Studying the Effect of Nitric Acid on the Physical Chemistry Properties of the Prepared Extrudates Catalyst Support from Boehmite Powder of Nephleensinite Ore Mines
Abstract: In this research, for the first time, the extrudates
gamma alumina prepared from Boehmite powderof the
Nephleensinite ore mine. In order to enhance the physical
properties of the catalyst support, the prepared extrudats
were treated in high concentration nitric acid at different
times, and the effect of treatment times on the basic
properties as the Surface Area (S.A.) and Average Pore
Diameter (A.P.D.) were studied. These effects were studied
by using X-ray diffraction (XRD), N2-adsorption/desorption
(BET) and Scanning Electron Microscope (SEM)
techniques. The sample 3 with 72 hr aging time was
selected as the optimized sample.
