BAND BROADENING IN SOLID PHASE REACTORS PACKED WITH CATALYST FOR REACTIONS IN CONTINUOUS-FLOW SYSTEMS.

Article abstract of DOI:10.1021/ac00260a006

The band broadening in a catalytic bed reactor, in which pulses of reactant are introduced into a stream of liquid flowing through the bed of solid catalyst, is discussed. The chemical reaction concerned and the separation of the product(s) from the pulse of reactant cause band broadening, which is dependent on the reaction rate and on the difference in the retention of product(s) and reactant. A quantitative relationship has been derived for the case of first-order klnetics. The decomposition of diacetone alcohol on alumina and the catalytic hydrolysis of 1-naphthyl N-methylcarbamate on a basic ion exchanger have been studied as model systems; the results are in agreement with the mathematical models.
