摘要：
In the current study the performance of different substrates with respect to pressure drop, mixing between catalyst channels and urea conversion efficiency were measured. An increase of the volumetric conversion efficiency was found when structured substrates were applied. Also the use of solid-urea aerosol was compared to the AdBlue technology and found to be a promising alternative.
