Embodiment

[0047] 1γ-Al 2 o 3 Determination of adsorption capacity

[0048] The saturated adsorption capacity of the carrier needs to be determined before preparing the supported catalyst by the equal volume impregnation method. The method is as follows: Then weigh 5.00 grams of carrier γ-Al 2 o 3 , add distilled water dropwise to saturation, the amount of water used (3.5ml) is the saturated adsorption capacity Vp of the carrier (unit: mL / g).

[0049] 2 Catalyst preparation with different components

[0050] FeN 3 o 9 9H 2 O is an active component, wherein the amount concentration ratio (Table 3) of the prepared substance is: n(Fe):n(Al)=0.02:1, 0.04:1, 0.06:1, 0.08:1, 0.1:15 single-supported catalyst. Number the five kinds of active components and carrier mixtures separately and seal them with plastic wrap, soak them at room temperature for 6-8 hours, put the soaked samples in a drying oven at a controlled temperature of 120°C and dry them for 6-7 hours. The process requires st...

Abstract

The invention discloses a catalyst used for preparing anthraquinone through an anthracene oxidizing process and a preparation method thereof. In the invention, Fe-gamma-Al2O3, Zr-gamma-Al2O3 mono-supported catalysts and an Fe-Zr / gamma-Al2O3 dual-supported catalyst can be prepared through an equivalent-volume impregnation method, gamma-Al2O3 being a carrier and iron and zirconium oxides being active components; products are analyzed through an ultrahigh performance liquid chromatograph to analyze the catalytic performance of the catalyst in a reaction of synthesizing the anthraquinone through the anthracene oxidizing process; and the catalyst is represented via means such as XRD, etc. In the invention, development on a solid phase catalyst is attempted, so that the anthraquinone can be prepared through the anthracene catalytic oxidizing process under normal pressure at low temperature (70 DEG C). The catalyst is low in energy consumption and cost and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of catalysts, in particular to a catalyst for preparing anthraquinone by an anthracene oxidation method and a preparation method thereof. Background technique [0002] Anthraquinone (C 14 h 8 o 2 ) is an important fine chemical and chemical intermediate. It is usually used in industrial fields such as the production of anthraquinone dyes, high-concentration hydrogen peroxide, and enhanced kraft paper production processes, and is even widely used in pharmaceutical fields such as medicine and pesticides. Among them, anthraquinone is the parent substance of a large class of dyes and pigments, and occupies a very important position in the field of synthetic dyes. With the diversification and continuous growth of the fine industry, the demand for anthraquinone products in the domestic and international markets has been showing a steady increase. In view of the huge potential market demand of anthraquinone, o...
