摘要

与氨的选择性催化反应已被建立，以减少在燃气发动机燃烧过程中的氮氧化物排放。催化剂的应用和还原剂的引入是一项重大挑战，尤其是对小型发动机而言。在此工作中，定量测定了商用VWT催化剂在70 kwel沼气汽油机运行17个月后的老化现象。利用空间分辨CFD可以表明，这些对紧凑应用程序的活动性没有影响。

Alterungsstudie an VWT-Katalysatoren für stationäre Biogas-Motoren mithilfe der CFD Aging Study on VWT Catalysts for Stationary Biogas Engines Using CFD

The selective catalytic reaction with ammonia has become established to reduce NO_x emissions during combustion in gas engines. Catalyst application and the introduction of the reducing agent represent a major challenge, especially for small engines. In this work, the aging phenomena of a commercial VWT catalyst after 17 months of operation of a 70-kW_el biogas gasoline engine are quantitatively determined. Using spatially resolved CFD it can be shown that these have no influence on the activity properties of the compact application.
