Dimerization of 1-butene in liquid phase was studied over H-Beta zeolite catalyst and MCM-41 mesoporous material in an autoclave at temperature of 473 K and at pressure of 20 bar using n-heptane as a solvent. Liquid phase product analysis was carried out using GC-MS and a pattern recognition technique, Soft Independent Modeling of Class Analogy (SIMCA). Acidity of the catalysts was determined by FTIR, phase purity using X-ray powder diffraction, surface area by nitrogen adsorption and morphology of zeolite and mesoporous material crystals using scanning electron microscope. Influence of acidity, pore size and structure of H-Beta zeolite and H-MCM-41 mesoporous material on the conversion of n-butene and selectivity to C8 hydrocarbon such as 2,2,4-trimethylpentene, dimethylpentene and 2-methylpentene was investigated. H-MCM-41 mesoporous material exhibited higher selectivities to C8 hydrocarbons than H-Beta zeolite catalyst. However, conversion of n-butene was higher over H-Beta zeolite catalyst than H-MCM-41 mesoporous material.
