JOHNSON MATTHEY'S MINING CRT TECHNOLOGY BRINGS LOW-NO_2 PM CONTROL TO THE EXISTING FLEET OF DIESEL ENGINES OPERATING IN THE MINING SECTOR

摘要

Johnson Matthey has developed the first diesel particulate filter (DPF) for underground mining that controls particulate matter (PM) at the same time as maintaining emissions of NO2 at or below engine baseline levels. DPF technology is critical for controlling PM which is classified as a carcinogen, but passively regenerating systems rely on the use of oxidation catalysts that can potentially increase NO2 emissions. This paper reviews the development of low-NO_2 PM control technology and the results from testing this technology underground on diesel mining equipment.
