What is Catalysis?
Catalysis refers to the acceleration of a chemical reaction by a substance known as a
catalyst, which itself remains unchanged at the end of the reaction. Catalysts are crucial in numerous industrial processes, enabling efficient and economical production of a wide range of products.
Why is Catalysis Important in Industry?
The importance of catalysis in industrial manufacturing cannot be overstated. It allows for higher reaction rates, lower energy consumption, and increased selectivity, which results in fewer by-products and waste. This leads to more sustainable and environmentally friendly processes. Catalysis is central to the production of essential chemicals, energy, and materials.
Homogeneous catalysts: These catalysts are in the same phase as the reactants, usually in a liquid state. They are often used in processes like the hydroformylation of alkenes.
Heterogeneous catalysts: These catalysts exist in a different phase than the reactants, typically as solids. They are widely used in processes such as the catalytic cracking of petroleum and the Haber-Bosch process for ammonia synthesis.
BASF: Known for a wide range of catalysts used in chemical synthesis, pollution control, and energy applications.
Johnson Matthey: Specializes in catalysts for automotive emission control, hydrogen production, and fuel cells.
Clariant: Offers catalysts for petrochemical refining, chemical production, and environmental applications.
Evonik Industries: Focuses on catalysts for fine chemicals, pharmaceutical production, and industrial gases.
Albemarle Corporation: Provides catalysts for polyolefin production, refining, and specialty chemicals.
