Title:
AMMONIA SYNTHESIS CATALYST
Document Type and Number:
WIPO Patent Application WO/2019/017399
Kind Code:
A1
Abstract:
Provided is an ammonia synthesis catalyst having a configuration in which a catalytic component and a promoter component are supported on a carrier. The ammonia synthesis catalyst is characterized in that: the catalytic component is ruthenium, and the promoter component is an alkali metal or an alkaline-earth metal; and the carrier is a carbon material, in which an inter-layer distance between 002 planes derived from the carbon lamination structure is in the range of 0.339-0.375 nm, the specific surface area is in a range of 150-1400 m2/g, and the average pore diameter is in the range of 8-20 nm, the foregoing all being determined by X-ray diffraction analysis.
