TiO2/SiO2 complex supporsys prepared by using gas phase adsorption method and a definite amount of MoO3 is deposited on TiO2/SiO2 by means of impregnation.
采用气相流动吸附法制TiO_2/SiO_2复合载体,浸渍法担载一定量MoO_3。
TiO 2/γ-Al 2O 3 complex support was prepared by gas phase adsorption method and molybdena was deposited on titania-alumina by impregnation of (NH 4) 6Mo 7O 24 ·4H 2O solution.
采用气相流动吸附法制TiO2/γ-Al2O3复合载体,浸渍法担载一定量MoO3用XRD,TPR方法考察MoO3的分散状态,中压固定床反应装置测定催化剂的噻吩加氢脱硫和环己烯加氢活性,结果表明,TiO2的加入能减弱MoO3与γ-Al2O3间的相互作用,促进MoO3的还原,提高催化剂的加氢脱硫活性。
