High-durability metal foam-supported catalyst for steam carbon dioxide reforming and method for preparing the same

摘要

Disclosed is a catalyst support for steam carbon dioxide reforming reaction utilizing the advantages of superior thermal conductivity and thermal dispersion of a metal foam support and a large specific surface area of a carrier material, which allows selective control of coating amount and the thickness of a support layer and prevents cracking on the support surface, using both the sol-gel method and the slurry method that have been used for coating of a metal foam support.

主权项

1. A method for preparing a nickel-based catalyst for steam carbon dioxide reforming comprising nickel as an active metal and washcoated on alumina as a metal foam support, wherein the support has a porosity of 80-97% and 10-110 pores per inch (PPI), the nickel is included in an amount of 0.01-10 wt % based on the support and the alumina is washcoated with an amount of 0.1-30 wt %, comprising:
supporting alumina on a metal foam and sintering; and supporting a nickel precursor on the alumina-supported metal foam support by an impregnation method and sintering again.
