Fabricating method of displaying base plate, displaying base plate and displaying device

The present invention relates to a palladium-based supported hydrogenation catalyst and a preparation method and application thereof. The catalyst is prepared by the following method: impregnating an AlO-containing carrier with an organic solution containing a bipyridine derivative having hydroxy group, optionally drying followed by impregnating with a mixed solution containing the main active component palladium ions and the auxiliary active component Mions, where M is one selected from Ag, Au, Ni, Pb and Cu; and then optionally drying, and calcining to obtain the catalyst. The preparation method provided by the present invention allows Pd atoms and M atoms to be highly uniformly dispersed on the carrier, which overcomes the adverse impact of the surface tension of the impregnation solution and the solvation effect on the dispersibility of active components. The palladium-based supported hydrogenation catalyst provided by the present invention has excellent hydrogenation activity, ethylene selectivity and anti-coking performance, and can be used in a selective hydrogenation process of C2 fraction.

Palladium-based supported hydrogenation catalyst, and preparation method and application thereof

A selective nickel-based hydrogenation catalyst and the preparation thereof, characterized in that: provided that the catalyst is weighed 100%, it comprises nickel oxide 14-20% as active component, lanthanum oxide and/or cerium oxide 2-8%, and VIB element oxide 1-8% as aids, 2-8% silica, 1-8% alkaline earth metal oxides, and alumina as the balance. The catalyst specific surface area is 60-150 m/g, and the pore volume is 0.4-0.6 ml/g. The catalyst has good hydrogenation performance, especially impurity and colloid resistance and hydrogenation stability. The catalyst can be applied to the diolefin selective hydrogenation of medium or low-distillate oil, especially of the full-distillates pyrolysis gasoline.

Selective nickel based hydrogenation catalyst and the preparation thereof

A selective hydrogenation catalyst, with alumina as carrier, and palladium as active component that distributed on the surface of the carrier in an egg-shell form, characterized in that: provided that the catalyst is weighed 100%, it comprises 0.2-0.5 wt % active component Pd, 2-8 wt % aids lanthanum and/or cerium, and 2-8 wt % alkaline earth metal. The specific surface area of the catalyst is 70-150 m2/g, the pore volume is 0.3-0.6 ml/g, and the crystal form of the carrier may be &#x3b8; form or &#x3b8;, &#x3b1; mixed form mainly composed of &#x3b8; form. The catalyst is suitable for the selective hydrogenation of medium or low distillate oil, especially for the first stage selective hydrogenation of pyrolysis gasoline. The catalyst has good hydrogenation performance, and can keep good hydrogenation activity and stability especially under the condition that the feed contains a small quantity of water, and the content of colloid, arsenic, and diolefin is higher.
