Modeling of Iron Catalyst Deactivation and the Impact of Different Promoters on this Model

摘要

The synthesis of Fischer Tropsch is a catalytic process converting synthesis gas to liquid fuels. Iron catalytic activity changed due to the increase in metals as a promoter. The catalyst was determined at a temperature of 280 ° and the ratio of H2/CO = 2/1, and the metals were added to the catalyst including Mn, Cr, Mo, Ta, V and Zr. The rate of the catalyst deactivation was investigated and specified. The catalyst deactivation model followed the first order GPLE model and the catalyst FeZr is deactivated earlier than other catalysts.
