Title:
CATALYST COMPLEX FOR PROCESSING EXHAUST GAS OF LARGE DIESEL ENGINE USING HIGH-SULFUR DIESEL FUEL
Document Type and Number:
WIPO Patent Application WO/2020/076008
Kind Code:
A1
Abstract:
The present invention relates to a multi-functional catalyst complex for processing an exhaust gas, which reduces, via reduction, nitrogen oxide (NOx) occurring in a large engine for a vessel using a high-sulfur diesel fuel, and which, at the same time, has the function of an ammonia oxidation catalyst (AOC) for preventing a leakage of NH3 used as a reducing agent, the catalyst complex comprising an SCR function part in an upper layer, and an AOC function part in a lower layer, wherein the upper layer contains vanadium and cerium sulfate (Ce sulfate) on a first fire resistant metal oxide, and the lower layer contains a platinum metal and vanadium on a second fire resistant metal oxide.
