CARB Extends, Modifies Johnson Matthey's AdvCCRT(TM) Verification, Boosting
Level 3+ PM Reduction Flexibility
AUDUBON, Pa., Nov. 27, 2012
AUDUBON, Pa., Nov. 27, 2012 /PRNewswire/ --The California Air Resources Board
(CARB) has extended and modified its verification of Johnson Matthey's
A[dv]CCRT™ system, a ruling that will provide even greater flexibility to end
users requiring Level 3+ PM reduction.
Initially verified for a duty cycle requiring 230 degree C for 40 percent of
the cycle, the latest extension now allows for not only the original
temperature profile, but also adds a second optional duty cycle allowing use
for applications that meet 300 degree C for 10 percent of the duty cycle.
Marty Lassen, Johnson Matthey's Director of Commercial Development and
Marketing, said, "This is a major improvement in flexibility for users of our
A[dv]CCRT system, the most cost-effective and robust Level 3+ filter system
"In addition, CARB has approved our swapping and re-designation polices, which
allow users significant flexibility in managing their fleets to comply with
CARB's Diesel Risk Reduction Rule requirements," Lassen added.
The A[dv]CCRT system is Johnson Matthey's second generation CCRT^® heavy-duty
diesel retrofit system optimized for more challenging applications. The system
with that advanced catalyst optimization requires no supplemental heat source
and is verified to reduce PM by more than 90 percent for 2002-2006 2.5g NOx
EGR and non- EGR engines. It also meets the stringent NO slip requirements
of CARB and the EPA, which also verified A[dv]CCRT technology.
The A[dv]CCRT system incorporates a unique two-stage filter arrangement. The
first stage duplicates Johnson Matthey's patented CCRT^® filter's pre-catalyst
and coated filter with proprietary catalyst formulations to reduce PM. The
second stage reduces excess NO with the injection of a tiny amount of
hydrocarbon across a decomposition catalyst that converts NO back into NO.
Other systems reduce NO in the filter limiting their ability to reduce PM
in all applications.
