Description
Technical field
The present invention relates to petrochemical industry, specifically, relate to a kind of bimetallic white spirit treating adsorbent and its preparation method and application.
Background technology
Solvent naphtha is one of five large class oil products, and the purposes of solvent naphtha is very extensive, is the oils for Cucumber being played to the effects such as dissolving, dilution, washing and extracting.The first-elected paint solvent oil (being commonly called as paint naphtha) of consumption maximum, next has edible oil, printing-ink, leather, agricultural chemicals, pesticide, rubber, cosmetics, spices, medicine, electronic unit equal solvent oil.Approximately 2,000 ten thousand tons of all kinds of white spirits of the annual consumption in the whole world, its petroleum class white spirit accounts for wherein half.Before the eighties in 20th century, white spirit of less types, change of properties is also little.But enter the later stage eighties 20th century, along with environmental requirement increasingly stringent, the consideration of white spirit user of service's health and safety is more and more subject to people's attention.
At present domestic still take No. 6, No. 120, No. 200 solvent naphthas as main product.Due to the source difference of raw material, the quality of solvent naphtha product particularly sulfur content and arene content difference is wherein larger.The primary raw material that petroleum series white spirit is produced at present has three sources, and the one, crude oil straight-run, the 2nd, catalytic reforming is raffinated oil, and the 3rd, condensate.Alkene in white spirit and arene content are the leading indicators of weighing petroleum solvent oil quality, are also the gap places of current domestic base oil solvent naphtha and external high-grade white spirit.
The de-aromatic hydrocarbons technology of white spirit has four kinds at present: hydrogenation method, sulfonation method, extraction fractional distillation and adsorption method of separation.
White spirit hydrogenation aromatics-removing method is at home and abroad most widely used, and particularly with catalytic reforming, raffinates oil and produces white spirit into raw material, and convenient because of hydrogen source, multiplex hydrogenation method is refining.But for the refinery of hydrogen source deficiency, hydrogenation aromatics-removing technology is limited, and hydrogenation method be difficult to make arene content in solvent naphtha particularly heavy aromatics content drop to 100,000/several below.
Extraction fractional distillation is take 1-METHYLPYRROLIDONE as extractant, by the method for extracting rectifying, removes the benzene in white spirit No. 6, and the method is only limited to the de-aromatic hydrocarbons of white spirit No. 6 at present.Can make its benzene content drop to 2000-3000 μ g/g(Zhang Zhihong, low fragrant solvent naphtha present situation of production technology and development trend [J]. Anhui chemical industry, 2012,38 (5): 8-10).
The alkene removing in white spirit mainly contains hydrogenation hydrogenization method and two kinds of methods of absorption method at present.The alkene of hydrogenation hydrogenization method Arene removal in raffinating oil is by catalytic hydrogenation, and this method can reduce alkene and arene content greatly, then through boiling range cutting, can obtain corresponding high-quality white spirit.But catalytic hydrogenation reaction generally needs medium-pressure or high pressure, at least also want the pressure of several MPa, the requirement to equipment and the requirement of catalyst are all higher, and this brings certain difficulty with regard to the operation of giving workman, is difficult to be widely used in the middle of the operation of actual factory.
Removing the another kind of method of alkene in white spirit is absorption method, it is that a kind of active metal is supported on X-type molecular sieve that current conventional petroleum solvent oil adsorbent adopted more, aromatic hydrocarbons in white spirit, alkene have been had higher selective, reached removing to a certain degree.For example: Chinese patent CN1891792A has set forth treating adsorbent of a kind of white spirit and its production and use, by flooding X-type molecular sieve, the preferred I A-II of nitrate solution A, VIII with nitrate solution, the nitrate solution of I B-II B family metallic element, as KNO
3, AgNO
3, Mg (NO

2.Can successfully remove the alkene in 6# and 120# white spirit, for 6# white spirit, bromine index can drop to below 400; For 120# white spirit, bromine index can drop to below 300, the arene engaging scraping rate in white spirit is reached more than 90% simultaneously, can make aromatic hydrocarbons drop to below 0.2%.
Obviously, for refining of the impurity such as deolefination aromatic hydrocarbons, still there is very large optimization space in existing petroleum solvent oil adsorbent, particularly, for improving adsorbent, with the white spirit that obtains " zero aromatic hydrocarbons zero olefin(e) centent ", be selectively a trend that meets productive life demand.
