  • 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
