Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] see as figure 1 Shown, the technical scheme that this specific embodiment adopts is: its production steps are as follows:
[0025] 1. Production carrier: use injection molding machine and forming mold to produce HDPE material into cube porous block products;
[0026] 2. Carrier sensitization pretreatment: first, impregnate the produced carrier with stannous chloride hydrochloric acid solution, so that the carrier surface is loaded with stannous chloride, and then after washing with water, the divalent tin ions adsorbed on the carrier surface are hydrolyzed Form basic tin chloride gel film;
[0027] 3. Carrier activation treatment: impregnate the pre-sensitized carrier with acidified palladium chloride solution, the palladium chloride solution reacts with stannous chloride on the surface of the carrier, and palladium ions are reduced by divalent tin ions on the...

Abstract
The invention discloses a production method of a high-efficiency catalyst for catalyzing organic waste gas combustion, and relates to the technical field of waste gas treatment. The production methodcomprises the following steps: producing an HDPE material into a cubic porous blocky product by an injection moulding machine and a moulding mould; firstly, impregnating a produced carrier with a hydrochloric acid solution of stannous chloride to load the surface of the carrier with the stannous chloride, and then washing with water to hydrolyze divalent tin ions adsorbed on the surface of the carrier into a basic tin chloride gel membrane; impregnating a sensitized pretreated carrier with an acidified palladium chloride solution, performing a reaction on the palladium chloride solution and the stannous chloride on the surface of the carrier, reducing palladium ions as an oxidant by the divalent tin ions on the surface of the carrier to form a nanoscale metal palladium core catalytic center, and allowing chemical plating to occur spontaneously; preparing a plating solution; preparing a finished product. With the production method, the characteristics of light weight, high catalytic efficiency, unlikeliness in attenuation, wear resistance, high plating hardness, a long service life, a wide application environment and the like are achieved, and the practicality is stronger.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a production method of a high-efficiency catalyst for catalyzing the combustion of organic waste gas. Background technique [0002] At present, my country's comprehensive treatment technology for toxic and harmful organic waste gas is relatively backward, and there are still few treatment methods, single application technology, and most of the technologies are immature. There is no suitable treatment technology for organic waste gas in some industries, especially complex organic waste gas containing inorganic substances, dust particles, oil and so on. Regardless of whether the composition of industrial organic waste gas is simple or complex, whether it is suitable or not, the activated carbon adsorption method is basically used, and there is basically no supporting regeneration device. The adsorbent is neither regenerated after saturation, and is rarely replaced becau...
