摘要：

Potassium modification significantly improved the selectivity and durability of NaY zeolites during lactic acid dehydration reaction. The selectivity of 2.8K/NaY zeolites improved from 14.8% to 50.0% over NaY catalyst. Adding potassium also prolonged catalyst life. After 22 h the acrylic acid selectivity of NaY zeolites reduced to less than 10.0% while that of 3.5K/NaY retained 35.6%. Characterizations with NH3-TPD, CO2-TPD, N-2 adsorption and thermal analysis techniques revealed that the enhancement of catalytic performances could be attributed to the tuned acidity/basicity and the potassium electronic promoter effect.
