Title

MODELING THE SELECTIVE SEPARATION OF HYDROGEN FROM HYDROCARBON MIXTURE THROUGH AN MFI-TYPE ZEOLITE MEMBRANES

Pages

  35-40

Abstract

 In this work, SEPARATION process of a simulated refinery gas stream of eight components including HYDROGEN and LIGHT HYDROCARBONS C1-C4 through MFI-type zeolite MEMBRANE was studied in a broad temperature range and under different feed-stream pressures. A modified LANGMUIR model is used to correlate the experimental data. SEPARATION results of the zeolite MEMBRANE characterized by the model considering competitive adsorption of hydrocarbons over HYDROGEN and configurational diffusion in the zeolite pores. The bell-shaped flux temperature profile in the temperature range of 25-300 oC is clearly a balanced result of these two opposite driving forces for HC permeation. At a given feed pressure, HYDROGEN flux increases monotonically with temperature. Increasing feed gas pressure shifts the flux-temperature profile toward higher flux direction. At room temperature (25 oC), HYDROGEN flux is almost zero. The selectivity of HYDROGEN had a weak dependence on the feed pressure.
