title = "Effect of intercrystalline pores in MFI zeolite membranes on xylene separation and membrane improvement by online coking",
abstract = "A mathematical model was developed to quantitatively analyze the xylene fluxes through the nonselective intercrystal pores during permeation of xylene vapor mixtures and estimate the decreases in xylene permselectivity and separation factors caused by such leaking through the intercrystal pores. The theoretical analysis was based on the experimental data of xylene single component permeation and vapor mixture separation. Tubular MFI-type zeolite membranes synthesized by in-situ crystallization from an Al-free precursor were used. A new method of online membrane modification by carbonization of 1,3,5-triisopropylbenzene in the feed stream was developed and found to be effective for reducing the intercrystalline pores and improving the p-xylene separation. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).",
