In the production process of general chemical plants, it is often necessary to use a large number of catalysts to catalyze the reactants, so that the chemical reaction can be completed smoothly and the production efficiency of the product can be increased. Yet because the consumption of catalyzer is very big, and the effect of catalyzing can lose gradually after the catalyzer is used for a period of time, then must change new catalyzer at this moment, and after catalyzer is loaded and unloaded to a carrier (as packaging bag, storage case, tank (car or storage tank, etc.), the catalyst is usually directly poured into the carrier, so the catalyst will easily leak into the working environment, thereby causing environmental pollution and affecting the health and safety of workers. Among them, since catalysts are used to catalyze substances in chemical reactions to improve reaction efficiency, the particle size of catalysts is usually very small to increase the surface area to improve reaction efficiency, so that most catalysts are in the form of particles or powders, which are particularly easy to Leaked out during transportation.
