catalysis

 [kah-tal´ĭ-sis]
increase in the velocity of a chemical reaction or process produced by the presence of a substance that is not consumed in the net chemical reaction or process; negative catalysis denotes the slowing down or inhibition of a reaction or process by the presence of such a substance. adj., adj catalyt´ic.

ca·tal·y·sis

(kă-tal'i-sis),
The effect that a catalyst exerts on a chemical reaction.

catalyst, which takes no part in the reaction and remains unchanged.

covalent catalysis
one type of enzyme reaction with substrates to form very unstable, covalently joined enzyme-substrate complexes which undergo further reaction.

Eight of the twenty-four units supplied to KAUST incorporate the most recent contributions of PID Eng & Tech into the rapid development of the Science of Catalysis, and consists of a phase separator at the product output of the high-pressure reactor which, with no dead volume allows the real-time separation of two immiscible liquid phases (water and hydrocarbons, standard products in the conversion reactions of gaseous hydrocarbons into liquid hydrocarbons using F-T) and non-condensing gases.
By endowing the chair, SABIC seeks to create a world-class center of ex- cellence in polymer catalysis based on a synergistic collaboration between the newly endowed KAUST chair and SABIC's own well-established exper- tise in catalyst development, a state- ment said.
