Outline of Final Research Achievements

Silicoaluminophosphate, SAPO-34 and zeolite A crystals were dissolved in a H2SO4 solution and spin-coated on an alumina plate. The membrane shows high-separation factor for hydrogen/propane (130). The NMR results show that the obtained membranes must be composed of silica and a part of SAPO-34 framework. And water-soluble sulphate salts nanoparticles formed by decomposition of SAPO-34 and zeolite A must be embedded in the aggregate of SAPO-34 framework and silica-newtworks.
