Catalyst poisoning — refers to the effect that a catalyst can be poisoned if it reacts with another compound that bonds chemically (similar to an inhibitor) but does not release, or chemically alters the catalyst. This effectively reduces the usefulness of the… … Wikipedia
selectivity — Many reactions can potentially occur in any real catalyst systems. Selectivity is the measure of the ability of the catalyst to promote desired reactions without affecting those that are not desired … Petroleum refining glossary
Catalyst for pressure swing adsorption — Pressure Swing Adsorption (PSA) processes rely on the fact that under pressure gases tend to be attracted to solid surfaces, or adsorbed. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or… … Wikipedia

Ziegler-Natta catalyst — A Ziegler Natta catalyst is a reagent or a mixture of reagents used in the production of polymers of 1 alkenes (α olefins). Ziegler Natta catalysts are typically based on titanium compounds and organometallic aluminium compounds, for example… … Wikipedia
CBS catalyst — Corey Bakshi Shibata catalyst The CBS catalyst or Corey Bakshi Shibata catalyst is an asymmetric catalyst derived from proline. It finds many uses in organic reactions such as the CBS reduction, Diels Alder reactions and [3+2] cycloadditions.… … Wikipedia
