Abstract
The invention relates to adsorbent for adsorptive desulfurization of fuel oil. An adsorbent composition contains a metal promoting agent, zinc oxide, an AEL-type structured phosphoaluminate molecular sieve and an oxide carrier. At least a part of promoting agent metal exists in a reduction state. A method for preparing the adsorbent composition comprises the steps of forming, roasting and reducing a mixture containing a zinc compound, a promoting agent metal compound, an oxide carrier component and the AEL-type structured phosphoaluminate molecular sieve. The adsorbent composition is applied to adsorptive desulfurization of hydrocarbon oil and has a better desulfurization effect; furthermore, the octane value of cracked gasoline can be increased; and the low-temperature flowing property of diesel can be improved.
Description
Technical field
The present invention relates to a kind of adsorbent composition for hydrocarbon ils adsorption desulfurize and methods for making and using same thereof.
Background technology
Compare with hydrogasoline with direct steaming gasoline, the content of FCC sulfur in gasoline, alkene, aromatic hydrocarbons is higher, and stability is poor, easily produce colloid, foul smelling, corrosion and colour difference, although its research octane number (RON) can reach 90 left and right, can not directly use as qualified motor petrol.Simultaneously, along with improving constantly of environmental requirement, people's environmental consciousness is also in continuous change, the environmental pollution that the fuel consume that how to reduce increases day by day brings, become the major issue that petroleum refining industry and auto industry sustainable development face, production super-low sulfur, zero-emission fuel are the general trends of petroleum refining industry's development.
The method that removes the sulphur in gasoline has hydrodesulfurization and adsorption desulfurize.Hydrodesulfurization, although can remove the sulfur-containing compound in gasoline, can make the most of olefin saturated in gasoline, and octane number (organon and motor octane number) significantly declines; And some thiophene compound in gasoline, due in sterically hindered effect, is difficult to adopt common method of hydrotreating to remove, required condition harshness, this may make part aromatic saturation, thereby octane number is further declined.Adsorption desulfurize, for example S-Zorb adsorption technology [Zhao Xunzhi, Cheng Zhilin. the progress of low-sulfur clean fuel oil production technology. Industrial Catalysis .2007,15 (6): 1-5] be a kind of adsorption desulfurize technology of facing hydrogen, there is good gasoline desulfur effect, and the decline of octane number (organon and motor octane number) is less, but need suitable adsorbent.
CN 1130253 C disclose two kinds of similar S-Zorb adsorbent and production methods thereof with CN 1258396C.Adsorbent comprises zinc oxide, silica, aluminium oxide and metal simple-substance nickel or cobalt.But the motor octane number decline 0.1-0.4 of gasoline.
CN 1327988 A disclose a kind of S-Zorb adsorbent, it is to pass through promoter, as the precursor of nickel, nickel oxide or nickel oxide floods the adsorbing agent carrier that comprises zinc oxide, expanded perlite and aluminium oxide, then make the chemical valence of the promoter metals in the promoter metals adsorbing agent carrier composition of gained reduce, prepare wear-resisting adsorbent composition.This adsorbent is applied to S-Zorb technology, and after desulfurization, the average octane number Δ (RON+MON)/2 of cracking gasoline declines.
Although above existing desulfuration adsorbent can reduce the sulfur content in cracking gasoline, can not improve the octane number of gasoline, and may cause the loss of octane number; And do not relate to for diesel oil adsorption desulfurizing and reduce condensation point of diesel oil.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hydrocarbon ils adsorption desulfurize adsorption-desulfurization sorbent composition, and this adsorbent composition has good adsorption desulfurize ability, and can improve the condensation point of octane number and reduction diesel oil; The other technical problem that the present invention will solve is to provide preparation method and application's method of described adsorbent composition.
The invention provides a kind of hydrocarbon ils adsorption-desulfurization sorbent composition, this adsorbent composition comprises:
(a) zinc oxide,
(b) AEL structure aluminophosphate molecular sieve,
(c) oxide carrier, and
(d) promoter metals;
Take the weight of adsorbent composition as benchmark, in described adsorbent composition, AEL structure aluminophosphate molecular sieve content is 1～40 % by weight, take the content of element promoter metals as 5～50 % by weight; The content of zinc oxide is 10～80 % by weight; The content of oxide carrier is 10～84 % by weight; At least part of described promoter metals exists with reduction-state.
The invention provides the preparation method that described adsorbent composition is also provided, comprising: form and comprise particle, the roasting of zinc compound, promoter metals compound, oxide carrier component and AEL structure aluminophosphate molecular sieve, the step of reduction.
The present invention further provides a kind of hydrocarbon ils desulfurizing method by adsorption, comprise the step that hydrocarbon ils is contacted with adsorbent, it is characterized in that, described adsorbent is adsorbent composition provided by the invention.
