英文摘要 | hydroisomerization catalysts pt/zsm-22, pt/zsm-23, and pt/zsm-22/zsm-23 were prepared by supporting pt on zsm-22, zsm-23, and intergrowth zeolite zsm-22/zsm-23, respectively. the typical physicochemical properties of these catalysts were characterized by x-ray diffraction (xrd), n2 absorption-desorption, pyridine-fourier transform infrared (py-ftir), transmission electron microscopy (tem), x-ray fluorescence (xrf), scanning electron microscopy (sem) and nh3-temperature programmed desorption (nh3-tpd), and the performance of these catalysts in n-dodecane hydroisomerization was evaluated in a continuous down-flow fixed bed with a stainless steel tubular reactor. the characterization results indicated that the intergrowth zeolite zsm-22/zsm-23 possessed the dual structure of zsm-22 and zsm-23, and the catalyst pt/zsm-22/zsm-23 had similar pores and weak acidity to pt/zsm-22 and pt/zsm-23 catalysts. moreover, pt/zsm-22/zsm-23 catalyst showed a high selectivity in hydroisomerization of long chain n-alkanes to mono-branched isomers. the evaluation results for n-dodecane hydroisomerization indicated that the activity of pt/zsm-22/zsm-23 was the lowest, while the hydroisomerization selectivity was the highest among the three catalysts. the maximum yield of i-dodecane product was 68.3% over pt/zsm-22/zsm-23 at 320 a degrees c. |
