The pressure in the reaction process is 1-4 MPa, the temperature is 250-350 ℃, and the liquid phase space velocity is 1-10 h-1The volume ratio of hydrogen to oil is 100-500.
Description
The present invention relates to the method and the Preparation of catalysts method of a kind of pressure gasoline (petroleum naphtha) selective hydrodesulfurization, it is to belong in the petroleum chemical industry the improvement and the innovation of light-end products process for refining, exactly is the selective hydrogenation desulfurization process of pressure gasoline in the presence of catalyzer (petroleum naphtha).
As everyone knows, pressure gasoline (petroleum naphtha), particularly catalytically cracked gasoline (petroleum naphtha) or heavy oil fluid catalytic cracking gasoline (petroleum naphtha) contain a large amount of sulphur.The method that reduces sulphur content has: 1) to cracking or the unitary full feedstock hydrofining of coking, 2) to these unitary hydrogenation of net product.First kind of selection is because need huge hydrotreater and consume a large amount of hydrogen, and be costly.Second kind of selection is shortcut but can causes alkene (account for the 20~80v%) saturated of raw material usually, this octane value ((RON+MON)/2) that also can reduce gasoline products reaches 10-20 unit simultaneously.The loss of octane number relevant with desulfurization is a very big impact to the octane value of refinery's gasoline product.The typical technology of previously disclosed relevant pressure gasoline (petroleum naphtha) hydrogenating desulfurization comprises:
1. U.S.Pat.No.4,140,626 (Bertolacini and Sue-A-Quan) have described a kind of selective hydrodesulfurization technology, are supported on the supported catalyst that is accounted for 70wt% by MgO at least with the metal of group vib and VIII family.More particularly, the group vib metal is Mo, and VIII family metal is Co.Catalyzer contains the CoO of 3wt% and the MoO of about 16wt%
3Be supported on the pure MgO carrier.In the hydrogenating desulfurization rate is 75~85%, degree of olefin saturation quite low (≤40wt%), the loss of octane value less (≤2 units).
2. U.S.Pat.No.4,132,632 (Yu and Myers) account for 4~6wt% except metal load is restricted to the group vib metal, and VIII family metal accounts for outside 0.5~2wt%, other very similar above-mentioned patent.And more particularly adopt group vib metal M o and VIII family metal Co.Catalyst I contains the CoO of about 1wt% and the MoO of about 5wt%
3, be supported on the pure MgO carrier.Catalyst I I contains the CoO of about 3wt% and the MoO of about 17wt%
3Carrier comprises the MgO of 80wt% (as above-mentioned U.S.Pat.No.4,140,6626 catalyzer). catalyst I is poorer than the hydrodesulfurization performance of catalyst I I usually, but catalyst I (is about 82~84%) on identical hydrogenating desulfurization level obtains lower degree of olefin saturation and higher octane value than catalyst I I, loss of octane number very little (being about 1.6 units).In addition, for two kinds of catalyzer, research the hydrogenating desulfurization scope in, degree of olefin saturation quite low (≤40wt%), the loss of octane value less (≤2.6 units).
3. (San Antonio in the 1978NPRA meeting, Texas), Coates, Myers and Sue-A-Quan have delivered the paper that is entitled as " the pressure naphtha hydrogenating desulfurization of minimal octane value loss ", have illustrated the bright prospect that Amoco is referred to as " selectivity superrefining technology ".This paper is delivered about above-mentioned patent issue the previous year.This paper is mentioned two kinds of catalyzer (probably deriving from above-mentioned two patents), and wherein selective desulfurization is the technical characterictic of this technology.Raw catalyst shows low inactivation rate than conventional hydrotreating catalyst aspect hydrogenating desulfurization.The hydrogenating desulfurization rate is that the loss value of 90% o'clock octane value be it is said 4 MON or 4.5 RON.The loss of octane number of mentioning in the document is more much higher than Amoco later patents.
4. GB2,225,731 issued contain VIB, VIII family metal hydrogenation composition homogeneous phase is supported on and contains MgO and Al
2O
3Hydrotreating catalyst on the carrier.The Mg/Al mol ratio is 3~10/1.It is said, this catalyzer be supported on Al
2O
3On similar catalyzer suitable hydrodesulfurization activity is arranged.
