Problems solved by technology

[0013] Based on the above, it can be concluded that BC has high specific surface area, high purity, high mechanical properties, and strong hydrophilicity, which is very suitable as a catalyst carrier, especially for gas-solid phase reactions, but in the prior art BC is rarely used as a catalyst carrier, and the use of BC membranes is mainly concentrated in capacitors, electrodes, and medical products

Abstract

The invention provides a bimetallic SRE ethanol steam reforming hydrogen production monolithic catalyst and a preparation method thereof. The monolithic catalyst has the advantages of high mechanicalstrength, good catalytic performance, high hydrogen selectivity and high catalytic stability.

Description

technical field [0001] The invention relates to a SiO2-CBC catalyst with a high specific surface area. The catalyst is used in the field of gas-solid phase catalytic reactions, and in particular relates to the field of hydrogen production by SRE ethanol steam reforming. [0002] technical background [0003] Finding a clean and efficient energy source has become an urgent problem in today's society. As a non-toxic and efficient clean energy, hydrogen has been widely promoted and used in aerospace, power generation devices such as fuel cells and other fields. At present, there are three main ways to produce hydrogen from biomass ethanol: steam reforming of ethanol (SRE), partial oxidation of ethanol (POX) and autothermal / oxidative reforming of ethanol (ATR). It has the characteristics of high hydrogen content, non-toxicity, easy storage and safe operation, and stands out among many raw materials for hydrogen production. The current reaction formula is: [0004] CH 3 CH 2 O...
