Abstract

The invention relates to a yttrium-manganese-nickel perovskite type catalyst for producing hydrogen by autothermal reforming of acetic acid. Aiming at the problem of catalyst deactivation in the autothermal reforming reaction of acetic acid in the existing catalyst, the present invention adopts a hydrothermal method to use Ni as an active component, introduces Y element, and partially replaces Ni by Mn element, forming mesoporous Y (Mn ,Ni)O 3 The perovskite-like structure catalyst improves the dispersion and stability of the active component nickel, and induces the efficient conversion of acetic acid, obtaining a new catalyst with high sintering resistance, coke resistance and high activity. The chemical composition of the catalyst of the present invention is (NiO) a (MnO 2 ) b (YO 1.5 ) c , where a is 0.39, b is 0.61, and c is 0.5.

Description

technical field

[0001] The invention relates to a yttrium-manganese-nickel perovskite structure catalyst used for producing hydrogen by autothermal reforming of acetic acid, and belongs to the field of producing hydrogen by autothermal reforming of acetic acid. Background technique

[0002] Hydrogen is an important chemical raw material, and has the advantages of high calorific value, no pollution, renewable, and wide range of sources. It is regarded as one of the most potential clean energy sources. At present, hydrogen is mainly obtained from fossil energy such as natural gas and coal through steam reforming, but it is limited by the increasing depletion of fossil energy and environmental pollution. Therefore, resource-rich and renewable biomass has received attention. Biomass is pyrolyzed at high temperature to obtain biomass oil, wherein the water phase components are rich in acetic acid, and the weight ratio can reach 30%, which can be used as a cheap raw material for ...
