Abstract

The invention relates to a cobalt-cerium-manganese composite oxide solid solution catalyst for hydrogen production by autothermal reforming of acetic acid. Aiming at the problem of catalyst deactivation of an existing catalyst in an acetic acid autothermal reforming reaction, the invention provides an efficient and stable new catalyst. The chemical component of the catalyst provided by the invention is (CoO1.5) a (CeO2) b (MnOx) c, wherein a is 0.15 to 0.19, b is 0.41 to 0.72, and c is 0.09 to 0.44. Co is used as an active component, Ce and Mn are introduced by adopting a coprecipitation method to form the Co / Ce-Mn-Ox composite oxide solid solution catalyst, generation of byproducts such as acetaldehyde and acetone in the reaction process is effectively inhibited, and the yield of hydrogenand the carbon deposition resistance, sintering resistance and oxidation resistance of the catalyst are improved.

Description

technical field

[0001] The invention relates to the application of a cobalt-cerium-manganese composite oxide catalyst in hydrogen production by autothermal reforming of acetic acid, belonging to the field of hydrogen production by autothermal reforming of acetic acid. Background technique

[0002] At present, most of the fuels used around the world are still fossil fuels, which has brought about environmental pollution problems. Hydrogen is considered as an important clean secondary energy because of its high combustion calorific value, wide range of sources, and environmental friendliness. Hydrogen production from biomass is one of the important ways to sustainably obtain hydrogen from nature. However, the energy density of biomass is low, so biomass is usually pyrolyzed into biomass oil with high energy density, easy storage and transportation. Biomass oil includes oil phase and water phase, and acetic acid is the main component of complex water phase products, so acetic...
