The preparation of composite ceramic inorganic membranes using different types of support with the aim to achieving high selectivity for lower hydrocarbons was studied. The pore size of the unmodified support was determined. Upon modification of the support, the morphology was examined using scanning electron microscopy (SEM), which showed a reduction in the pore radius and pore size inorganic ceramic membrane consisting of a ceramic support and a zeolite layer. The permeance of nitrogen, carbon dioxide, helium, methane, propane and argon through the membrane at varying pressures was determined. The effect of the mean pressure of up to 0.1 MPa on the molar flux of the gases at 294K was determined.
