THE MODELING OF COBALT CATALYST DEACTIVATION IN THE FISHER - TROPSCH SYNTHESIS PROCESS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
Cobalt catalyst is one of the most important catalysts that used in the Fisher - Tropsch process . This paper is discussing the deactivating factors of cobalt catalyst . The most important factors can be noted to 4 factors of sintering , coke , poisoning and water. In this study, modeling was conducted in a fixed bed reactor and the corresponding equations were solved using Matlab software . The effect of the temperature and other factors such as the ratio of hydrogen to carbon monoxide was studied on the efficiency and percentage of conversion of components . Data regarding drop of the catalyst activity with time was fit ted by a power model and then with respect to the achieved power was discussed about the mechanism of catalyst deactivation . According to the results , the water can be considered one of the most important factors of deactivation of the catalyst
