What Are Some Catalytic Processes for Waste Treatment?
Several catalytic processes are utilized for the treatment of industrial waste:
1. Catalytic Cracking: This process is used in the petroleum industry to break down large hydrocarbon molecules into smaller, more useful ones, such as gasoline and diesel.
2. Selective Catalytic Reduction (SCR): This process reduces nitrogen oxides in exhaust gases by converting them into nitrogen and water using a catalyst, often employed in power plants and industrial boilers.
3. Photocatalysis: Utilizes light energy to activate a catalyst, such as titanium dioxide, to break down pollutants in wastewater and air.
4. Hydrodesulfurization: Removes sulfur compounds from fossil fuels, significantly reducing sulfur dioxide emissions when these fuels are burned.
