Catalyst poisoning is the partial or total deactivation of a catalyst by a chemical compound.

Jun 8, 2023 · Alloying Pt with Fe played a crucial role in accelerating oxidation/reduction reactions and overcoming CO poisoning. These findings highlight the potential for improving passive …

Jul 1, 2012 · In this paper we exemplified results from poisoning tests applied to Passive Autocatalytic Recombiners samples in typical severe accident conditions of light water reactor …

[4] The oxidation of hydrocarbons by air or oxygen is the basis of autoxidation. Like many radical reactions, the rate vs time plot shows a sigmoidal behavior, characteristic of autocatalysis. [5] …

catalyst poison, substance that reduces the effectiveness of a catalyst in a chemical reaction. In theory, because catalysts are not consumed in chemical reactions, they can be used …

The poisoning of catalysts is essentially a preferential adsorption effect dependent on the formation of abnormally strong adsorptive bonds between a catalyst and certain types of …

Catalyst poisoning, which is either reversible or irreversible, is characterized by strong adsorption of a reactant, an intermediate or a product in the active sites of the catalyst, thereby preventing …

Jun 8, 2011 · We detail the different categories of autocatalyses and compare them on the basis of their mechanistic, kinetic, and dynamic properties. It is shown how autocatalytic patterns …

poisoning modulus for these four configurations. Where there is free access to the interior surface no configurational dependence exists, but as hL increases large differences become apparent …

The data suggest that catalytic recombiner has sufficient capability in the BWR specific (inert) condition, and under presence of poisoning material postulated in hypothetical accident condition.
