到最大。
Abstract One of the interesting methods for conversion of synthesis gas to heavy hydrocarbons is Fischer–Tropsch process. The process has some bottlenecks, such as hot spot formation and low degree of conversion. In this work, computational fluid dynamics technique was used to simulate conversion of synthetic gas and product distribution. Also, hot spot formation in the catalytic fixed-bed reactor was investigated in several runs. Simulation results indicated that hot spot formation occurred more likely in the early and middle part of reactor due to high reaction rates. Based on the simulation results, the temperature of hot spots increased with increase in the inlet temperature as well as pressure. Among the many CFD runs conducted, it is found that the optimal temperature and pressure for Fischer–Tropsch synthesis are 565 K and 20 bar, respectively. As it seems that the reactor shall work very well under optimal conditions, the reaction rates and catalyst duration would simultaneously be maximum .
