Abstract: A series of β zeolite with various particle sizes were hydrothermally synthesized and characterized in detail. In the alkylation of isobutane with butene the activities of the catalysts increase with the the particle size of the zeolite decreasing(40 μm-20 nm). The selectivity for C 8 decreases with the the particle size of the zeolite decreasing.

Key words: β-Zeolite, Size of the catalyst, NH3-TPD, Alkylation
