Notes:
Due to the need for CO2 sequestration associated with H2 production from fossil fuels,zeolite membrane are very promising due to their low cost, high stability and high permeance.Recently, the faujasite(FAU), the silica/aluminophophate(SAPO-4) framework family of zeolitehave been studied for CO2 gas separation. In our study, ZSM-5 membrane was prepared on theporous alumina support using a hydrothermal technique. The thickness of zeolite membrane wascontrolled by the hydrothermal reaction time and temperature. The prepared zeolite membraneswere characterized with SEM and thin film XRD. The hydrogen permeability and selectivity towardcarbon dioxide gas were 0.6x 10-6 mole/m2.s.pa and 3.16, respectively. The hydrogen selectivezeolite membranes show promising application in hydrogen separation from coal gasification suchas Integrated Gasification Combined Cycle (IGCC)
