摘要

The NO_x emission characteristics of the urea selective catalytic reduction (SCR) and solid SCR systems were investigated respectively, through the bench test of a diesel engine equipped with vanadium-based SCR catalyst. The results indicate that solid SCR system wouldn't produce urea crystallization, and can improve the NO_x emission from diesel engine at low-medium exhaust temperature. By use of solid SCR technology the average conversion efficiency is increased by 6% compared with that of urea SCR system especially at exhaust temperature below 300℃. Solid SCR system can be comparable in NO_x conversion efficiency to urea SCR system when exhaust temperature is above 400℃.
