    摘要： THE HYDRODESULFURIZATION OF A HYDROCARBON OIL WITH A CATALYST COMPRISING A SUPPORTED GROUP VI AND GROUP VIII METAL IS IMPROVED BY SODIUM PROMOTION OF THE CATALYST. THE IMPROVED EFFECT IS SUPRISING BECAUSE OVER AN EXTENDED INITIAL STAGE OF THE PROCESS THE SODIUM ACTS AS A CATALYST POISON AND DEPRESSES CATALYST ACTIVITY. HOWEVER, AFTER A PERIOD OF AGING THE HYDRODESULFURIZATION ACITIVTY OF THE SODIUM-PROMOTED CATALYST EMERGES SUPERIOR TO THAT OF THE NON-PROMOTED CATALYST. THE SUPERIOR ACTIVITY OF THE AGED SODIUM-PROMOTED CATALYST IS INEXPLICABLE IN VIEW OF THE FACT THAT THE CARBON, SULFUR AND METALS LAYDOWN ON THE AGED SODIUM-PROMOTED CATALYST IS ABOUT AS HIGH AS ON THE AGED NON-SODIUM-PROMOTED CATALYST.

    摘要： The present invention discloses a sulfur tolerant carbon monoxide shift conversion catalyst, prepared by the following materials: magnesium source, aluminum source, oxide flux, crystal growth agent, rare earth additive, CoO, MoO3 and an acidic aqueous solution. A preparation method of the catalyst is provided, comprising the steps of: S1, Adding an aqueous acidic solution and a specific amount of rare earth additive to a specific amount of magnesium source, aluminum source, oxide flux and crystal growth agent, followed by kneading to produce a mixture; S2, Extruding the mixture to obtain an extruded strip product; S3, Drying the extruded strip product to give a semi-finished product; S4, Calcining the semi-finished product to obtain a catalyst carrier; S5, Impregnating the catalyst carrier with the active components CoO and MoO3 by an incipient-wetness impregnation method to obtain an impregnated product; and S6, Calcining the impregnated product to obtain the catalyst. The oxide flux and crystal growth agent can participate in a solid phase reaction between the magnesium source and aluminum source to form spinel structure, thereby improving the mechanical strength and stability of the spinel. The nano-sized active component can effectively improve the dispersion of the active component, and improve the catalytic activity of the granular boundary of the active component.
