Title (EN) A METHOD OF INVESTIGATION OR CONTROL OF CATALYSTS OR CATALYST REACTIONS
(FR) PROCEDE D"ANALYSE DE CATALYSEURS OU DE CONTROLE DE REACTIONS CATALYTIQUES
Abstract:
(EN) A method of investigation or control of catalysts or catalyst reactions wherein a gas or gas mixture is brought into contact with the catalyst (12). The properties of the catalyst and/or the progress of the reaction depending on the catalyst are determined or controlled by applying an electric field between the catalyst (12) and an electrode (10) which is arranged in the gas atmosphere spaced from the catalyst. The size of a corona current thereby produced between the catalyst and the electrode is measured and/or adjusted.
(FR) Procede d"analyse de catalyseurs ou de controle de reactions catalytiques dans lequel un gaz ou un melange de gaz est mis en contact avec le catalyseur (12). Les proprietes du catalyseur sont determinees, et/ou le deroulement de la reaction dependant du catalyseur est controle, en appliquant un champ electrique entre le catalyseur (12) et une electrode (10) qui est disposee dans une atmosphere gazeuse a une certaine distance du catalyseur. Le courant de decharge corona se produisant entre le catalyseur et l"electrode est mesure et/ou regle.
