Source sentences:
text: During the reaction between the chemical intermediates and the reactants, the catalyst is regenerated.
text: In a catalyzed reaction, the catalyst generally enters into chemical combination with the reactants but is ultimately regenerated, so the amount of catalyst remains unchanged.
text: Since the cracking reactions produce some carbonaceous material (referred to as catalyst coke) that deposits on the catalyst and very quickly reduces the catalyst reactivity, the catalyst is regenerated by burning off the deposited coke with air blown into the regenerator.
text: Since catalysts are regenerated, catalytic cycles are usually written as a sequence of chemical reactions in the form of a loop.
text: Normally, the catalyst can be regenerated perhaps 3 or 4 times before it must be returned to the manufacturer for reclamation of the valuable platinum and/or rhenium content.
text: Catalysts generally change in the course of a reaction but are regenerated.
