| Popis: | Continuous and high catalytic performance TS-1 zeolite membranes were rapidly prepared on the porous mullite support by dilute precursor synthesis solution. Influences of synthesis conditions (such as molar composition of precursor synthesis solution, crystallization time, and titanium source) on the growth and catalytic activity of TS-1 zeolite membrane for iso-propanol oxidation were systematically studied in this work. When H2O/TPAOH and H2O/SiO2 ratios of the precursor synthesis solutions were 1200 and 300, the inter-growth TS-1 zeolite membrane layer could be formed on the support surface. The TS-1 zeolite membrane was coupled with the oxidation of iso-propanol and hydrogen peroxide by pervaporation, when the reaction temperature and initial ratio of the iso-propanol and hydrogen peroxide were 343 K and 1:2, the iso-propanol conversion and flux of the TS-1 zeolite membrane were 97.62% and 2.45 kg/m2·h, respectively. |
