摘要：
The relationship between surface acidity and alkylation reaction catalytic activity of modified Y zeolite was studied on fixed-bed reactor by FT-IR. Results show that the catalyst's activity and life span have no remarkable improvement after ion exchange while they have good performance after adding La2O3, and the B, L acids are decreased.
