In this work, a new method to prepare Mg-Al-O oxide by co-precipitation method with addition of H2O2 was developed. The application of Mg-Al-O as a support of Pt-Sn catalysts for paraffin dehydrogenation was investigated. Characterization results indicated that modification of H2O2 (i) enlarged the pore structure and decreased the density and mechanical strength of the Mg-Al-O oxide and (ii) increased the platinum dispersion, weakened the acidity of the Pt-Sn/Mg-Al-O catalysts. Dehydrogenation of n-dodecane results showed that modification of H2O2 (iii) improved the paraffin conversion and olefin selectivity; (iv) inhibited the coke deposition on the catalyst and (v) extended the catalyst life-time.
