In view of this, the invention is particularly proposed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
In a first aspect, embodiments of the present invention provide a liquid catalyst for catalytic cracking of hydrocarbons, the liquid catalyst being composed of a first component and a second component, wherein the first component is selected from elemental metals or alloys, and the second component is selected from metal carbides.
Chemical bonds in hydrocarbons comprise carbon-carbon bonds and carbon-hydrogen bonds, and the breaking of the two chemical bonds to crack the hydrocarbons requires large energy. There are two methods for preparing carbon and hydrogen by traditional hydrocarbon cracking, namely direct thermal cracking and catalytic cracking. The direct thermal cracking reaction of hydrocarbons has high temperature, the product is mainly carbon black, the energy consumption is large, the economic benefit is poor, and the application of the route is limited. The hydrocarbon catalytic cracking mainly adopts a solid catalyst with dehydrogenation function, and the catalyst is quickly deposited with carbon, so that hydrocarbon cracking reaction and catalytic decarburization switching are required, the operation is complex, the equipment requirement is high, and the economical efficiency is poor. It can be seen that the catalysts currently used for the catalytic cracking of hydrocarbons all have the following problems: under the harsh environment of high temperature, etc., the dehydrogenation and carbonization occur, so that the surface of the catalyst is rapidly deposited with carbon and inactivated, and the catalyst is frequently regenerated.
In view of the above, the inventors have long practiced to provide a liquid catalyst for cracking hydrocarbons, the liquid catalyst being composed of a first component and a second component, the first component being selected from elemental metals or alloys, and the second component being selected from metal carbides. Catalytic cracking of hydrocarbons can be achieved with the liquid catalyst for reasons which may be:
the properties of the metal carbide in the second component are similar to those of the VIII group noble metal, and the metal carbide has excellent dehydrogenation function. The hydrocarbon bubbles generate catalytic dehydrogenation reaction in the liquid catalyst, and hydrogen obtained by cracking rises to the surface of the liquid catalyst in the bubbles and is automatically separated from the liquid catalyst; one part of carbon obtained by hydrocarbon cracking is condensed on the wall of the bubble catalyst to generate carbon, and the other part of carbon enters the liquid catalyst; the carbon that enters the liquid catalyst partially combines with the metal to form new metal carbides, and partially becomes free carbon. Decomposing the metal carbide in the liquid catalyst to obtain metal and free carbon; the free carbon in the catalyst is supersaturated, and is precipitated on the surface of the catalyst to form new carbon which floats on the surface of the catalyst. The hydrocarbon bubbles continuously contact with the real-time atomically updated metal carbide in the rising process, so the reaction rate is faster than that of a solid catalyst; the liquid catalyst provided by the embodiment of the invention is in a liquid state, and the mass transfer rate of carbon atoms is higher than that of a solid catalyst, so that the reaction rate can be further improved.
Therefore, in the process of catalyzing hydrocarbons by using the liquid catalyst provided by the embodiment of the invention, the catalyst is in a liquid state, the first component and the second component both have good dehydrogenation performance, and the liquid catalyst can also increase the renewal speed of metal and metal carbide on the surface of bubbles, thereby greatly improving the reaction rate and capacity.
In an optional embodiment, in the liquid catalyst, the mass percentage of the first component is 0 to 99.9%, and the mass percentage of the second component is 0.1 to 20%.
In alternative embodiments, the metal in the first component is selected from the group consisting of non-radioactive metals;
preferably, the constituent elements in the first component include the metal elements in the second component.
In an alternative embodiment, the first component has a melting point of not higher than 1200 ℃ and a boiling point of not lower than 2000 ℃.
In an alternative embodiment, the first component comprises at least one non-radioactive metal element selected from the group consisting of IA, IIA, IIIB, IVB, VB, VIB, VIIB, VIIIB, IB, IIB, IIIA, IVA, VA, VIA and VIIA.
In an alternative embodiment, when the first component contains an alkali metal or an alkaline earth metal, the first component is composed of two or more metal elements, at least one of which is a non-alkali metal and a non-alkaline earth metal;
preferably, the mass percentage of the alkali metal or alkaline earth metal is not higher than 10%.
As a preferable embodiment in the examples of the present invention, when the first component contains an alkali metal or an alkaline earth metal, the first component is composed of two or more metal elements, at least one of which is a non-alkali metal and a non-alkaline earth metal. This is due to: the alkali metal and the alkaline earth metal have low melting points, more active chemical properties and higher dangerousness, and other metals are added into the alkali metal and the alkaline earth metal to form an alloy, so that the chemical properties are reduced, and the safety of a catalytic cracking process is improved.
In an alternative embodiment, the second component is selected from carbides of non-radioactive metals.
In an alternative embodiment, the second component comprises one or more of Fe, Ti, Gr, Co, Ni, V, Zr, Ca, Mo, Mn and W metal carbides formed with carbon.
In a second aspect, the embodiments of the present invention also provide the application of the above-mentioned liquid catalyst in the preparation of carbon and hydrogen by catalytic cracking of hydrocarbons.
In the embodiment of the invention, the liquid catalyst is applied to cracking of hydrocarbons, particularly cracking of hydrocarbons, carbon-carbon bonds and carbon-hydrogen bonds in the hydrocarbons can be broken by using the liquid catalyst, and the final product only contains gaseous H2And solid carbon, and a product with high purity can be easily obtained by simple gas-solid-liquid separation. The gaseous product has a high hydrogen content and is easily purified, so that the hydrocarbons are used as high-quality carbon and H2The source of the raw material is ideal. The temperature of the whole reaction system is uniform, the reaction activity of the liquid catalyst is high, and carbon and H are generated by reaction2Liquid catalyst, H2And carbon is easily separated, specifically:
the hydrocarbon is introduced into the liquid catalyst, the liquid catalyst can be used as a heat carrier for catalytic cracking of the hydrocarbon at the same time, the hydrocarbon is subjected to catalytic dehydrogenation reaction under the action of the liquid catalyst to generate carbon and hydrogen, the hydrogen is discharged from a gas outlet of the reactor, the generated carbon floats on the liquid catalyst and is easily separated without affecting the performance of the liquid catalyst, namely, the liquid catalyst can always exert the catalytic activity of the catalyst without inactivation, so that the catalytic efficiency of the catalyst is greatly improved, and the hydrocarbon has very high conversion rate.
