SAPO-34 MEMBRANES OF HIGH FLOW AND SELECTIVITY FOR CO2 / CH4 SEPARATIONS. |
abstract |
SAPO-34 membrane and methods for its preparation and use are described. SAPO-34 membranes are prepared by contacting at least one surface of a porous membrane support with a synthesis gel. The Si / Al ratio of the synthesis gel can be from 0.3 to 0.15. SAPO-34 crystals are optionally applied to the surface of the support before synthesis. A layer of SAPO-34 crystals is formed on at least one surface of the support. SAPO-34 crystals can also be formed in the pores of the support. The SAPO-34 membranes of the invention may have improved selectivity for certain gas mixtures, including mixtures of carbon dioxide and methane. |
