✦ Synopsis

Essen, Federal Republic Of Germany assigned to Bergwerksverband GmbH Use of activated carbon for reduction of nitric oxides with ammonia from exhaust gases using ammonia as reduction agent in the temperature range between 90 degrees-150 degrees C. made from hardcoal, blended with binding agents like pitch, bitumen, tar or tar oil, shaped and subjected to low-temperature carbonization with a heating rate of 20 degrees-100 degrees C./min to temperature between 700 degrees-900 degrees C. in an atmosphere containing 2-5x by vol. of oxygen, so that for the activated coke 2-8x of volatile matter and a surface of 20-l 50 am2/g is arrived at.
