Abstract

The invention provides a preparation method of a novel hydrogen catalytic combustion non-noble metal catalyst, and belongs to the field of hydrogen catalytic combustion. The preparation method comprises the following steps: taking cordierite Mg2Al4Si5O18 as a carrier; coating a coating slurry prepared by taking gamma-Al2O3 powder as a raw material; preparing a manganese-cobalt-copper-iron-nickel mixed solution according to different manganese-cobalt-copper-iron-nickel atom molar ratios, dipping to obtain 10wt% MnO2-Co2O3-CuO-Fe2O3-NiO / gamma-Al2O3 / cordierite, and preparing a catalyst product through reduction in H2 atmosphere. The non-noble metal supported catalyst containing cobalt, manganese and other elements can be used for replacing a noble metal catalyst, and can solve the problems that the noble metal catalyst in the industry is extremely expensive and is easy to lose at high temperature. The catalyst prepared in the invention can realize catalytic combustion at a low hydrogen temperature and has excellent catalytic performance, heat resistance, stability and economical performance.

Description

technical field [0001] The invention belongs to the field of hydrogen catalytic combustion, and in particular relates to a preparation method of a non-noble metal catalyst and its application in hydrogen catalytic combustion. [0002] technical background [0003] With the continuous consumption of fossil energy, reducing carbon emissions has become an urgent issue. As a clean energy source, hydrogen has attracted widespread attention due to its characteristics of no pollution and no carbon emissions. Its advantages of large reserves and high calorific value provide a basis for its promotion and application. However, hydrogen has a wide explosion limit range, which makes its application conditions very harsh. Therefore, it is necessary to strictly control the combustion rate of hydrogen to ensure the safety of the combustion reaction. Hydrogen catalytic combustion refers to the flameless oxidation process of hydrogen on the surface of the catalyst. It is a complex physical a...
