Abstract

The authors describe an attempt to use radioisotopes in the study of the kinetics of heterogeneous catalytic processes in a state of equilibrium. The investigation was carried out by the circulation method. After establishment of equilibrium, a small amount of S{sup 35}O{sub 2} was introduced into the system as a tracer and its conversion rate into S{sup 35}O{sub 3} was measured. From that rate the speed of the direct and inverse processes of oxidation of SO{sub 2} on the catalyst was calculated. Possible sequence patterns for the process are suggested and discussed.

La investigacion se llevo a cabo por el metodo de circulacion. Una vez establecido el equilibrio, se introdujo en el sistema una pequena cantidad de {sup 35}SO{sub 2} como trazador y se midio su indice de conversion en {sup 35}SO{sub 3}. De dicho indice se dedujo la velocidad de los procesos directo e inverso de oxidacion del SO{sub 2} en presencia del catalizador. Los autores proponen y examinan diversos tipos posibles de cinetica para el proceso.

Issledovanie provodilos' tsirkulyatsionnym metodom. Posle ustanovleniya ravnovesiya v sistemu vvodilos' v kachestve metki maloe kolichestvo S{sup 35}O{sub 2} i izmeryalas' skorost' perekhoda ego v S{sup 35}O{sub 3}. Iz ehtoj skorosti vychislyalas' skorost' pryamogo i obratnogo protsessov okisleniya SO{sub 2} na katalizatore. Predlozheny i obsuzhdeny vozmozhnye skhemy protekaniya protsessa. (author)}
