WebJul 16, 2024 · A heterogeneous catalytic reaction has at least four steps in its reaction mechanism: Adsorption of the reactant (s) onto the surface of the catalyst. Diffusion of the product (s) from the surface into the gas or liquid phase (desorption) Any one of these steps may be slow and thus may serve as the rate determining step. WebThe catalyst used in the reactor is a crucial design consideration that greatly affects the final products. If sulfur removal is the primary goal, cobalt-molybdenum catalysts are favored. If the crude oil is relatively low in sulfur, nitrogen removal becomes the priority and nickel-molybdenum catalysts are chosen.
