Title:
CATALYST FOR OXIDATIVE DECOMPOSITION AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2019/027057
Kind Code:
A1
Abstract:
The present invention pertains to: a catalyst obtained by supporting a complex of platinum and ruthenium (a PtRu complex) on porous silica, or a catalyst obtained by supporting a stacked complex of platinum and a transition metal TM (a Pt/TM stacked complex) on porous silica, wherein the catalyst is used in order to oxidatively decompose ethylene or a mercaptan compound in the presence of oxygen; a method for oxidative decomposition of ethylene or a mercaptan compound, the method involving bringing ethylene or a mercaptan compound and the catalyst into contact in the presence of oxygen and then oxidatively decomposing the ethylene or mercaptan compound; and a freshness-preserving agent for a food product, the freshness-preserving agent including the catalyst, wherein the freshness-preserving agent is used for preserving the freshness of the food product through being present together with the food product in the presence of oxygen. The present invention provides a catalyst that has the capability to decompose ethylene or mercaptan compounds, the catalyst being less expensive due to a reduction in the amount of platinum used and surpassing conventional silica-supported platinum catalysts.
