Abstract
In the technical approach to meeting the China VI emission standards for heavy-duty diesel vehicles
the active regeneration of diesel particulate filter (DPF) subjects the downstream ammonia selective catalytic reduction (NH
3
-SCR) catalysts to a high-temperature hydrothermal environment. Therefore
developing catalyst with stable comprehensive performance under such conditions holds significant application value. The hydrothermal deactivation mechanisms and stability enhancement strategies of NH
3
-SCR catalysts were systematically reviewed. Firstly
focusing on zeolite catalysts
the synergistic deactivation mechanism caused by hydrothermal aging
which involves framework dealumination
migration and aggregation of active metal species
was analyzed. Subsequently
for metal oxide catalysts
the intrinsic thermal deactivation essence
which includes carrier phase transformation
active phase crystallization and loss of surface active sites was elucidated. Based on this
the main strategies for enhancing hydrothermal stability were summarized
including zeolite composition optimization
additive addition and framework structure regulation. Finally
the development prospects of NH
3
-SCR catalysts with high hydrothermal stabilities in the future were prospected.
