| Outline of Final Research Achievements |
Development of a pore-through type catalytic membrane where reactions take place in the process of passing through it was attempted. First, in the catalytic membrane preparation, a counter diffusion method was developed to form the catalyst layer inside the porous support. It is because if catalyst is loaded on the outer or the inner surface of the membrane, the reaction starts before the reactant enters the inside of the membrane and therefore the reaction selectivity can not be controlled.
A platinum catalyst layer was formed inside the porous support, and in the model reaction, dehydrogenation reaction of cyclohexane to benzene, improving the selectivity to cyclohexene as an intermediate product was aimed. As a result of conducting the reaction test by applying a differential pressure across the catalytic membrane to make it unidirectional flow, it was clarified that the yield could be improved by suppressing the decrease in selectivity due to the increase in reaction conversion.
