Description

A kind of Hydrobon catalyst
Technical field
The present invention relates to catalyst technical field, be specifically related to a kind of hydrodesulfurization catalyst for refining, more preferably relate to one Plant FCC gasoline hydrodesulfurization and reduce the catalyst of octane number reduction amplitude.
Background technology
Entering 21st century, demand and the use of fuel oil increase substantially, and sulfur-containing compound therein is brought Problem of environmental pollution, more cause the concern of people.The oxysulfide that sulfide in fuel oil produces through engine combustion (SOx) be discharged in air, produce acid rain and fumes of sulphuric acid type pollution etc., cause atmospheric pollution.
Sulfur is a kind of harmful substance that nature is present in gasoline, and in gasoline product, the sulfur of more than 80% carrys out self-catalysis and splits Changing (FCC) gasoline, along with constantly becoming of crude oil is heavy, the sulfur content in FCC gasoline also can be continuously increased.External gasoline is generally from FCC (34%), catalytic reforming (33%), and the technique such as alkylation, isomerization and etherificate (the most totally 33%)；And home-produced fuel 80% is from FCC gasoline.Due in gasoline the sulfur of 85%～95% from FCC gasoline so that the sulfur content in China's gasoline More than external gasoline a lot.A lot of experts have carried out the research that motor vehicle exhaust emission is affected by sulfur, and result shows: if by gasoline In sulfur content from 450 μ g g-1It is reduced to 50 μ g g-1, NO in vehicle exhaustxAverage minimizing 9%, CO averagely reduces 19%, HC averagely reduce 18%, and Toxic averagely reduces 16%.Thus, effective fuel oil hydrodesulfurization technology, to society, warp Ji, the development of environment have important effect.
Most effective, the most economical sulfur method that hydrodesulfurization (HDS) technology is well recognized as at present, especially selective hydrogenation Desulfurization technology, i.e. suppresses the saturated to reduce loss of octane number of alkene while the removing a large amount of sulfur-containing compound of gasoline as far as possible. The features such as this kind of technology has operating condition and relaxes, and yield of gasoline is high, and hydrogen consumption is low and loss of octane number is little.Hydrodesulfurization technology It is crucial that the selection of Hydrobon catalyst, the cobaltmolybdate catalyst of support type is the gasoline hydrodesulfurizationcatalyst catalyst that a class is important, It is typically cobalt molybdenum to load on porous support (such as aluminium oxide, silicon oxide, activated carbon or its complex carrier), is widely used in adding In hydrogen sweetening process, to obtain premium-type gasoline product.
Hydrodesulfurization (HDS) technology is to grow up the fifties, and the nineties, this technology welcome second improving and developing Individual peak period, its technical maturity, all the time, become sulfur, nitrogen, oxygen in removing distillate, improve oil product Practical Performance with clear The maximally efficient means of cleanliness.The activity and selectivity of catalyst is the key factor affecting hydrofinishing efficiency and the degree of depth, Economy and environmental benefit that high performance catalyst is brought are very significant, have therefore attracted numerous enterprises and researcher to put into In developing to efficient catalyst, the catalyst prod develop many function admirables, differing from one another.Hydrogenation technique is sent out rapidly The basic reason of exhibition is the development of catalyst, but alkene can be caused while routine techniques desulfurization saturated and product octane number (RON) decline, therefore desulfurization and the few selective hydrogenation new technique of loss of octane number can become what HDS method in recent years was improved Main way.
The RESOLVE technological development of Akzo Nobel company exploitation catalytic cracking reduces the RESOLVE of content of sulfur in gasoline Additive product series, uses high hydrogen transfer activity component and ADM-20, and cracking gasoline sulfur content can be made to reduce by 20%, RESOLVE-700 gasoline reduces in sulfur additives currently industrial evaluation.
Exxon research engineering company is Containing Sulfur in selectively removing FCC gasoline with Akzo Nobel company joint development The Scanfining technology of compound, and pushed this technology to industrialization in 1998.It uses traditional hydrotreating flow process, logical Cross meticulous selecting catalyst (RT-225), make loss of octane number and hydrogen consumption reach minimum.
The Prime-G technology of France's IFP exploitation, this technology, by France studying and designing institute (IFP) exploitation, uses dual catalyst System.Its process conditions relax, and hydrogenation of olefins activity is low, does not occur alkene saturated and cracking reaction, and liquid yield reaches 100%, Desulfurization degree is more than 95%, and loss of octane number is few, and hydrogen consumption is low.By FCC heavy petrol hydrodesulfurization, being in harmonious proportion the gasoline product obtained can To realize the target of sulfur content 100～150 μ g g-1；By the hydrodesulfurization respectively of FCC petroleum benzin, sulfur content 30 μ can be realized The target of g g-1.
