Katalyysisovelluksissa refers to the practical applications of catalysis. Catalysis is a process that increases the rate of a chemical reaction without the catalyst itself undergoing any permanent chemical change. These applications are fundamental to many industrial processes, significantly impacting economics and environmental sustainability.

In the chemical industry, catalysis is widely used for the synthesis of a vast array of products. For instance, the Haber-Bosch process, a cornerstone of ammonia production, relies on iron-based catalysts to enable the reaction between nitrogen and hydrogen. This ammonia is then used to produce fertilizers, essential for global food security. Similarly, catalytic converters in automobiles utilize platinum, palladium, and rhodium to convert harmful pollutants like carbon monoxide, nitrogen oxides, and unburnt hydrocarbons into less toxic substances such as carbon dioxide, nitrogen, and water.

Petroleum refining is another major area where catalysis plays a crucial role. Processes like fluid catalytic cracking (FCC) use zeolites as catalysts to break down large hydrocarbon molecules in crude oil into smaller, more valuable ones, such as gasoline. Hydrogenation and dehydrogenation reactions, also catalyzed, are vital for producing various petrochemicals and polymers.

Beyond these large-scale industrial uses, catalysis finds application in environmental remediation, such as in the purification of wastewater and the removal of air pollutants. Research continues to explore new catalytic materials and processes to enhance efficiency, selectivity, and sustainability across numerous fields, from energy production and storage to the development of new pharmaceuticals. The understanding and application of catalysis remain central to advancing chemical science and technology.
