Abstract

The invention discloses a preparation method of a high-toughness and high-flexibility copper oxide gas desulfurizing agent. The preparation method comprises the following steps of: A, preparing a three-dimensional orthogonal structure prefabricated part, namely weaving fiber filaments into the three-dimensional orthogonal structure prefabricated part by adopting a three-dimensional weaving technology; B, preparing impregnation liquid, namely dissolving 1.9-7.6g of copper oxalate powder into 20mL of water to obtain the impregnation liquid; C, carrying out isopyknic impregnation, namely isopyknically impregnating the three-dimensional orthogonal structure prefabricated part obtained in the step A in the impregnation liquid obtained in the step B for 24 hours; and D, preparing a high-toughness and high-flexibility desulfurizing agent, namely performing high-temperature roasting treatment on the impregnated three-dimensional orthogonal structure prefabricated part obtained in the step C toobtain the high-toughness and high-flexibility copper oxide gas desulfurizing agent. The process is simple, and industrial production of the desulfurizing agent can be realized; and the desulfurizingagent adopts a fiber material with high flexibility and rich porosity as a carrier to construct a multistage micro-pore structure of the desulfurizing agent, so that the adsorption capacity and desulfurization reaction activity of the desulfurizing agent can be improved.

Description

technical field [0001] The invention belongs to the technical field of coal chemical desulfurizer preparation, and in particular relates to a preparation method of a high-toughness and high-flexibility copper oxide gas desulfurizer. Background technique [0002] Coal gas, as the source of power and raw materials in IGCC technology, contains a large amount of sulfide, of which more than 90% is hydrogen sulfide gas. Hydrogen sulfide not only causes corrosion to industrial equipment and poisons catalysts, but also poses a threat to the ecological environment and human health after being discharged into the atmosphere. Therefore, the hydrogen sulfide must be removed from the gas before it is used. [0003] Coal gas desulfurization technology includes wet desulfurization and dry desulfurization methods. Wet desulfurization technology has a large processing capacity and relatively mature technology, but this technology has disadvantages such as low efficiency of gas sensible hea...
