| titleOfInvention | Improvements relating to the manufacture of catalysts |
| abstract | Catalysts are prepared by forming a fluidized bed of porous solid particles at a temperature at which the catalytic material melts and dispersing solid particles of the catalytic material throughout the bed which is maintained fluidized until all the catalytic material is absorbed, some of the porous particles may be introduced together with the catalytic material. Preferably the porous particles are of silica gel and the catalytic material is a glass of vanadium pentoxide and potassium pyrosulphate. Other materials mentioned are:-carrier-alumina, charcoal pumice, zeolites, clays or metallic oxides; catalyst-Ba(OH)2*, Ce(NO3)3*, Co(NO3)2*, Cu(NO3)2*, Cu2Cl2, FeCl3, Mn(NO3)2*, Ni(NO3)2*, H4P2O7, H2PtCl6*, K2Cr2O7, KH2PO4, KHSO4, K2S2O7, Se, AgCl, AgNO3, SnCl2, UO2(NO3)2* and ZnCl2, those marked * being used as crystalline hydrates.ALSO:Ethylene oxide is produced by oxidation of ethylene in presence of a catalyst prepared by dispersing silver nitrate in a fluidised bed of silica gel particles at 220 DEG C., the temperature being afterwards raised to 460 DEG C., the silver nitrate decomposing to silver. Phthalic anhydride is produced by oxidation of naphthalene in presence of a catalyst prepared by dispersing particles of a V2O5/K2S2O7 glass throughout a fluidised bed of silica gel particles at, preferably, 350-400 DEG C., the catalyst being subsequently activated at 420 DEG C. |
