preparation example Construction

[0034] The preparation method of a kind of highly active bifunctional catalyst provided by the invention comprises the following steps:

[0035] Synthesize nano zirconia with high specific area first, then load trifluoromethanesulfonic acid on nano zirconia with high specific surface area by impregnation method to prepare nano zirconia carrier with trifluoromethanesulfonic acid, and finally disperse metal Ni in The surface of the trifluoromethanesulfonate nano-zirconia carrier is supported to prepare a highly active bifunctional catalyst.

[0036] Further, the preparation method specifically includes the following steps:

[0037] a. Preparation of nano zirconia with high specific surface area

[0038] a1. Take a certain amount of zirconium n-butoxide with a concentration of (0.15-0.2) mol / L and dissolve it in the organic solution, and stir it magnetically for 10-20 minutes to completely dissolve the zirconium n-butoxide in the organic solvent, and place it in polytetrafluoroe...

Embodiment 1

[0057] 1. Prepare 25 mL of ethanol solution with a zirconium n-butoxide concentration of 0.2 mol / L, stir it magnetically for 10 minutes, and place it in a polytetrafluoroethylene liner A; put the liner A into a polytetrafluoroethylene pre-filled with 10 mL of distilled water In the liner B, wherein, the port A of the polytetrafluoroethylene liner is open, and the port B of the polytetrafluoroethylene liner is closed to form a ring sleeve liner. The hydrothermal synthesis device is as follows: image 3 shown;

[0058] 2. Put the above-mentioned sleeve liner in a hydrothermal reaction kettle, react in a 433K oven for 18 hours, then cool to room temperature, wash with ethanol solution, centrifuge, and dry at 363K for 24 hours to obtain high specific surface area nano oxide Zirconium, its electron microscope picture is as follows figure 2 shown;

[0059] 3. Take 5g of high specific surface area nano-zirconia and 10mL of trifluoromethanesulfonic acid, add them to a 50mL three-ne...

Embodiment 2

[0065] The difference from Example 1 is that the amount of liquid nickel tetracarbonyl is 0.5ml, and the high activity bifunctional catalyst (Ni 6％ -TFMSA / NanoZrO 2 ).

Abstract

The invention provides a high-activity bifunctional catalyst as well as a preparation method and application thereof, and the preparation method comprises the following steps: loading trifluoromethanesulfonic acid on nano zirconium oxide with high specific surface area through an impregnation method to prepare a trifluoromethane sulfonic acid loaded nano zirconium oxide solid; and dispersing metal Ni on the surface of the trifluoromethane sulfonic acid loaded nano zirconium oxide solid to prepare the high-activity bifunctional catalyst. The prepared high-activity bifunctional catalyst is applied to direct liquefaction of low-metamorphic coal to produce clean liquid fuel, under the synergistic effect of super acid and metal Ni, directional cutting and high hydro-conversion of the low-metamorphic coal can be achieved under the mild condition, high-added-value fine chemicals are obtained from the low-metamorphic coal, and high-efficiency and high-value comprehensive utilization of the low-rank coal is realized.

Description

technical field [0001] The invention relates to the technical field of preparation of bifunctional catalysts, in particular to a high-activity bifunctional catalyst, a preparation method and an application thereof. Background technique [0002] The macromolecular structure of organic matter in coal is connected with a large number of condensed aromatic rings through bridge chains, and some aromatic rings also have alkyl side chains and heteroatom-containing groups. Under mild conditions, the bridge chains connecting the aromatic rings in the coal organic matter macromolecules can be cleaved and the heteroatoms outside the aromatic rings can be removed. It is expected to obtain a series of pure organic compounds with high added value through subsequent fine separation. Hydrogenation of aromatic rings in difficult-to-separate soluble organic small molecules to saturated rings and removal of heteroatoms is an important way to obtain high-density liquid fuels mainly composed of...
