Abstract:The composite catalyst SO 4 2− /ZrO 2 /H-ultra Y zeolite (denoted SZ/HUSY) was prepared and first used in the isobutane/1-butene alkylation reaction. The alkylation performance of the composite catalyst was compared with that of SZ and HUSY. The prepared catalysts were characterized by X-ray diffraction (XRD), Py-IR, NH 3 -TPD, and so on. The experiment showed that high SZ loading destroyed the crystalline structure and morphology of HUSY, while 5% SZ loading could maintain the favorable structure of HUSY and … Show more
