Abstract

The invention discloses a compound. The compound is prepared from copper-supported alumina, zirconium sulfate and a compound metal oxide NdCoO3-y with a perovskite structure, wherein y is oxygen vacancy; the weight ratio of the copper-supported alumina to the zirconium sulfate in the compound is (8 to 1) to (2 to 1); the weight ratio of the copper-supported alumina to the compound metal oxide NdCoO3-y with the perovskite structure in the compound is (10 to 1) to (5 to 1); and by taking the weight of the copper-supported alumina as reference, the content of the copper is 5 to 25 weight percentcounted by oxide. The preparation method of the compound comprises the following steps: mixing, kneading and molding the copper-supported alumina, the zirconium sulfate and the compound metal oxide NdCoO3-y with the perovskite structure, drying and calcining to obtain the compound. The compound has the advantages of high activity, low reaction temperature, simple preparation method, low cost and the like when being used for coalbed methane deoxygenation.

Description

technical field [0001] The invention relates to a compound and its preparation method and application, in particular to a low-temperature high-activity coal gas layer deoxidation composite catalyst and its preparation method and application. Background technique [0002] my country is a big coal producing country, and a large amount of coalbed methane with different concentrations will be produced every year due to coal production. Developing effective coalbed methane utilization technology and reducing direct methane emissions are the key to building an energy-saving and environmentally friendly sustainable development model in my country and creating a low-carbon economy. an integral part of the system. Combining energy conservation and emission reduction and the improvement of environmental requirements, effectively and reasonably develop coalbed methane, a low-grade energy source, and convert it into usable resources, expand the scope and scale of coalbed methane use, and...
