Small evaluation apparatus for activity of catalyst

Abstract

The invention provides a small evaluation apparatus for the activity of a catalyst. The small evaluation apparatus comprises a catalytic reaction zone and a reaction control zone. The catalytic reaction zone comprises a reaction zone shell, a base support, a photocatalytic excitation light source, an aeration head, an aeration pipe, a liquidometer, a catalyst adding opening, an acid / alkali adding opening, a water inlet and a sampling opening; and the reaction control zone comprises a switch, a light intensity controller, a temperature controller, a magnetic agitation speed controller, an air flow meter and a pH meter. Catalytic reaction conditions are set by adjusting each controller in the reaction control zone; the catalyst and a simulation and evaluation catalysis liquid are fully mixed under the action of aeration air-flow or magnetic stirring so as to form a suspension system; and the suspension system can select dark catalytic reaction or light-catalyzed reaction according to the characteristics of catalytic reaction. According to results of the catalytic reaction of the simulation and evaluation catalysis liquid, the activity of the catalyst can be effectively evaluated and a high-activity catalyst can be screened. The small evaluation apparatus provided by the invention has the advantages of portability, small size, easiness in operation, conservation of time and energy, and high efficiency.

Problems solved by technology

At present, the evaluation and screening of catalyst activity are mainly carried out by self-made simple equipment in the laboratory. This evaluation method is single, and the evaluation by simple experimental equipment cannot effectively control the factors that affect the catalytic activity, resulting in the inability to objectively evaluate the catalyst. However, the existing catalyst activity evaluation devices on the market are usually expensive, consume a lot of energy, have complex structures, and occupy a large area, which is not conducive to the wide use of laboratories for catalyst activity evaluation.
