Title:
BIOGAS FULL-COMPONENT CONVERSION BIOMETHANOL CATALYST LANIO3/SIC-SIO2-FOAM AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/037191
Kind Code:
A1
Abstract:
The present invention relates to a biogas full-component conversion biomethanol catalyst LaNiO3/SiC-SiO2-Foam and method for preparation thereof. In the catalyst LaNiO3/SiC-SiO2-Foam, LaNiO3 is loaded on the carrier SiC-SiO2-Foam, and the loading amount of LaNiO3 is 3%–7%. The LaNiO3/SiC-SiO2-Foam obtained by preparation of the present invention has a perovskite unit cell structure; all nickel and lanthanum elements are arranged in a certain order, and the nickel element in the Ni-La2O3/SiC-SiO2-Foam obtained after reduction is precipitated in a corresponding arrangement order; the dispersibility is high, distribution is uniform, performance is stable, and the conversion rate is high, and the invention can catalyze very well a biogas full-component conversion synthesis gas for use in the synthesis of biomethanol. The preparation method of the present invention has a simple process and low cost, and is easy to commercialize and produce on a large scale.
