英文摘要	Deactivation of a low temperature selective catalytic reduction (scr) catalyst, 1 wt% v2o5/ac, by potassium chloride (kcl) is studied using bet and pore size distribution measurements, nh3 sorption and temperature-programmed desorption (tpd), temperature-programmed surface reaction (tpsr). results show that kcl deactivates 1 wt%v2o5/ac's scr activity and the deactivation become severer at higher kcl loadings. the deactivation is not caused by pore plugging but by neutralization of acid sites on v2o5/ac. weak acid sites are responsible for nh3 activation and scr of no, and are preferentially deactivated by kcl.
