preparation example Construction

[0049] In a third aspect, the present invention provides a method for preparing a catalyst, the method comprising: impregnating the catalyst carrier with a molten solution of a crystalline salt of an active metal component, and then roasting the obtained impregnated material, the impregnated method according to the present invention The catalyst impregnation method described in the invention is carried out.

[0050] In the preparation method of the catalyst of the present invention, no additional water is introduced, so no drying process is required.

[0051] In the preparation method of the catalyst of the present invention, there is no special limitation on the calcination conditions, which can be various conditions commonly used in this field. Preferably, the calcination conditions include: temperature of 500-700° C., time of 1-10 h.

Embodiment 1

[0061] This embodiment is used to illustrate the internal infrared indirect heating equipment, the impregnation method of the catalyst and the preparation method of the catalyst of the present invention.

[0062] Such as figure 1 As shown, the internal infrared indirect heating equipment of this embodiment includes a feed mixing device, a drum turning device, an infrared heating device, a temperature control device and a discharge device,

[0063] Among them, the drum turning device is used to mix the materials placed in the drum, including the drum 1, the elevation angle adjustable bracket 6 and the gear motor 5, the drum 1 is a stainless steel drum, the inner diameter is 550mm, the outer diameter is 556mm, and the length is 4035mm; the elevation angle adjustable bracket 6 is used to adjust the elevation angle of the drum 1, and the geared motor 5 is used to control the rotation speed of the drum 1;

[0064] Wherein, the feed mixing device is used to mix the catalyst carrier...

Embodiment 2

[0077] Using the equipment of Example 1 and according to the method of Example 1, the difference is that in the infrared heating device, the central axis of the support is higher than the central axis of the rotating drum, and the vertical distance between the central axis of the support and the central axis of the rotating drum Distance is 4% of rotating cylinder diameter; In the method, the feeding speed of controlling catalyst carrier and nickel nitrate crystal is 120.5kg / h and 121.3kg / h respectively, and the feeding speed of controlling mixed material is 245kg / h; Adjust rotating drum The rotation speed of the rotary drum is 2.0 rpm, the elevation angle of the drum is 1.7°, and the residence time of the mixed material in the drum is controlled to be 22 minutes; the input power of the infrared heating plate is adjusted so that the temperature of the atmosphere in the drum is 73°C, controlled by the fan The temperature of the outer wall of the drum was 58°C.

Abstract

The invention relates to the technical field of catalyst processing, and discloses internal infrared indirect heating equipment, a catalyst impregnation method and a catalyst preparation method. The internal infrared indirect heating equipment comprises a drum material-flipping device and an infrared heating device, wherein the drum material-flipping device comprises a rotary drum for mixing a material placed in the rotary drum, and the infrared heating device is arranged in the central axis zone of the rotary drum and is used for heating the material in the drum material-flipping device. Thecatalyst impregnation method is performed in the internal infrared indirect heating equipment. With the catalyst impregnation method of the present invention, the adhesion between the material and theequipment can be effectively reduced, the uniformity of the impregnation can be improved, the breaking on the catalyst carrier by the impregnation can be reduced, the wear strength and the reactivityof the catalyst can be improved, and the yield of the catalyst is high.

Description

technical field [0001] The invention relates to the technical field of catalyst processing, in particular to an internal infrared indirect heating device, a catalyst impregnation method and a catalyst preparation method. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and the increasingly stringent environmental regulations, refineries are required to provide more high-quality and clean gasoline products. Clean gasoline has the characteristics of low olefins, low sulfur, and high octane number. my country's gasoline pool is dominated by catalytic cracking gasoline, which has problems such as high olefins, high sulfur, and insufficient octane number. Therefore, the research and development of clean gasoline production technology must consider not only the reduction of olefins, but also the reduction of sulfur, and at the same time ensure the octane number . With the advantages of high desulfurization rate, low oc...
