    The purpose of the present work was to explore the application of solvent assisted spreading to alpha-boehmite instead to gama-Al2O3. It was expected that MoO3 might serve only as deposited active phase but simultaneously also as peptizing agent improving mechanical strength and as thermal stabilizer inhibiting sintering of support surface area during calcination.

    Cílem práce bylo prozkoumat použití metody rozprostírání s asistencí rozpouštědla na alfa-boehmitu namísto gama-Al2O3. Očekávalo se, že MoO3 by mohl sloužit jako nanesená aktivní fáze a zároveň také jako peptizační činidlo, které vylepšuje mechanickou pevnost, a také jako teplotní stabilizátor inhibitující sintraci plochy povrchu nosiče během kalcinace.
