Реферат: This chapter presents the catalyst test methods for quality control of industrial catalysts, the improvement of test methods, and the development of new catalysts. Most catalytic processes are carried out under steady state conditions with essentially constant catalytic properties. Therefore, during tests the steady state reaction conditions conforming to a given temperature and reaction mixture composition must be achieved. For these processes a gradientless method is recommended for measuring the activity with rapid circulation of the reaction mixture. This method permits direct measurement of the reaction rate, excluding the effects of external diffusion and nonuniform flow of the reaction mixture through the catalyst bed. For catalyst evaluation, measurements are carried out at average rates of conversion, sufficiently far from equilibrium. Regulation of component feed, temperature, and the choice of sample for analysis are automated. Computers are used for the calculation of results. In the case of complex multi-path reactions, the most advantageous scheme involves feedback between the computer and the operating unit to control variations in parameters.
