英文摘要	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.
