Nghiên cứu phản ứng ankyl hóa benzen bằng etanol trên xúc tác zeolit y biến tính

This paper presents the benzene alkylation with ethanol catalysed on the Y and ZSM-5 zeolite. The experimental results have shown that 30%H-ZSM-5/HY sample is the best for forming ethylbenzene. On this sample the reaction has been carried out by central composite orthogone design at the second level for three factors reaction temperature, flow speed and the molar ratio of ethanol/benzene. The target function for the productivity of ethylbenzene has been yielded. By checking the experimental and mathematic results we observed that current equation is suitable.
