What Are Some Real-World Uses of Catalysts in Industry?
Catalysts are very important in different industries because they help speed up chemical reactions without changing themselves. They do this by lowering the energy needed for a reaction to happen. Here are some key ways catalysts are used in the real world:
One of the most common uses of catalysts is in catalytic converters, which are found in most new cars. These devices use catalysts, like platinum, palladium, and rhodium, to change harmful gases into safer ones.
The Haber process is a key method for making ammonia (NH₃), which is very important for fertilizers.
Catalyst Used: Iron is usually the catalyst for this process.
Conditions: The reaction happens at high temperatures (around 450-500 °C) and under high pressure (150-250 atm).
Production: Thanks to the iron catalyst, about 150 million tons of ammonia are produced each year worldwide. This helps feed the world’s population.
The Contact Process is used to make sulfuric acid (H₂SO₄), one of the most produced chemicals in the world.
Catalyst Used: Vanadium(V) oxide is the catalyst here.
Chemical Reaction: The main reaction can be shown as:
Production Efficiency: The catalyst makes the production faster and allows it to happen at about 450 °C and 2 atm of pressure. This results in over 200 million tons of sulfuric acid being made each year.
In the food industry, catalysts are used to hydrogenate unsaturated fats, which makes them more stable and gives them a longer shelf life.
Catalyst Used: Nickel is the main catalyst used in this process.
How It Works: Unsaturated vegetable oils react with hydrogen to become more saturated.
Economic Impact: Hydrogenated oils are widely used in making margarine and shortening, contributing significantly to the UK food market, adding over £1 billion to the value of edible fats and oils.
Catalysts are also important in treating wastewater to remove harmful pollutants.
Catalysts Used: Titanium dioxide is often used in processes that require light.
How It Works: When exposed to UV light, titanium dioxide creates radicals that can break down various organic pollutants. This method can reduce pollution levels by over 90%, leading to cleaner water.
Catalysts are vital in many industries. They help speed up reactions, use less energy, and lessen the environmental impact. Their use makes processes more efficient and contributes to a more sustainable industry. Learning about catalysts shows us how important they are in chemical reactions and modern factories.
