preparation example Construction

[0027] According to the preparation method of the hydrogenation catalyst provided by the present invention, the impregnation temperature is not particularly limited, and may be various temperatures that the impregnation solution can reach. The impregnation time is not particularly limited, as long as the catalyst carrier can be supported with a required amount of hydrogenation active component precursor, the degree of the impregnation is preferably such that the content of the catalyst carrier in the dried hydrogenation catalyst is 60- 95% by weight, preferably 60-90% by weight. Generally, the higher the impregnation temperature, the greater the concentration of the impregnating solution, and the shorter the time required to achieve the same impregnation amount (ie, the weight difference between the impregnated catalyst support and that before impregnated); vice versa. After the required immersion amount and immersion conditions are determined, those skilled in the art can eas...

Embodiment 1

[0046] This example is used to illustrate the hydrogenation catalyst impregnating liquid composition and the preparation method of the hydrogenation catalyst provided by the present invention.

[0047] Mix 13.9 grams of ammonium molybdate, 8.16 grams of nickel nitrate and 10 grams of methylbutenedioic acid (pKa value 2.29, containing two carboxyl groups and a carbon-carbon double bond) and add water to 78 ml. 100 g of the above-mentioned catalyst carrier a was impregnated by saturation method, then dried at 105°C for 2 hours, and then heated to 300°C for 1 hour to obtain 119.6 g of catalyst S1.

Abstract

The invention provides a hydrogenation catalyst soaking solution composition, which comprises a precursor of a hydrogenation active ingredient, a soaking additive and water, wherein the soaking additive has similar pKa value with that of the precursor of the hydrogenation active ingredient and comprises carbon-carbon double bond and / or carbon-carbon triple bond substances in molecular structure. The invention also provides a method for preparing a hydrogenation catalyst, which comprises: using the soaking solution to soak a catalyst carrier, and drying and roasting the catalyst carrier, wherein the soaking solution is the hydrogenation catalyst soaking solution composition. The hydrogenation catalyst prepared from the hydrogenation catalyst soaking solution composition has higher hydrogenation activity and higher cracking activity at the same reaction temperature compared with a hydrogenation catalyst prepared by the prior art.

Description

technical field [0001] The invention relates to a hydrogenation catalyst impregnating liquid composition and a preparation method of the hydrogenation catalyst. Background technique [0002] In recent years, the trend of heavy and inferior crude oil has become increasingly obvious around the world. At the same time, the demand for high-quality gasoline, kerosene and diesel has continued to increase, which has prompted the production of high-quality gasoline, kerosene and diesel using heavy hydrocarbon oil as raw materials The purpose of hydrocracking technology has been developed rapidly, and hydrorefining and hydrocracking catalysts are one of the most important and key factors in the development of hydrocracking technology. [0003] Hydrocracking catalyst is a dual-functional catalyst, which has cracking activity and hydrogenation activity at the same time, that is, it contains acidic components and hydrogenation active components at the same time, and its acidity is mainl...
