Abstract

The invention relates to the technical field of waste gas adsorbents, and particularly discloses an arsine phosphine special gas adsorbent and a preparation method thereof.The arsine phosphine special gas adsorbent comprises a component A and a component B, and the volume ratio of the component A to the component B is 1: (0.1-0.3); the component A comprises the following raw materials in percentage by weight: nano active copper oxide, active aluminum oxide and silicon dioxide; the specific surface area of the nano active copper oxide is greater than 100m < 2 > / g; the specific surface area of the nano active copper oxide is greater than 100m < 2 > / g; and the component B is aluminum sol. The arsine-phosphine special gas adsorbent obtained in the invention has a specific surface area and a pore volume of 120m < 2 > / g and 0.50 cm < 3 > / g respectively, and has relatively high specific surface area and pore volume; the highest adsorption capacities of arsine and phosphorane are 67 L / L and 117 L / L respectively, and the arsine and phosphorane adsorption capacity of the arsine and phosphorane special gas adsorbent is improved.

Description

technical field [0001] The present application relates to the field of exhaust gas adsorbents, and more particularly, to an arsine phosphine special gas adsorbent and a preparation method thereof. Background technique [0002] Special gas will be generated in the production process of bad plating parts or electroplating hangers in the electroplating industry, chemical polishing of aluminum alloy and stainless steel, silicon wafer processing in the photovoltaic industry, combustion of boilers, brick kilns, and chemical industries. [0003] Special gas, also known as special gas, is a basic chemical raw material with great danger. Most of them are flammable, explosive, toxic and corrosive gases. Therefore, special treatment is required in the production process to reduce the risk of special gas. damage to humans and the environment. Common special gases are chlorine, hydrochloric acid, nitrogen dioxide, sulfur dioxide, phosphine, arsine and volatile organic compounds. Among ...
