The Selective Catalytic Reduction Technology (SCRT) System Data Sheet

For diesel applications where maxi-mum NOx reduction is critical, SCR technology provides the highest NOx reduction available today. The SCRT® system is Johnson Matthey’s patented 4-Way emission control technology. JM’s SCRT system reduces all four regulated exhaust emissions: CO, HC, and PM by over 90%, and NOx by 70%.Johnson MattheyCatalystsD iesel Retrofit Emissions Control S olutionsSCRT® Selective Catalytic Reduction Technology33REMOTE DISPLAY MODULESELECTIVE CATALYTIC REDUCTION TECHNOLOGYJohnson MattheyEXHAUST GAS RECIRCULATION TECHNOLOGYJohnson MattheyCATALYZED CONTINUOUSLY REGENERATING TECHNOLOGYJohnson MattheyDIESEL CATALYTIC CONVERTERJohnson MattheyCRT® DIAGNOSTIC MODULECONTINUOUSLY REGENERATING TECHNOLOGYPARTIAL CONTINUOUSLY REGENERATING TECHNOLOGYPARTIAL CONTINUOUSLY REGENERATING TECHNOLOGYJohnson MattheyJohnson MattheyJohnson MattheyPARTIAL CONTINUOUSLY REGENERATING TECHNOLOGYJohnson MattheyJohnson MattheyJohnson MattheyFour-way emission control system that delivers highest NOx reduction across a broad range of applications.Engine ExhaustMeets EPA VErifiEdNO2 Slip RequirementsUrea Injection800-RX-FOR-AIR • 800-793-6724 • HDD@JMUSA.COM©2010 Johnson MattheyD iesel Retrofit Emissions Control S olutionsJohnson MattheyCatalystsHC CO PM NOxTechnology DrivenUrea-based Scr technology is combined with Johnson Matthey’s patented crT® particulate filter system to achieve maximum emission con-trol. First, engine exhaust flows through Johnson Matthey’s crT diesel par-ticulate filter to reduce co, PM, and hc. A controlled amount of urea (DeF) is then injected into the exhaust before it enters the Scr catalyst modules. The urea is converted to ammonia and provides the necessary chemical conditions for the Scr catalyst to reduce nox. The Scr system consists of a commercially available urea injection system, a JM developed control system that precisely delivers urea, and Scr and ammonia slip catalysts.FeATUring• PM, HC, and CO reduction over 90% and 70% NOx reduction.• Air assisted injection for optimum droplet size.• Meets EPA NO2 slip requirements.• Turnkey kit ready for installation.• Well suited to retrofit fleets with central fueling capability.Proven SUcceSSJohnson Matthey’s SCR experience extends back over three decades. JM supports SCR in stationary applications for prime or back-up power, gas turbines and refinery heaters. Additionally, most U.S. engine oe’s have selected JM as their partner for PM/nox control for U.S. 2010 and european engine oe’s have selected Johnson Matthey as their partner for euro 4/5 mobile Scr supply.SCRT® Test ResultsSCRT® Performance on Heavy Duty Dieselhttp://ect.jmcatalysts.comSCRT® Selective Catalytic Reduction Technology% Reduction (G/BHP-HR%) NOx PM2004 Standard 2.5 0.1 2007 Standard 1.2 0.012010 Standard 0.2 0.01SCRT PerformanceFTP Weighted Emissions 0.450 0.005OICA Weighted Emissions 0.050 0.00710080604020.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
