Abstract
The present invention discloses a preparation method for adsorption filtration agent of aviation kerosene. The present invention has the technical scheme that the preparation method for adsorption filtration agent of aviation kerosene comprises proportioning, acidification, extrusion, calcination, pulverization and finished product package. The adsorption filtration agent of the aviation kerosene has the ingredients of attapulgite clay, zeolite, bergmeal and sawdust. The adsorption filtration agent of the aviation kerosene has the advantages of small irregular granular appearance shape, high porosity, good granular strength, stable performance, high oil yield, regenerating reuse for many times and production cost reduction. The present invention is suitable for the refining treatment process of the adsorption filtration of the aviation kerosene and is also suitable for the refining treatment process of the adsorption filtration of other petroleum products.
Description
Technical field:
The present invention relates to filtering agent, be specifically related to a kind of production method of aviation kerosene absorption filter agent.
Background technology:
Aviation kerosine claims jet fuel again, mainly is used as the fuel of jet engine.The characteristic that aviation kerosine should possess is: high-level performance and having good burning performance, can guarantee burning fully, stable, carbon deposit is little, smolder few, does not produce vapour lock in high-altitude flight, evaporation loss is little; Freezing point is low, and low temperature flow is good; Sulphur and mercaptan sulfur content are low, have low-corrosiveness, no stink; The smoke point height, luminometer number is suitable, Fire Radiation ability appropriateness; Good security, normal temperature are stored not perishable down, and the gum deposit thing that generates under higher serviceability temperature is few; Refining deep, cleanliness is good; Lubricity and wear resistence are good.
Aviation kerosine is in refining process; the oxious components such as moisture, mechanical admixture, sulphur and mercaptan sulfur that can contain trace usually; and the specific stimulation stink arranged; if the oil product resting period is longer; these impurity are because of chemistry or physical action; can cause product colour further to deepen, the serviceability of oil product is reduced.Oil plant adopts soda acid to come refining usually, and the soda acid refining not only has certain danger, and oil product loss in the process of refining is also big, adds the bad processing of waste residue again, causes reasons such as secondary pollution.Oil plant uses atlapulgite or activated carbon to carry out adsorption bleaching refining aviation kerosine mostly.Use atlapulgite or activated carbon refining aviation kerosine that certain effect is arranged, but the contained composition of atlapulgite or activated carbon is more simple, can not make the aviation kerosine refining reach a better level.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of production method of simple to operate, aviation kerosene absorption filter agent that adsorption filtration is effective is provided.
The production method of aviation kerosene absorption filter agent is: batching, acidifying, extruding, roasting, pulverize, be packaged as finished product.
Aviation kerosene absorption filter agent is made up of Concave-convex clay rod, zeolite, diatomite and wood chip.
Concave-convex clay rod be a kind of tool chain layer structure contain Shuifu County's magnesium silicate clay mineral, have another name called palygorskite, after acidified modified, be activated attapulgite, have heat endurance, caking property, adsorptivity and higher decoloring ability preferably.
Zeolite is a kind of alumino-silicate ore, ion exchangeable is one of zeolite rock critical nature, cation such as K, Na, Ca and hydrone combine not tightly with screen work in the cavity in the zeolite lattice (hole), very easily with its ambient water solution in cation generation exchange interaction, the zeolite lattice structure after the exchange is not destroyed yet.Having very big specific area (500～1000 meters squared per gram) thereby can produce bigger extension, is a kind of outstanding adsorbent.Because zeolite has very big absorption surface, can hold the adsorbent of quite a lot of quantity, thereby can impel chemical reaction to carry out in its surface, so zeolite is catalysis, cracking agent and the carrier of effective oil.
Diatomite is a kind of biogenic silicastone, and specific area is big, and unit weight is low, the porosity height, can absorb the water of 1.5～4 times of itself weight, have characteristics such as exquisiteness, loose, light weight, porous, suction and permeability are strong, be as the absorption filter aid in the present invention.
Wood chip generates activated carbon in roasting process, can also increase the micropore of aviation kerosene absorption filter agent granule interior, further improves the adsorption filtration effect of aviation kerosene absorption filter agent.
The present invention is achieved by following technical proposals:
1, the batching of aviation kerosene absorption filter agent comprises following component by weight percentage: Concave-convex clay rod 35～65%, zeolite 15～35%, diatomite 10～30% and wood chip 5～10%.
2, use mixer to mix above-mentioned batching after, add concentration and be 2～10% sulfuric acid solution and carry out acidification, the acidification time was controlled at 24～48 hours, to improve the activity of aviation kerosene absorption filter agent, increased the ability of its adsorption cleaning.
3, through the mixture of acidification, be transported in the extruder and push, the tablet after the extruding is transported to that dryer activates and roasting, and sintering temperature is controlled at 320～450 ℃, the moisture of tablet≤2%.
4, the tablet after the oven dry is transported in the disintegrating machine to pulverize and is irregular granule, and granularity should be controlled at 0.1～2.0 millimeter, is packaged as finished product.
5, using method: earlier with aviation kerosene absorption filter agent, join the bottom of filter, add the aviation kerosine that needs adsorption filtration again, the particulate of oxious component, moisture and mechanical admixture in the aviation kerosine, being adsorbed agent filters adsorbed, limpid transparent aviation kerosine is discharged from oil-out, finishes the technical process of adsorption filtration.
The aviation kerosene absorption filter agent outward appearance is irregular fine granularity, the porosity height, and granule strength is good, stable performance, the oil yield height, renewable repeatedly use reduces production costs.Be applicable to the adsorption filtration refining treatment technology of aviation kerosine, also be applicable to the adsorption filtration refining treatment technology of other oil product.
The specific embodiment:
Below in conjunction with embodiment, the invention will be further described:
1, the batching of aviation kerosene absorption filter agent comprises following component by weight percentage: Concave-convex clay rod 50%, zeolite 30%, diatomite 12% and wood chip 8%.
2, use mixer to mix above-mentioned batching after, add concentration and be 5% sulfuric acid solution and carry out acidification, the acidification time is 24 hours.
3, the mixture after the acidification is transported to pushing in the Roll extruder, and extruding back tablet is transported to that dryer is dried and roasting, and sintering temperature is controlled at 320～450 ℃, the moisture of tablet≤2%.
4, the tablet after the oven dry is transported in the disintegrating machine to pulverize and is irregular granule, and granularity should be controlled at 0.1～2.0 millimeter, is packaged as finished product.
