1.General Information
• Environmental waste problems: Organic and inorganic pollutants from industrial, agricultural and domestic sources threaten the environment.
• Importance of catalyst systems: Catalysts accelerate chemical reactions and convert harmful substances into less harmful or useful compounds.
⚗️ 2. What are Catalyst Purification Systems?
Definition: Substances that accelerate chemical reactions and generally do not change at the end of the reaction.
Types of catalysts:
🔹 Homogeneous catalysts: In the same phase as the reactants (usually liquid)
🔹 Heterogeneous catalysts: In a different phase than the reactants (usually solid)
🔹 Biocatalysts: Biological substances such as enzymes catalysts
💧 3. Catalytic Treatment Processes
🔥 a. Gas Waste Treatment
Application: Reduction of NOx, CO and hydrocarbons in automotive exhaust systems
Catalysts used:
🟡 Platinum (Pt), Palladium (Pd), Rhodium (Rh)
🌊 b. Wastewater Treatment
Application: Removal of toxic compounds such as organic dyes and phenols
Advanced oxidation processes (AOPs):
🔹 Photocatalysis (such as TiO₂)
🔹 Ozone + catalyst combinations
Catalyst example: TiO₂, ZnO, Fe₂O₃
🌱 c. Soil Pollution Removal
Application: Pesticides, heavy metals, petroleum derivatives
Used: Biocatalysts and nanocatalysts
🛠️ 4. Catalyst Usage Areas
