Technical field:
The present invention relates to sweetening agent, be specifically related to a kind of concavo-convex rod gasoline desulfurizer.
Background technology:
Along with the pay attention to day by day of people to environment protection; the deep removal of sulfide in petrol is brought into schedule; this is because the existence of multiple sulfide can cause a lot of harm in the gasoline; for example make gasoline produce niff, reduce quality of gasoline, the corrosion engine; make the downstream process poisoning of catalyst; cause container swelling etc., especially can cause the pollution of environment, therefore must carry out desulfurization and handle.
Sulfide in the gasoline is of a great variety, and active sulfide comprises hydrogen sulfide, elementary sulfur, mercaptan etc., and they have stronger corrosive nature to hardware; Nonactive sulfuration owner will comprise that thioether, disulphide and thiophene etc. do not have the sulfide of corrosive nature to hardware, can become active sulfide after some nonactive sulfuration thing decomposes.
Gasoline desulfur has a variety of methods, gasoline desulfur mainly contains methods such as hydrogenating desulfurization, adsorption desulfurize, oxidation sweetening, catalytic cracking and desulfurizing, solvent extraction desulfurization and biological desulphurization, but the product that can reach deep desulfuration is also few, because the restriction of hydrogenating desulfurization on fund and hydrogen source, the research that the centering little refinery plant carries out non-hydrogenation has great importance.
Chinese patent Granted publication CN1183996C, Granted publication day is on January 12nd, 2005, name is called " iron oxide compound desulfurizer and preparation method thereof ", it disclose " novel ferric oxide desulfurizer and preparation method thereof, belonging to Fe-Zn is composite desulfurizing agent; Adopt special auxiliary agent, be composited with insoluble molysite, zinc salt active ingredient, each component concentration is (wt%): iron oxide content 30～70%, zinc oxide 5～30%, auxiliary agent 5～30%, the preparation technology of employing compression molding.The present invention has the desulfurization precision height, low cost and other advantages, alternative Zinc oxide desulfurizer is extensively owing to warm smart desulfurization in oil refinery dry gas, petroleum naphtha, coker gasoline, semi-water gas, the coke(oven)gas etc. ".
Chinese patent publication number CN CN1597088A, open day is on March 23rd, 2005, name is called " attapulgite clay desulfurization adsorptive catalyst preparation method ", it discloses, and " attapulgite clay desulfurization adsorptive catalyst preparation method relates to solid adsorbent Preparation of catalysts method, is raw material with the attapulgite clay; add compound iron, pyrolusite and water; stir, and calcination activation is carried out in extrusion molding then again.”
The all not acidified processing of attapulgite clay that above-mentioned two patents are selected, it is active and adsorptive power is relatively poor, directly has influence on the result of use of sweetening agent.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, provide that a kind of to have operational condition simple, investment and process cost are low, and sweetening effectiveness is good, does not have the concavo-convex rod gasoline desulfurizer of environmental pollution.
Concavo-convex rod gasoline desulfurizer is made up of attapulgite clay, ferric oxide, aluminum oxide, cupric oxide and zinc oxide.The preparation method of concavo-convex rod gasoline desulfurizer is after the batch mixes with concavo-convex rod gasoline desulfurizer, adds nitric acid and carries out acidification, extruding airing, crushing and screening, roasting and be packaged as finished product.
The present invention is achieved by following technical proposals:
1, batch mixes: the batching of concavo-convex rod gasoline desulfurizer, form by following component by weight percentage: attapulgite clay 65～90%, ferric oxide 1～15%, aluminum oxide 1～15%, cupric oxide 1～10% and zinc oxide 1～5%, stir mixture into concavo-convex rod gasoline desulfurizer with above-mentioned batching.
2, acidification:
1. the preparation of rare nitric acid is made up of following component: the nitric acid 1～10% of concentration 69%, water 90～99% by weight percentage;
2. acidifying: the batching of acidification, form by following component by weight percentage: the mixture 45～65% of concavo-convex rod gasoline desulfurizer, rare nitric acid 35～55%, rare nitric acid is slowly added in the mixture of concavo-convex rod gasoline desulfurizer and carry out acidification, stack activation 24～72 hours after the acidification.
3, extruding airing: with the mixture of the concavo-convex rod gasoline desulfurizer after the acidifying, push by extrusion machine and to be flap, the thickness of flap≤3 millimeter are transported to cement court and carry out airing, the moisture of mixture≤15% after the airing.
4, crushing and screening: mixture after the airing is broken for irregular particle, and sieves with vibratory screening apparatus, the compound particles fineness is controlled at 0.105～3.0 millimeter.
5, roasting packing: carry out roasting in the compound particles input stoving oven after will sieving, maturing temperature is controlled at 300～350 ℃, and roasting time was controlled at 1.5～3 hours, was packaged as the finished product of concavo-convex rod gasoline desulfurizer after the cooling.
Concavo-convex rod gasoline desulfurizer is a kind of irregular particle, attapulgite clay is after the peroxy-nitric acid acidification, have that specific surface area is big, porosity is high and the pore passage structure characteristic of simple, its activity and decoloring ability all are greatly improved, absorption and filtering effect are very remarkable, gasoline is adsorbed to the mercaptan in the gasoline, disulphide, thioether and thiophene-based sulfides in its particle with after concavo-convex rod gasoline desulfurizer fully contacts, and has reduced the sulfide content in the gasoline; Ferric oxide in the concavo-convex rod gasoline desulfurizer, aluminum oxide, cupric oxide and zinc oxide generate nitrate after the peroxy-nitric acid acidification, produce chemical reaction with the sulfide in the gasoline, thereby further reduce the content of sulfide in petrol, measure through test of many times, the desulfurization degree overall target of concavo-convex rod gasoline desulfurizer on average reaches more than 95%.
