Beta zeolite catalysts with different crystal sizes and similar acid strengths were synthesized in a "Steam-Assisted conversion (SAC)" technique. Pt loaded H-beta with an optimized crystal size of 600 nm showed high activity for hydrotreatment of tetralin by producing alkylbenzenes through area and low coke deposition. Isomerization reaction, which was expected to occur on the zeolite surface, was reduced considerably since tetralin interacted with strong Brönsted acid sites as soon as it penetrated the pore of the zeolite and underwent cracking to form linear hydrocarbons, C6 and C7 aromatics products. The method of supporting platinum on the zeolite had a significant effect on the activity of catalyst. For loading platinum of beta zeolite, ion exchange was a suitable method as it helped in well dispersion of platinum on the zeolite surface and inside the micropore.
