Description
The present invention relates to a kind of method that hydrocarbon raw material is transformed.
US-A-4,390, described a kind of method that hydrocarbon raw material is upgrade in 413, this method is hydrocarbon raw material to be lower than under the condition of the pressure of 14 crust, 260～427 ℃ temperature and the space velocity of 0.1～15 1/lh contact with the catalyzer that contains ZSM-5 in fixed-bed reactor.The content of nitrogenous compound is converted into nitrogen and must be less than 5ppmw in the raw material.Though illustrational raw material is a gas oil, the raw material that is suitable for comprises that also boiling range is 82～649 ℃ a hydrocarbon.Product comprises alkene such as propylene and butylene.It is desirable making alkene like this, because the valuable often product of the alkene of gained.The shortcoming of this method is that raw material must be through strict denitrogenation.This is necessary, because nitrogenously in the raw material many can make rapid catalyst deactivation.
Surprisingly, under the requirement to the nitrogen content of raw material is not so strict condition, use certain zeolite catalyst, make raw material at high temperature carry out contacting of short period of time, can obtain the alkene of high yield with catalyzer.
Therefore, the invention provides the method that a kind of hydrocarbon raw material that makes full boiling point be at most 330 ℃ transforms, this method is included in and makes this hydrocarbon raw material under the temperature that is higher than 500 ℃ is that the zeolite catalyst of the zeolite of 0.3～0.7 millimicron (being preferably 0.5～0.7 millimicron) contacts with a kind of aperture of containing, and is less than 10 seconds duration of contact.Be preferably 0.1 second minimum duration of contact.Be to obtain good result under 0.2～6 second the situation in duration of contact.
Wonderful characteristics of the present invention can be by US-A-4, and 100,218 obtain further instruction, this patent specification describe a kind of use the aperture less than 0.7 millimicron zeolite catalyst by olefin production LPG(liquefied petroleum gas (LPG), C
3 4Stable hydrocarbon) and the method for gasoline.As everyone knows, this zeolite catalyst has that to make conversion of olefines be the catalytic activity of stable hydrocarbon and aromatic hydrocarbon, thus present method to make alkene and generate less gaseous saturated hydrocarbon product be wonderful.
Temperature of reaction is 500～900 ℃, is preferably 550～800 ℃.
The aperture that this zeolite catalyst can contain one or more is 0.3～0.7 millimicron a zeolite.This catalyzer also should contain a kind of refractory oxide as tackiness agent.The refractory oxide that is fit to has aluminum oxide, silicon-dioxide, sial, magnesium oxide, titanium dioxide, zirconium white and composition thereof, is good with aluminum oxide especially.The weight ratio of refractory oxide and zeolite is preferably (10: 90)～(90: 10) and is preferably (50: 50)～(85: 15).The contained zeolite of this zeolite catalyst preferably basically just the aperture be 0.3～0.7 millimicron zeolite.Be to use down at 500～750 ℃ to contain the zeolite catalyst that the aperture is 0.5～0.7 millimicron a zeolite in of the present invention giving an example.
This term of zeolite used in this specification sheets not only includes only crystalline aluminosilicate.It also comprises crystalline silica (silicite), aluminosilicophosphate (SAPO), silicic acid chromium, silicic acid gallium, ferric metasilicate, aluminum phosphate (ALPO), titanoaluminosilicatmolecular (TASO), borosilicate, titanium aluminate or phosphate (TAPO) and iron aluminosilicate.Can be used for method of the present invention and the aperture be that the example of 0.3～0.7 millimicron zeolite has US-A-4,440, SAPO-4 described in 871 and SAPO-4 and SAPO-11, US-A-4,310, ALPO-11 described in 440, US-A-4,500, TAPO-11 described in 651, EP-A-229, the TASO-45 described in 295, for example US-A-4,254, borosilicate described in 297, pure aluminium silicate such as erionite, ferrierite, Q(fhefa) zeolite and ZSM-5, the ZSM type zeolite of ZSM-11, ZSM-12, ZSM-35, ZSM-23 and ZSM-38 and so on.Preferably zeolite system is selected from metal silicate with ZSM-5 structure, ferrierite, erionite and composition thereof.The crystal metal silicate with ZSM-5 structure that is suitable for is just like GB-B-2, the pure aluminium silicate described in 110,559, silicic acid gallium, ferric metasilicate, scandium silicate, silicic acid rhodium and (or) silicic acid chromium.
The alkalimetal oxide that in preparing resulting zeolite, contains a great deal of usually.The most handy technical known method such as ion exchange method are removed these basic metal, then also can calcine, to make the zeolite that is with hydrogen bonding state (in ifs hydrogen form).The zeolite that is used for present method preferably is and hydrogen bonded state basically.
The pressure that present method adopted can change within a large range.But preferably this pressure can make raw material be in gas phase state basically or be gas phase state by contacting with catalyzer under main temperature.Be convenient to reach the duration of contact of the weak point of expectation like that.Therefore, present method should adopt lower pressure.This is favourable, because so just do not need to use expensive compressor and high pressure vessel and other equipment.The pressure range that is fit to is 1～10 crust.Employing is lower than 1 atmospheric pressure and also is fine, but should not do like this.Adopting normal pressure is being favourable on mist.In conversion process, may also have other gaseous substances to exist, as water vapor and (or) nitrogen.
Present method is preferably in the moving-bed and implements.Beds can move up or down.When beds moved up, this method was similar a bit to FCC process.
In present method implementation process, can on catalyzer, form some charcoal Jiao.Therefore, must make catalyst regeneration.The regenerated method is to be preferably in catalyzer to contact back oxidizing gas (as air) processing catalyzer with raw material.Preferably adopt the cyclic regeneration method be similar in the FCC process to be adopted.
If the burnt speed that forms of charcoal is not too fast, can adopt such method, even in the reaction process residence time of granules of catalyst in reaction zone be longer than the residence time of raw material in reaction zone.Certainly, should be less than 10 seconds the duration of contact of raw material and catalyzer.Duration of contact is general consistent with the residence time of raw material.The residence time of catalyzer is preferably 1～20 times of the residence time of raw material.
Though the requirement to the weight ratio of catalyzer and raw material is not strict, per 1 kilogram of raw material should use the catalyzer more than 1～150 or 150 kilogram.The weight ratio of catalyzer and raw material is preferably (20～120): 1.
The raw material that present method will transform contains the hydrocarbon that full boiling point is at most 330 ℃.According to these characteristics, low-density oil cut such as raw gasline and kerosene include interior.The initial boiling point of raw material is preferably-45 ℃.The raw material that is fit to comprises C
3-4Hydrocarbon (for example LPG(liquefied petroleum gas (LPG))), raw gasline, gasoline fraction, kerosene(oil)fraction and composition thereof.
With US-A-4,390,413 method is compared, and one of advantage of present method is can use the higher raw material of nitrogen content and can not influence activity of such catalysts basically.The nitrogen content of the raw material that is suitable for change etc. for nitrogen can be greater than 25ppmw.Even can reach 100～1000ppmw.
