مقایسه مدل‌سازی کوپل حرارتی فرآیند کاتالیستی تری ریفورمینگ متان و هیدروژن زدایی از متانول در بستر ثابت و بستر سیال

In this configuration, the thermal couplings of two processes in terms of catalytic bed have been studied. The catalytic bed contains a fix bed and a fluid bed. The processes under study in this project are the methane tri-reforming process in the calefactory section and the methanol dehydrogenation process in the endothermic section, which are carried out separately in the plug reactor. In this modeling, once a methane tri-reforming process in a fixed bed and once in a fluid bed with a methanol dehydrogenation process in a fixed bed in improved coupling method are coupled, and their results have been studied and compared. The results of this modeling indicate the feasibility of coupling of the two processes. In this project, a homogeneous, one-dimensional and stable model is proposed to predict the behavior of these reactors. The rates of methane conversion in the fixed bed and in the fluid bed in the calefactory section were obtained as 92.9% and 90%, respectively; and the yields of hydrogen in the fixed bed and fluid bed were obtained as 1.8 and 1.75, respectively; and the H₂/CO ratio in the fixed bed and fluid bed ware obtained as 1.94 and 2.02, respectively. Generally, according to the results, the yield of the fixed bed coupling for this configuration is more favorable in methane conversion and yields of hydrogen than that of the fluid bed coupling.
