Description
Technical field
The present invention relates to chemical catalysts, and in particular to the ruthenium-based catalytic agent carrier of the Hydrophilic modification of partial hydrogenation of benzene,
The preparation method and application of carrier modification method and catalyst.
Background technique
Cyclohexene in partial hydrogenation of benzene product is a kind of important organic intermediate, due to its with active double bond and
It is widely used in the production of medicine, pesticide, agricultural chemicals, feed addictive, polyester and other fine chemical products, especially
It is that there is huge economic value and wide in the Fypros high value added product synthesis technology such as nylon 6, nylon66 fiber
Market prospects.Unique byproduct hexamethylene of partial hydrogenation of benzene, through oxidation, cyclohexanone oxamidinating, cyclohexanone oxime Beckmann rearrangement
Etc. processes caprolactam and adipic acid (raw materials of the Fypros such as nylon 6 and nylon66 fiber) can be obtained, which is current work
The main stream approach of caprolactam and adipic acid is produced in industry, that there are process flows is tediously long, energy and material consumption is big, yield is low, environment is dirty
The disadvantages of dye.
The new process tool that cyclohexene, cyclohexene oxide or hydration prepare caprolactam and cyclohexanol is prepared through partial hydrogenation of benzene
Have the advantages that process is short, atom utilization is high, environmental-friendly, safe and efficient.The method of traditional mode of production cyclohexene includes cyclohexanol
That all there is process flows is complicated for dehydration, cyclohexane halide dehydrohalogenation, cyclohexane dehydrogenation etc., energy consumption is high, yield is low, at high cost
The disadvantages of, it is unable to satisfy the demand for development of modern compound probability.1963, with ruthenium black catalyst first passage partial hydrogenation of benzene system
It obtains cyclohexene (J.Catal., 1963,2,79), is caused since then by the new process that partial hydrogenation of benzene prepares cyclohexene both domestic and external
Extensive concern and research.1989, partial hydrogenation of benzene was prepared cyclohexene applied to industrial production first by Japanese Asahi Kasei Corporation.

Agent is broadly divided into non-loading type and two kinds of support type, using noble ruthenium as active component, also by the precipitation method, infusion process and chemistry
The preparation of the methods of former method.In the product of benzene hydrogenation, the thermodynamic stability of the hexamethylene (mark of hexamethylene more much higher than cyclohexene
It is -153.4 kJ/mol that standard, which generates heat, and cyclohexene is -63.9 kJ/mol), so benzene hydrogenation process is difficult to rest on intermediate production
The object cyclohexene stage.How effectively to promote the cyclohexene generated to be desorbed in time from catalyst surface and comes out and inhibit cyclohexene
Absorption becomes where the key technology of the technique.In order to improve the selectivity of cyclohexene in partial hydrogenation of benzene reaction, industrial production
In experimental study, by using one by water phase, oily phase (benzene, cyclohexene and hexamethylene), gas phase (hydrogen) and solid phase (catalysis
Agent) composition four phase reaction systems, design hydrophilic catalyst, allow catalyst surface to form stable aquitard, using anti-
Under the conditions of answering cyclohexene in water solubility be much smaller than benzene the characteristics of, the moisture film of catalyst surface can effectively promote product hexamethylene
The desorption of alkene simultaneously inhibits its absorption, and then improves the selectivity of cyclohexene.Therefore, the core of high cyclohexene selectivity is to design
Hydrophilic catalyst system.Current research work is based primarily upon the expansion of ruthenium-based catalyst system, surrounds hydrophilic catalyst
The selection of carrier, the influence of auxiliary agent, the influence of carrier cellular structure, the side such as influence of organic or inorganic additive in reaction system
Face has carried out a large amount of exploration.
