Zeolite membranes that possess well-defined pores of molecular dimensions as well as good thermal, chemical, and mechanical stability have potential for new separation applications in the petrochemical industry. In this work, we fabricated azeolite membrane to obtain a high purity of ethylbenzene(EB) separating from mixed xylene (ethylbenzene, p-xylene, m-xylene, o-xylene).Various kinds of ZSM-5 precursors were prepared. Using its precursors, zeolite membranes were coated on the alumina tube support, and then fabricatedby using Microwave reactor. Vaporpermeation of EB/mixed xylene through zeolite membranes was performed at specific conditions like temperature, flow and pressure. |