For the feature of domestic FCC gasoline sulfur-bearing, Fushun Petrochemical Research Institute (FRIPP) develops FCC gasoline and selects Property hydrogen addition technology (OCT-M) and full distillation gasoline selective hydrogenation technology (FRS), device can produce sulfur nutrient and be not more than 150μg·g-1GB III gasoline.OCT-M technology, after Shijiazhuang Oil Refinery, China Petrochemical Corp. continuously runs 17 months, uses Two kinds of prioritization schemes that FRIPP recommends, after FCC gasoline hydrogenation, sulfur nutrient reaches GB III and IV standard.
On May 5th, 2016, the issue of seven departments such as the Committee of Development and Reform, the Ministry of Finance, Chinese Ministry of Environmental Protection " accelerates product oil quality about printing and distributing Upgrade job scheme " notice, scheme clearly expands automobile-used vapour, diesel oil state five standard performs scope.From original Jing-jin-ji region, length three Angle, region, Pearl River Delta key cities expand 11, whole eastern region provinces and cities (Beijing, Tianjin, Hebei, Liaoning, Shanghai, river to Soviet Union, Zhejiang, Fujian, Shandong, Guangdong and Hainan).Before 31 days October in 2015, eastern region is protected possesses manufacturing country five mark for enterprise Quasi-motor petrol (containing ethanol petrol blend component oil), the ability of derv fuel.On January 1st, 2016 rises, and eastern region supplies comprehensively The motor petrol (containing E10 ethanol petrol) of state five standard, derv fuel (containing B5 biodiesel) should be met.
At present, the main method reducing FCC gasoline sulfur content is catalytic desulfurhydrogenation.But hydrotreating method exists such as Lower deficiency: (1) equipment investment is big；(2) severe reaction conditions of the de-thiophenic sulfur of hydrogenation, operating cost is high；(3) alkene is de-at hydrogenation Easily occur saturated under the conditions of sulfur, not only consume a large amount of hydrogen, and cause octane number to reduce.FCC gasoline desulfurization degree requirement The highest, operating condition is the harshest, and the loss of octane number is the biggest.
A kind of Hydrobon catalyst is provided, can effectively the sulfur content in gasoline be controlled at below 10ppm, To meet state five standard, octane number loss simultaneously is less or do not lose, and is a difficult problem facing of this area.
Summary of the invention
It is an object of the invention to propose a kind of Hydrobon catalyst, this catalyst can be by the total sulfur in FCC gasoline Content is reduced to below 10ppm, to meet gasoline state five standard.Meanwhile, the employing of this catalyst also makes the octane of FCC gasoline Value significantly reduces.
For reaching this purpose, the present invention by the following technical solutions:
The catalyst of a kind of hydrodesulfurization, described catalyst includes carrier and active component.
Described carrier is incorporation hetero atom Co in synthetic bone shelf structure2+MCM-41.
Described active component is nitridation two molybdenum MO2N, tungsten nitride W2N, molybdenum carbide Mo2C and the mixture of tungsten carbide wc.
MCM-41 is ordered into mesoporous material, and its duct is that six side's ordered arrangement, size are uniform, aperture size can with synthesis time The difference adding directed agents and synthetic parts changes between 1.5～10nm, lattice parameter about 4.5nm, specific pore volume about 1mL/g, MCM-41 uniform pore diameter, has higher specific surface area (1000m2/ g) and big adsorption capacity (0.7mL/g), the most organic The free diffusing of molecule.The present invention through in numerous mesoporous materials, such as MCM-22, MCM-36, MCM-48, MCM-49, MCM56, carries out contrast test selection, finds that only MCM-41 can reach the goal of the invention of the present invention, and other mesoporous materials are all Having such-and-such defect, there is the technical difficulty being difficult to overcome when being applied in the present invention, therefore the present invention selects to use MCM-41 is as carrier basis.
The acidity of silica MCM-41 own is the most weak, is directly used as catalyst activity relatively low.Therefore, it is changed by the present invention Property, to increase its catalysis activity.The approach that MCM-41 mesopore molecular sieve is modified is by the present invention: in MCM-41 building-up process, Add Co2+Saline solution, before MCM-41 framework of molecular sieve structure is formed, by isomorphous substitution by Co2+Replace part skeleton unit Element thus embed in the skeleton of molecular sieve, improve on the whole MCM-41 mesopore molecular sieve catalysis activity, absorption and heat Mechanical stability can wait.
