Title:
複層カーボン・ナノチューブ触媒、その製造方法およびその使用
Document Type and Number:
Japanese Patent JP6495470
Kind Code:
B2
Abstract:
The present invention falls within the technical field of flue gas desulphurization and specifically relates to a multi-walled carbon nanotube catalyst, a preparation method therefor and the use thereof. With regard to the catalyst, a multi-walled carbon nanotube is used as a carrier, and cobalt nitrate and manganese nitrate are catalytically active materials. The preparation method is as follows: modifying the multi-walled carbon nanotubes with nitric acid refluxing, suction filtering and washing same to neutral, then drying, redissolving same into a mixed solution of manganese nitrate and cobalt nitrate, followed by ultrasonic dispersion, drying, grinding and baking under an N2 atmosphere to obtain the multi-walled carbon nanotube catalyst. The catalyst of the present invention is low in amount, easy to recover, and has an outstanding catalytic effect and no secondary pollution, and the catalyst can be widely applied to the oxidation system of the by-product of desulphurization of coal combustion flue gas. In the case where the original oxidizing process is kept basically unchanged, the oxidation rate of sulphite can be increased by above 50%.
