Study Notes
Background on Catalysis
- Catalysts are essential for chemical transformations in the industry.
- Approximately 85-90% of chemical products rely on catalytic processes.
- Catalysts enable industrial processes to operate under feasible pressure conditions.
Definition of a Catalyst
- A catalyst accelerates a chemical reaction without changing its structure post-reaction.
Importance of Catalysts
- Provide a reaction pathway with lower activation energy.
- Increase reaction rates.
- Allow reactions to proceed under conditions where high temperatures and pressures may be impractical.
- Overcome thermodynamic limitations on product formation.
Classification of Catalysts
-
By State:
- Gas, Liquid, Solid
-
By Nature:
- Inorganic: Includes gases, metals, metal oxides, inorganic acids, and bases.
- Organic: Comprises organic acids and enzymes.
-
By Phase System:
- Homogeneous: Soluble catalysts in a single phase, often liquid.
- Heterogeneous: Different phases involved in the reaction.
Types of Catalytic Action
- Acid-base catalysis.
- Enzymatic/biocatalysis.
- Photocalysis.
- Electrocatalysis.
Applications of Catalysis
- Catalytic converters are significant in environmental applications to reduce emissions.
Homogeneous Catalysis in the Chemical/Petrochemical Industry
-
Carbonylation Reactions:
- Involves reactants like Methanol and CO producing Methyl acetate, among others.
-
Common Products and Metals:
- Acetic acid, Acetic anhydride, and Methyl methacrylate often use Rhodium (Rh) or Cobalt (Co) as catalysts.
-
Production of Polymers:
- Various metals such as Palladium (Pd), Rh, and Nickel (Ni) are employed in producing ethylene and propylene.
