Problems solved by technology

At present, countries such as Switzerland, Canada and the United Kingdom are actively engaged in research in this area. Switzerland has developed two generations of experimental hydrogen-fueled vehicles. The driving test shows that it is technically feasible for the hydrogen storage system to be used as vehicle fuel, but it is also There are serious problems such as high dehydrogenation temperature, low dehydrogenation conversion rate and easy deactivation of catalyst under non-hydrogenation and non-steady state operation

Embodiment 1

[0055] Immerse SBA-15, SBA-16, MCM-41, MCM-22, MCM-49, SAPO-11, SAPO-41 containing rare earth metals (in the framework) respectively in chloroplatinic acid containing active metals (pH value should be controlled In 3, the platinum content is 3.0%), after soaking for 12 hours, leach out, and after drying at 100°C for 6 hours, put it into a round bottom flask and feed nitrogen gas, and add metered KBH drop by drop 4 -KOH solution reduction, until no more gas is released in the system, and then washed repeatedly with distilled water, then stored in absolute ethanol. The XRD pattern of the catalyst supported by SBA-15 is as follows figure 1 shown.

Embodiment 2

[0057] Immerse SBA-15, SBA-16, MCM-41, MCM-22, MCM-49, SAPO-11, SAPO-41 containing rare earth metals (in the framework) into the active metal palladium chloride or nitrate aqueous solution (pH value should be controlled between 4, palladium content 3.0%), leach after soaking for 12 hours, after drying at 120°C for 3 hours, put into a round bottom flask and feed nitrogen, add metered KBH drop by drop 4 -KOH solution reduction, until no more gas is released in the system, and then washed repeatedly with distilled water, then stored in absolute ethanol. The XRD pattern of the catalyst supported by SAPO-41 is as follows figure 2 shown.

Embodiment 3

[0059] The SBA-15, SBA-16, MCM-41, MCM-22, MCM-49, SAPO-11, SAPO-41 containing rare earth metals (in the framework) were respectively immersed in the aqueous solution containing the active metal ruthenium chloride (pH It should be controlled at 3, the ruthenium content is 3.0%), soaked for 12 hours, drained, dried at 110°C for 4 hours, put into a round bottom flask and fed with nitrogen, and added the measured KBH dropwise 4 -KOH solution reduction, until no more gas is released in the system, and then washed repeatedly with distilled water, then stored in absolute ethanol. The XRD pattern of the catalyst supported by SAPO-11 is as follows image 3 shown.

Abstract

The invention relates to a catalyst for storing hydrogen by an organic matter carrier and a preparation method of the catalyst. The catalyst comprises the following components in percent by weight: 0.15-5 percent of metal active component, 0.1-4 percent of additive, 2-5 percent of adhesive and the balance of carrier. The carrier containing a rare earth metal is prepared by adopting a hydrothermal reaction and then immersed in an active metal water solution, then dried and roasted, and then mixed with the adhesive to obtain the catalyst. Compared with the prior art, the catalyst has the characteristics of proper acid strength, high reaction activity, good selectivity and the like; and the rare earth metal is added, the dispersion degree of the active metal can be increased, surface carbon deposit of the catalyst is reduced, thus the service life of the catalyst is prolonged.

Description

technical field [0001] The invention relates to a dehydrogenation catalyst for petroleum hydrocarbon products and a preparation method thereof, in particular to a catalyst for hydrogen storage on an organic carrier and a preparation method thereof. Background technique [0002] Hydrogen energy is an important energy source for development in the world today. It may replace the existing energy materials gasoline and diesel, and will play a very important role in various fields. Because hydrogen is flammable, easy to diffuse and light in weight, people should give priority to the safety, efficiency and no loss of leakage in the storage and transportation of hydrogen in practical applications. [0003] In 1975, O.S ultan and M.S haw first proposed the concept of using recyclable liquid chemical hydrogen carrier to store hydrogen. This technology realizes hydrogenation and dehydrogenation by means of a pair of reversible reactions between hydrogen storage agents such as certain...
