Abstract

A simple diagnostic test, the titration of palladium and platinum catalysts with carbon disulfide, has been developed to detect mass transfer problems. This method works for liquid-phase hydrogen-ations and is based on the linear poisoning of addition by carbon disulfide. The titration curve is linear, unless mass transfer problems occur. This new test can furnish the same information as the Madon-Boudart test, but does not require the preparation of two catalysts with different loadings. Not only is it useful for detecting any kind of diffusion limitation, but also it is able to determine the maximum rate, free from any mass transport resistances.
