Abstract
The invention discloses a cascade reaction process for hydrogenation adsorption desulfurization and hydro-dearomatization. A hydrogenation adsorption catalyst and a hydro-dearomatization catalyst are directly and serially filled, and a raw material is removed with sulfide through the hydrogenation adsorption catalyst under the condition of hydrogenation adsorption, and then is removed with aromatic hydrocarbon through the hydro-dearomatization catalyst under the condition of hydro-dearomatization. The process has the advantages that no hydrogen sulfide is generated in a first reactor, and the content of the sulfide in a product is lower, thereby prolonging the using period of a second hydro-dearomatization catalyst, reducing operation cost, reducing equipment, and saving the investment.
Description
Technical field
The invention belongs to a kind of hydrogenation adsorption desulfurize and hydrogenation aromatics-removing cascade reaction technology.
Background technology
Extracting is used to edible oil 6 along with country
#The raising of solvent oil specification of quality, 6
#Aromaticity content index in the solvent oil is reduced to 0.1%, present industrial production 6 from 1%
#The solvent oil technology reaches this index certain difficulty.Produce 6
#The raw material of solvent oil generally is that aromatic hydrocarbons is raffinated oil, straight-run spirit or field condensate, the solvent that present industrial extracting aromatic hydrocarbons uses is the sulfide tetramethylene sulfone, contain a certain amount of organic sulfide during aromatic hydrocarbons is raffinated oil inevitably, also have organic sulfide to exist in straight-run spirit and the field condensate.Because the hydrogen of hydrogenation generally also contains the inorganic sulfur of 0.5ppm, these sulfide all are the poisonous substances that deep hydrogenation removes the arenes catalytic agent, there are these sulfide to exist the agent of hydrogenation and removing arenes catalytic can not keep stable aromatic hydrogenation activity, remove 6 by shortening
#Aromatic hydrocarbons in the solvent oil becomes a difficult problem.Traditional Hydrobon catalyst is such as Ni-Mo (W)/Al
2O

2O
3Be that organosulfur hydrogenation in the raw material is produced hydrogen sulfide, the product behind the hydrogenation is cooled to liquid and passes through stripper plant again the hydrogen sulfide stripping that produces.Also contain a large amount of gas vulcanization hydrogen in the hydrogen that recycles, also need to carry out adsorbing and removing hydrogen sulfide.And the hydrogen sulfide in the product might be further generates mercaptan with olefine reaction, and the product organic sulfur content behind the hydrogenation is difficult to be lower than 0.5ppm.Because these remove the existence of hydrogen sulfide device, desulphurization reactor can not directly be connected with taking off the aromatic hydrocarbons reactor, enter two sections remove the aromatic hydrocarbons reactor before raw material and hydrogen need reheat, wasted a large amount of energy.
Ni/ZnO is a good sulfide hydrogenation adsorptive catalyst, its catalysis absorption principle is, by the Ni on the catalyzer sulfide is carried out hydrogenation and destroy its structure, sulphur atom in the sulfide is transferred on the support of the catalyst ZnO, there is not hydrogen sulfide to generate so add the product of hydrogen adsorption through Ni/ZnO, sulphur content can be lower than 0.03ppm in the product, and the elementary sulfur loading capacity can reach more than 20% of catalyst body quality.Also just need not traditional Ni-Mo (W)/Al

