Catalytic Isomerization of n-hexane over Beta (BEA) zeolite synthesized by dry gel conversion (DGC) and hydrothermal (HTS) methods were studied. The isomerization was influenced by types of synthesized methods, and combined selectivity for branched alkanes (2- and 3-methylpentanes, 2,2-dimethylbutane, 2-, and 3-methylbutanes, 2,2-dimethylpropane, and 2-methylpropane) decreased in the order: BEA (DGC) > BEA (HTS). BEA synthesized by DGC had the highest activity and selectivity for the isomerization, and BEA Synthesized by HTS has the highest activity for cracking to lower alkanes and alkenes. These differences are ascribed to the difference of surface area, pore volume, acid properties, and reaction parameters.
