Abstract

The embodiment of the present invention relates to a preparation method of a blast furnace slag-supported catalyst, comprising: obtaining blast furnace slag powder; preparing a mixed solution by using active components and absolute ethanol; placing the blast furnace slag powder in the mixed solution, using The magnetic stirrer is continuously stirred at 80° C. for 4-10 hours until the blast furnace slag powder forms a colloid, and the colloid is dried and calcined to obtain a blast furnace slag-supported catalyst. Therefore, the preparation cost is low, the process is simple and easy to control, no treatment steps such as acid hydrolysis are needed, and secondary pollution is effectively avoided. The blast furnace slag is used as a catalyst carrier as a whole, and various components contained in it can be effectively utilized to realize resource utilization and high-value utilization, broaden the resource utilization of blast furnace slag, and achieve the purpose of treating waste with waste. The blast furnace slag-loaded catalyst prepared by the invention has high low-temperature activity and can maintain high CO catalytic removal efficiency in the temperature range of >150°C.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of converter gas treatment, and in particular to a preparation method and application method of a blast furnace slag-supported catalyst. Background technique [0002] Blast furnace slag is the main solid waste produced in the blast furnace ironmaking process of the metallurgical industry, but in terms of its composition, it can be used as high-quality raw materials in the fields of building materials and chemicals. The annual output of blast furnace slag in my country is about 250 million tons. However, most of the existing technologies have the problems of low added value of products and high energy consumption in the recycling process, resulting in poor market competitiveness of resource-based products. , The level of energy utilization is still very low. Therefore, it is of great practical significance to develop a new technology for the comprehensive utilization of blast furnace...
