preparation example Construction

[0036] The method for preparing the catalyst carrier of the present invention further includes cooling the mixture obtained from the hydrothermal treatment to room temperature after the hydrothermal treatment and before solid-liquid separation. The room temperature in the present invention means that the temperature is not subject to special testing and control, and it only needs to be roughly similar to the ambient temperature, generally 10-40°C.

[0037] Preferably, the method for preparing the catalyst carrier of the present invention further includes adding additives before the hydrothermal treatment, so as to further improve the performance of the catalyst carrier. The adding time of the auxiliary agent is not particularly limited, it can be added before or during the mixing reaction of the alkali and the aluminum salt, and can also be added after the gelatinous liquid is obtained. The type of the auxiliary agent is not particularly limited. Preferably, the auxiliary agen...

Embodiment approach

[0041] In the present invention, the preparation method of the hydrodemetallization catalyst is not particularly limited, and conventional preparation methods in the art can be used. According to a specific embodiment of the present invention, the preparation method of the hydrodemetallization catalyst may include the following steps: (1) Dissolving the nickel source and the molybdenum source in deionized water to obtain a nickel-molybdenum mixed solution, the nickel-molybdenum mixed solution The content of nickel as NiO is 2-4% by weight, and as MoO 3 The calculated molybdenum content is 5-7% by weight; (2) at room temperature, the nickel-molybdenum mixed solution is impregnated with the catalyst carrier of the present invention by an equal-volume impregnation method and kept for 8-16 hours to obtain a precursor; (3) The precursor obtained in step (2) is dried in an oven at 70-90° C. for 8-16 hours, and then calcined at 400-600° C. for 3-6 hours. Wherein, the nickel source c...

Embodiment 1

[0046] An aqueous aluminum chloride solution with a concentration of 2M and an aqueous ammonia solution with a concentration of 1M were prepared, and the ammonia solution was added dropwise into the aqueous aluminum chloride solution, so that the pH of the obtained milky white colloidal liquid was 4.5. The resulting gelatinous liquid was transferred to a hydrothermal kettle, placed in an oven, heated to 160°C and kept for 24 hours, and then naturally cooled to room temperature. The reacted product was separated by centrifugation, washed repeatedly with deionized water, and then dried in an oven at 120° C. for 12 hours to obtain a pseudo-boehmite precursor. The obtained precursor was heated to 550°C in the air for 2 hours, and then the obtained solid and peptizer (15% nitric acid) were mixed in a weight ratio of 100:2 and then extruded to obtain the catalyst carrier I1, the properties of which are shown in the table 1.

[0047] Carry out SEM detection to I1, the obtained resul...

Abstract

The invention relates to the field of catalysts, and discloses a catalyst carrier, a preparation method thereof and a hydrodemetalation catalyst containing the catalyst carrier. The catalyst carrier is formed by stacking a plurality of nanorod-shaped aluminum oxide monomers and is provided with open ducts. Each nanorod-shaped aluminum oxide monomer has the length of 100-500 nm and the diameter of 10-50 nm. The catalyst carrier has large pore volume and pore aperture and has good pore properties, permeability and metal capacity. The catalyst carrier is simple in preparation method, free of addition of pore forming materials, plasticizer and other various additives, and low in cost; in addition, the hydrodemetalation catalyst is high in metal capacity and high in activity and stability.

Description

technical field [0001] The invention relates to the field of catalysts, in particular to a catalyst carrier, a method for preparing the catalyst carrier, a catalyst carrier prepared by the method, and a hydrodemetallization catalyst containing the catalyst carrier. Background technique [0002] Recently, with the rapid increase of the number of private motor vehicles, the total demand for vehicle fuel has doubled. Due to the shortage of resources caused by the over-exploitation of crude oil, the heavy and inferior quality of crude oil is becoming more and more serious, which brings severe challenges to the refining process of oil products. Due to the increase in the density of crude oil and the increase in viscosity and impurity content, especially the increase in metal-containing compounds due to the deterioration of crude oil, it may not only have a greater impact on the environment and motor vehicle parts, but also affect the refining process. , Product quality and light...
