Title:
HIGHLY ACTIVE DRY REFORMING CATALYST, AND PREPRATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/003225
Kind Code:
A1
Abstract:
Disclosed are a dry reforming catalyst having high activity and long-term stability, and a preparation method of the dry reforming catalyst. Silica particles having pores are formed by performing a sol-gel reaction on the surface of a micelle-type sol-gel reaction catalyst. Further, catalyst particles of nickel or nickel oxide are formed in the gaps or pores of the silica by means of a solubility differential when the silica is in a gel state.
