Catalytic reactions are the basis of many chemical and petrochemical processes. They are used, for example, in ammonia synthesis or in oil refineries to produce petrol. In heterogeneous catalysis, the catalyst and the substances required for the reaction are present in different phases: Reactants are usually liquid or gaseous, while a solid substance is often used as catalyst. Different measuring methods are available for the characterization of the corresponding catalysts. Instruments of the RuboCAT series enable reliable and flexible characterization with all common methods.
