Dimerization of 1-butene in the liquid phase was studied at relatively mild conditions, 523 K under 20 bar over both microporous and embedded microporous mesoporous catalysts. Embedded catalysts were prepared by introducing Beta zeolite nuclei into the gel synthesis of mesoporous material. Three different embedded catalysts with different acidities were prepared and characterized by XRD, nitrogen adsorption, TEM, SEM, pyridine adsorption desorption and ammonia TPD. The embedded materials were shown to be thermally stable up to 1173 K, containing both micro- and mesopores and uniform pores with regular periodicity. According to ammonia TPD the acidity increased with increasing aluminium content. Due to the relatively low reaction temperature, the highest yields of C8 hydrocarbons, 33 mol% at the conversion level of 81% were achieved over an embedded micro-mesoporous catalyst containing Beta zeolite inside the mesoporous and totally 2.4 wt.% aluminium.
