This paper reports a study about the effect of activity distributions of a bifunctional catalyst on the conversion and product distribution in a fixed-bed reactor. Uniform as well as increasing and decreasing activity profiles of both catalytic functions are considered. The analysis is performed assuming three different reaction schemes. Results show that reactor performance is greatly affected by the use of catalysts with non-uniform activity distributions.
