Abstract

In this research work some ceramic membranes with composite structure of Al2O3/SiO2 are synthesized and their performance in production and purification of hydrogen in steam reforming reactor are investigated. These membranes are characterized by SEM, DLS methods. Composite layer of 80-100 nano meter was formed. Permeation of hydrogen is measured as 7-10 *11-8 mol.m-2s-1.pa-1 and selectivity in the rane of 100, 200, 500 with N2, CO2 and CH4 ia obtained. The conversion of methane is raised to 95% in 800 C in a steam reformin reactor. The production of hydrogen in comparison to fixed bed reactor has increased by 30%.
