The most common use of most molecular sieves is to remove water from a chemical mixture. This process is called desiccation. Sieves are made from solid materials that have many tiny pores within them. These porous materials take in the small water molecules but keep out the larger molecules of the other substances.
Catalysts are materials or substances used to provoke a reaction between two or more other substances. In many cases, the catalyst that is used is made from a solid precious metal that has been placed in the mixture with the other chemicals. Many common consumer products that are used every day could not exist without the use of a catalyst.
A research catalyst is one of the most important elements of any scientific or research driven chemical process. If you don't know the differences between each available catalyst you can take advantage of, you may not be able to run your reactions and chemical engineering processes correctly. This means you wont' get the results you want or need. Get the best catalysts for your research.
Reactor design is the process through which chemical reactions are designed and developed to be used by researchers, developers, and product creators to meet scientific goals and product development quotas. Different chemical reactions lead to different outcomes, and you need to know how to accurately design the chemical reactions you need.
Catalysis is the process through which a reaction is initiated, sped, or slowed through the introduction of a catalytic substance to the chemical mix. Some reactions simply wouldn't be abel to take place without the aid of a catalyst, while other reactions would progress far too slowly to be valuable without this key ingredient.
