preparation example Construction

[0068] In some more specific embodiments, the preparation method of the fluidized bed hydrogenation catalyst comprises:

[0069] 1) The commercially available basalt fiber chopped yarn is further chopped to a length of about 5 ~ 10 μ M fiber, spare;

[0070] 2) Drying and crushing the natural sponge to obtain the natural sponge powder;

[0071] 3) Mixing the aluminum hydroxide dry rubber powder with the basalt fiber chopped yarn obtained in step 1) and the natural sponge powder obtained in step 2) evenly, adding the extrusion aid, extruding, forming, drying and roasting to obtain the carrier;

[0072] 4) A mixed liquid is formed by adding a non-ionic surfactant to the aqueous solution of the precursor of the metal active component. The precursor of the metal active component is selected from the water-soluble compound containing group VI B and / or group VIII metal elements, and the metal active component is selected from the metal oxide. Then, the carrier obtained in step 3) is i...

Abstract

The invention discloses a method for producing clean fuel from full fractions of coal tar. The method comprises the following steps: distilling whole fractions of coal tar to obtain heavy fractions and light fractions, then carrying out alkali washing and acidification treatment on the obtained light fractions to obtain coarse powder and dephenolized oil, and meanwhile, carrying out hydrotreatment on the obtained heavy fractions in a fluidized bed hydrogenation device filled with a fluidized bed hydrogenation catalyst, and carrying out hydrofining treatment and hydrocracking treatment on the obtained fluidized bed hydrogenation product and the dephenolized oil in a fixed bed hydrogenation system so as to realize clean production of the whole fraction of the coal tar. Wherein the fluidized bed hydrogenation catalyst comprises a metal active component and a carrier for loading the metal active component, and the carrier is prepared by mixing and roasting basalt fiber chopped yarns, natural sponge powder and aluminum hydroxide dry glue powder. According to the processing method of the coal tar full fraction, the coal tar full fraction is converted into a clean fuel product with a high additional value, and the utilization rate of coal tar resources is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of preparing clean fuel from the whole fraction of coal tar, in particular to a method for producing clean fuel from the whole fraction of coal tar, a fluidized bed hydrogenation catalyst suitable for treating the whole fraction of coal tar containing polycyclic aromatic components and a preparation method thereof. Background technology [0002] The world's oil resources show the trend of emphasizing quality and inferior quality; On the other hand, the increasingly stringent environmental protection regulations have changed the global demand for oil products, and the demand for vehicle clean fuel oil and chemical light oil has increased year by year. Therefore, the conversion of inferior heavy oil into clean oil is becoming the main direction of the development of oil refining technology in the world. [0003] In terms of industrial application, fluidized bed hydrogenation is a residue hydrogenation technology wi...
