Реферат:
A study has been made of the changes in texture of pseudoboehmite aluminum hydroxides during the stages of peptization and coagulation in liquid forming of Al2O3 granules. Precipitates obtained at 291-310 K, with the morphology of freshly precipitated pseudoboehmite and with primarily coagulation-type bonds, are readily deaggregated by acid; therefore, it is possible after coagulation, to obtain granules with a uniform pore structure and high strength. With precipitation temperatures of 368-375 K and the formation of crystallization contacts in the hydroxides, treatment with acid does not result in deaggregation. By varying the ratio of the first and second types of precipitate, Al2O3 granules with predetermined structural and mechanical characteristics can be obtained, suitable for supports of exhaustive oxidation catalysts that are used in catalytic heat generators.
