1. Proper Reactor Design: Ensuring that the reactor is designed to provide uniform flow and mixing can help in the correct placement of the catalyst. 2. Uniform Catalyst Distribution: In systems where the catalyst is in a fixed bed or slurry form, ensuring a uniform distribution can prevent hotspots and concentration gradients. 3. Adequate Mixing: In homogeneous catalysis, thorough mixing can help in the even distribution of the catalyst and reactants, minimizing the chances of incorrect placement. 4. Use of Supports: In heterogeneous catalysis, using suitable supports can help in the proper dispersion of the catalyst, enhancing its effectiveness.
