Catalyst regeneration is a multistep procedure. Charlotte-based SCR-Tech (a subsidiary of Catalytica Energy Systems), for example, uses a patented ultrasonic process to remove physical and microscopic ... In general, chemical reactions occur faster in the presence of a catalyst because the catalyst provides an alternative reaction mechanism (reaction pathway) having a lower activation energy than the noncatalyzed mechanism.

Understanding the Context

This particular software suite updates the AMD Catalyst™ Display Driver and the AMD Catalyst™ Control Center. This unified driver has been updated, and is designed to provide enhanced performance and reliability. Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.

Final Thoughts

In chemistry and biology, a catalyst is a substance the increases the rate of a chemical reaction without being consumed by it. Catalysis is the process of speeding up a reaction using a catalyst. The word “catalyst” comes from the Greek word kataluein, which means to loosen or untie. A catalyst is a substance that speeds up a chemical reaction without itself undergoing any permanent chemical change. In other words, it’s not consumed in the reaction—it merely facilitates it.
