Abstract

The invention provides a capturing agent for rubber particles in butadiene rubber dry waste gas and a preparation method of the capturing agent. The capturing agent is prepared from 60 to 88 weight percent of silicon source, 5 to 20 weight percent of aluminum source, 2 to 15 weight percent of composite carbon, a pore forming agent accounting for 3 to 8 weight percent of the total weight of the silicon source and the aluminum source, and a silica sol binder accounting for 1 to 3 weight percent of the total weight of the silicon source and the aluminum source, wherein the average pore size of the silicon source is 8.0 to 20.0 nm, the specific surface area of the silicon source is 300 to 500 m<2> / g, and the pore volume of the silicon source is 0.8 to 1.5mL / g; the pore volume of the aluminum source is 0.5 to 1.0 mL / g, and the specific surface area of the aluminum source is 200 to 300 m<2> / g; the pore volume of pores greater than 50nm of the composite carbon accounts for 35 percent or above. The invention further provides a preparation method of the capturing agent. According to the capturing agent provided by the invention, particulates such as the rubber particles in the butadiene rubber dry waste gas can be effectively removed, and removal rate can reach 99.9 percent or above.

Description

technical field [0001] The invention relates to a trapping agent for trapping rubber particles in butadiene rubber drying waste gas and a preparation method thereof, belonging to the technical field of waste gas treatment. Background technique [0002] With the rapid development of my country's industry, a large amount of waste gas is produced in the process of industrial production. Industrial waste gas emissions have seriously affected people's living environment and quality of life. In recent years, the frequent occurrence of smog in my country is directly related to industrial waste gas emissions, especially the volatile organic compounds (VOCs). Volatile organic compounds can participate in the formation of aerosols and photochemical smog in the atmosphere, and their effective control has become an important part of atmospheric science research. [0003] The exhaust gas produced in the production process of butadiene rubber contains many rubber particles and solvent o...
