Ni/La2X2O7 catalyst for hydrogen production by autothermal reforming of acetic acid

Abstract

The invention relates to a Ni / La2X2O7 catalyst for hydrogen production by autothermal reforming of acetic acid. , Aiming at the problem of inactivation of an existing catalyst in the acetic acid autothermal reforming process, the invention provides the novel catalyst which is stable in structure and high in activity. A catalyst precursor is prepared by adopting a sol-gel method, and roasted by adopting an impregnation method to obtain the Ni / La2X2O7 (X is Ce, Zr or Ti) catalyst. According to the catalyst, the stability of active components is improved, the yield of hydrogen is increased, and generation of byproducts such as methane and acetone is effectively inhibited.

Description

technical field

[0001] The present invention relates to a kind of Ni / La 2 x 2 o 7 The application of the (X=Ce, Zr, Ti) catalyst to convert acetic acid, the water phase component of biomass oil, into efficient and clean secondary energy hydrogen by means of autothermal reforming belongs to the technical field of hydrogen production by autothermal reforming of acetic acid. Background technique

[0002] Hydrogen is widely recognized as a clean energy source that can help address pollution emissions, sustainability and energy security. Hydrogen can be obtained from a variety of sources, including non-renewable energy (coal, natural gas, and oil) and renewable energy (biomass, etc.). Hydrogen production from renewable biomass and its derivatives is one of the most promising methods for producing green chemical fuels.

[0003] Biomass has low energy density and can be converted into biomass oil with high energy density after rapid pyrolysis. Biomass oil is viscous and comple...
