|1. (WO2017149963) ACTIVATED CARBON, METHOD FOR TREATING ACTIVATED CARBON, AMMONIA SYNTHESIS CATALYST, AND METHOD FOR PRODUCING AMMONIA SYNTHESIS CATALYST|
|Applicants:||MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD.
|Title:||ACTIVATED CARBON, METHOD FOR TREATING ACTIVATED CARBON, AMMONIA SYNTHESIS CATALYST, AND METHOD FOR PRODUCING AMMONIA SYNTHESIS CATALYST|
Provided are activated carbon, a method for treating the activated carbon, an ammonia synthesis catalyst, and a method for producing the ammonia synthesis catalyst such that catalytic activity can be improved over the prior art. Activated carbon is activated by being subjected to heat treatment at a temperature of 800 to 1100°C for 10 to 50 hours in inert gas into which oxygen is mixed in a concentration of 0.05 to 900 ppm, and the activated carbon is used to improve the catalytic activity of an ammonia synthesis catalyst.
