Breakthrough catalyst wins approval
London, England - Clean Diesel Technologies ( http://www.cdti.com ) announced this morning that the U.S. Mining Safety Health Administration (MSHA) had approved the use of CDT's Platinum Plus(R) fuel borne catalyst (FBC) as part of a diesel particulate filter system supplied by New Mexico-based CleanAIR Systems, for use in underground mines, according to Dow Jones Newswires.
The PERMITTM FBC Filter system uses a catalyzed ceramic filter and CDT's patented FBC to reduce toxic diesel particulate by more than 85%.
The companies will market to U.S. mines through the CleanAIR Systems distributor network and discussions are underway for distribution to overseas mining and tunneling sectors.
CleanAIR Systems designed and tested a precious metal catalyst coating for the filter that does not increase NO2 emissions, one of the major drawbacks to using traditional precious metal catalyst coatings.
The precious metal catalyst also greatly decreases emissions of poisonous carbon monoxide and toxic hydrocarbons and works with the FBC to promote safe filter regeneration or self cleaning of the filter under normal operating conditions.
Besides mining applications, CleanAIR Systems and CDT have recently supplied the combined FBC and after treatment system to refuse trucks, beverage delivery trucks, and stationary engines.
CDT and CleanAIR are also conducting field and engine dynamometer testing in support of verification under the California Diesel Risk Reduction Program.
Recent tests of an on-highway diesel engine resulted in more than 90% reduction in diesel particulate matter (DPM) and no increase in NO2 when the PERMITTM FBC Filter and Platinum Plus FBC were used with ARCO's ECD-1 ultra low sulfur diesel on a 1998 heavy duty diesel engine.
