Urea hydrolysis reactor for selective catalytic reduction

摘要

#$%^&*AU2015221463B220190822.pdf#####ABSTRACT This disclosure features a urea conversion catalyst located within a urea decomposition reactor (e.g., a urea decomposition pipe) of a diesel exhaust aftertreatment system. The urea conversion catalyst includes a refractory metal oxide and a cationic 5 dopant. The urea conversion catalyst can decrease the temperature at which urea converts to ammonia, can increase the urea conversion yield, and can decrease the likelihood of incomplete urea conversion.
