Preparation And Performance Of Supported Heteropoly Acid Catalysts

As a kind of polynuclear inorganic macromolecule compound containing oxo bridge, heteropoly acid were the oxygenic polyatomic acid that coordinated with center atom (P、Si、 As、Ge etc.) and coordinating atom (Mo、V、W etc.). Heteropoly acid have pseudo liquid phase because of it’s unique cage structure, catalysis can be carried from not only in the surface but also in the body, so heteropoly acid have good catalyzed activity and selectivity. Loading heteropoly acid on some porous solid carriers can increase specific area which is good for heterogeneous catalysis. This made for heteropoly acid have widely appliance. In this paper, supported heteropoly acid catalyst is prepared by soaking contour which inspected the influences of equipping conditions on catalysis. Supported heteropoly acid catalysts are tested in the light gasoline etherification, which showed that the catalyst of NagGeW11O39loading on activated carbon have good catalytic property for light gasoline etherification.
