How Is Pressure Control Achieved in Heterogeneous Catalysis?
In heterogeneous catalysis, where the catalyst is in a different phase than the reactants, pressure control is often achieved using closed reactors like autoclaves. High pressure helps to increase the contact between gaseous reactants and the solid catalyst surface, thus enhancing the reaction rate. For example, in catalytic hydrogenation, high pressure facilitates the adsorption of hydrogen onto the catalyst surface.
