HONEYCOMB CATALYST AND CATALYTIC REDUCTION METHOD

摘要

Honeycomb catalyst structures and methods of using them, where the structures have honeycomb channel walls of selective catalytic reduction catalyst, the channel walls occupy at least 20% of the volume of the structure, the structure exhibits a pressure drop for flowing air not exceeding about 110 Pa at a space velocity of 20,000 hr-1, and the channel walls are of a thickness insuring high degree of catalyst utilization and NOx conversion efficiency.