2The hydrogenation and removing aromatic hydrocarbons activity of last catalyzer is very high, can make the aromaticity content in the raw material be lower than 0.1% by shortening under appropriate reaction conditions.If reaction raw materials contains 0.5ppm sulfide, above-mentioned catalyzer will reduce so that inactivation, and the speed of catalyst activity reduction or inactivation is relevant with the sulphur content in the raw material.The high inactivation of sulphur content is just fast, and the low inactivation of sulphur content is just slow.In a word, the sulphur content in the raw material is the main poisonous substance of Ni, Pt, Pd or the agent of Pt-Pd hydrogenation and removing arenes catalytic, and a certain amount of sulfide is arranged in the raw material, and above-mentioned catalyzer just can not keep aromatic hydrogenation activity steadily in the long term.In order to make the agent of hydrogenation and removing arenes catalytic that long life-span be arranged, must at first reduce the sulphur content in the raw material as far as possible and could realize this target.
Summary of the invention
The object of the invention provides a kind of hydrogenation adsorption desulfurize and hydrogenation aromatics-removing cascade reaction technology of hydrogenation and removing arenes catalytic agent long service life.
Technology of the present invention is to adopt hydrogenation adsorptive catalyst and the agent of the hydrogenation and removing arenes catalytic filling of directly connecting, raw material removes sulfide by the hydrogenation adsorptive catalyst earlier under the hydrogenation adsorption conditions after, agent removes aromatic hydrocarbons under hydrogenation and removing aromatic hydrocarbons condition through the hydrogenation and removing arenes catalytic again.
Petrol and diesel oil cuts such as aforesaid raw material can be petroleum naphtha, raffinate oil, field condensate.
Aforesaid hydrogenation adsorptive catalyst is Ni/ZnO.
The hydrogenation adsorption conditions of aforesaid hydrogenation adsorptive catalyst is: at 270-330 ℃, 1.3-2.5MPa, 1.0-3.5h

The present invention is a cascade reaction technology, and filling Ni/ZnO hydrogenation adsorptive catalyst in first reactor for the sulfide hydrocracking in the stock oil, and is adsorbed on elementary sulfur on the catalyst body.Because this process does not produce hydrogen sulfide, just do not need reaction product is cooled to liquid, do not need reaction product and Hydrogen Separation yet, the product of first reactor directly can be added the reaction of carrying out hydrogenation and removing aromatic hydrocarbons in second reactor.What load in second reactor is that Ni, Pt, Pd or Pt-Pd load on Al

2Aromatic hydrocarbon hydrogenation catalyst, these catalyzer all have very high hydrogenation and removing aromatic hydrocarbons ability, if but the ability that contains sulfide catalyst hydrogenation and removing aromatic hydrocarbons in the raw material is very fast forfeiture, it is closely related to we can say that these catalyst hydrogenations remove the activity and the sulfide content in the raw material of aromatic hydrocarbons.High more through the sulfide content in the catalyzer raw material, it is short more that catalyst hydrogenation removes the work-ing life of aromatic hydrocarbons.Ni/ZnO hydrogenation adsorptive catalyst can make that sulfide content is lower than 0.03ppm in the product, is more conducive to the agent of hydrogenation and removing arenes catalytic and keeps active for a long time.If use traditional Ni-Mo (W)/Al

3Hydrobon catalyst, sulfide in the raw material produces hydrogen sulfide through catalyst hydrogenation, product need be cooled to liquid and pass through gas-liquid separation again, and hydrogen and product will remove respectively to reheat behind the hydrogen sulfide and just can enter second reactor and carry out the reaction of hydrogenation and removing aromatic hydrocarbons.Because this process produces a large amount of hydrogen sulfide, hydrogen sulfide can generate mercaptan with the olefine reaction in the product, and the content of sulfide is difficult to be lower than 0.5ppm in this process liquid product.With use Ni/ZnO hydrogenation adsorptive catalyst to remove sulfide to compare, the sulfide that not only enters in the hydrogenation and removing aromatic hydrocarbons reactor has increased more than 10 times, but also has increased refrigerated separation equipment and hydrogen sulfide stripping equipment, operates also loaded down with trivial detailsly, has wasted the energy.
The advantage of method that the present invention narrates is not produce in first reactor hydrogen sulfide, and sulfide content is lower in the product, played the life cycle that has prolonged the agent of second hydrogenation and removing arenes catalytic, reduced running cost, guaranteed steadily carrying out of hydrogenation reaction, avoided the energy of waste because cooling is heated.And the equipment that reduces, saved investment.
