Backwashing is a process used in various industries, particularly in catalysis, to clean and regenerate a packed bed of catalyst particles. During catalytic reactions, the catalyst bed can become fouled with impurities, by-products, or unreacted feed components, which reduce the efficiency and effectiveness of the catalytic process. Backwashing involves reversing the flow of the fluid (usually a liquid or gas) through the catalyst bed to dislodge and remove these accumulated contaminants.
