Abstract
The present invention relates to desulfurization of hydrocarbon oil field, the method for disclosing a kind of desulfurization of hydrocarbon oil catalyst and preparation method thereof and desulfurization of hydrocarbon oil.On the basis of the gross weight of the desulfurization of hydrocarbon oil catalyst, which contains：1) at least one metal oxide selected from IIB, VB and group vib element of 10~80 weight %；2) the non-aluminum oxide of 3~35 weight %, the non-aluminum oxide are at least one of titanium dioxide, zirconium dioxide and stannic oxide；3) vanadium carbide of 5~40 weight %；4) molecular sieve with FAU and/or BEA structures of 1~20 weight %；5) metallic promoter agent of 5~30 weight %, the metallic promoter agent are selected from least one of cobalt, nickel, iron and manganese.The desulfurization of hydrocarbon oil catalyst has desulphurizing activated, the more preferable abrasion resistance properties of more preferable stability and higher, and service life is longer.
Description
Technical field
The present invention relates to desulfurization of hydrocarbon oil field, and in particular, to a kind of desulfurization of hydrocarbon oil catalyst and preparation method thereof and hydrocarbon
The method of oily desulfurization.
Background technology
As people are to the pay attention to day by day of environmental protection, environmental regulation is also increasingly stringent, and reduces the sulphur of gasoline and diesel oil
Content is considered as one of most important measure for improving air quality.Most of sulphur in China's gasoline products come from hot-working
Gasoline blending component, such as catalytically cracked gasoline.Therefore the reduction of sulfur content helps to reduce the production of China's gasoline in hot-working petroleum
The sulfur content of product.The existing gasoline products standard GB 17930-2011 in China《Motor petrol》It is required that on December 31st, 2013,
Sulfur content must drop to 50 μ g/g in gasoline products.And following gasoline product quality standard will be stringenter.At this
In the case of kind, catalytically cracked gasoline has to pass through the requirement that deep desulfuration can just make gasoline products meet environmental protection.
At present, the process for deep desulphurization of oil product mainly selective two kinds of desulfurization of catalytic desulfurhydrogenation and catalytic hydrogenation absorption
Method.Catalytic hydrogenation absorption desulfurization is to realize under conditions of hydrogen to inhale in the sulfide in hydrocarbon ils in certain temperature, pressure and facing
Attached removing, it is not high which has the characteristics that hydrogen consumes low and to hydrogen purity requirement so that the technology is in terms of fuel desulfuration
Have broad application prospects.
