Abstract
The mesh proppant consists of powder material in 91-99 wt% and pore forming agent in 1-9 wt%. The powder material is compounded with kaolin, clay, flux, alumina powder in certain proportion and has alumina content of 20-90 wt%; and the pore forming agent is polystyrene or rosin. The powder material and the pore forming agent are crushed, sieved and mixed, and the mixture is rolled while adding water, kneaded into various shape and high temperature sintered to form the mesh proppant. The mesh proppant has the identical mechanical strength, acid and alkali resistance, chemical corrosion resistance, small specific weight, high porosity, low reactor load, long catalyst life and high production efficiency.
Description
Technical field
The present invention relates to the proppant of industry catalyst reactors such as a kind of chemical industry, oil, chemical fertilizer, especially a kind of lightweight mesh proppant.
Background technology
In industries such as chemical industry, oil, chemical fertilizer, generally use by after kaolin, clay, flux and the aluminium oxide powder mixed grind at present, burn a kind of high-gravity filler form through high-temperature baking and support, cover catalyst in the reactor.Though this proppant has mechanical strength and acidproof, alkaline-resisting and chemical resistance preferably, it is than great, and hole is few.When the feedstock oil grade reduces, during impure increasing, this proppant can not prevent that catalyst from sink the carbon coking, and adsorbs with to separate harmful substance ability such as sulfide little.Thereby, not only increasing the load of reactor column bed, and the catalyst action time is shortened, production efficiency reduces, and cost increases.
Technology contents
Great at the ratio that above-mentioned proppant exists, the problem that hole is few, the invention provides a kind of not only have same mechanical strength and acidproof, alkaline-resisting and chemical resistance, and proportion is little, and hole is many, and the table specific area is big, thereby can alleviate reactor load, strengthen absorption and separate the harmful substance ability, enhance productivity, prolong the mesh proppant of on-stream time.
Mesh proppant of the present invention is made up of powder, pore creating material, and its percentage by weight is: powder 91-99; Pore creating material 1-9.
Powder of the present invention is made up of kaolin, clay, flux, aluminium oxide powder, and its percentage by weight is: kaolin 10-50; Clay 5-25; Flux 10-25; Aluminium oxide powder 5-75, the content of alundum (Al in the described kaolin of root a tree name, clay and the flux adds the aluminium oxide powder of Different Weight percentage again, is mixed with the powder that alundum (Al content is 20%-90%; Described flux is potassic feldspar or talcum; Described kaolin and clay are that ferric oxide content is all smaller or equal to 0.8% high-quality china clay; Described pore creating material is polystyrene or rosin.
The manufacture method of mesh proppant of the present invention is:
1, kaolin, clay, flux are removed foreign material, bake to its moisture content smaller or equal to 3%, mix by said ratio, pulverize with pulverizer, sieve with 250-325 eye mesh screens.
2, the content of alundum (Al and powder require the content of alundum (Al to calculate in root a tree name kaolin, clay and the flux, the aluminium oxide powder that adds Different Weight percentage, be mixed with the powder that alundum (Al content is 20%-90%, the alundum (Al of every increase by 5% content is a grade in the powder, and promptly alundum (Al content is 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% 15 grade.
3, this step manufacture method has dual mode: first kind (3-a) makes diameter with polystyrene is the proppant of 10-80 millimeter; Second kind (3-b) makes diameter with rosin is the proppant of 1-9 millimeter.
3-a: with specification is that 0.8-2 millimeter and specification are greater than 2 millimeters but through 120 minutes polystyrene spheres of 110 degree constant temperature, be 1-9 by weight percentage, join in the powder of different brackets, add an amount of water again, with mixer mixing 20-30 minute, it is defocused to go out slotted weight, covered old 5-7 days with film,, be cut into the cylindric moulded pottery not yet put in a kiln to bake of suitable length again with extruding slivering in the vacuum deairing machine, rub glomeration with hand rubbing, rubbing into diameter with hand rubbing repeatedly again in the sulphur die cavity is 10-80 millimeter spheroid, bake do after, be presented in the sintering furnace again, burnt 4-8 hour in-1550 degree bakings of 1280 degree, come out of the stove after the cooling.
3-b: with specification is the rosin of 0.1-0.4 millimeter; be 1-9 by weight percentage; join in the powder of different brackets, after 20-30 minute, progressively be added to again and ward off in the machine with the mixer mixing; add an amount of water; base substrate is grown up is the spherula of 1-9 millimeter, bake do after, be presented in the sintering furnace again; burnt 4-8 hour in the baking of 1280-1550 degree, come out of the stove after the cooling.
Mesh proppant proportion of the present invention is 0.65-1, and porosity is 25%-35%, with its support, cover on the catalyst, thereby reactor load is little, the objectionable impurities ability is strong in absorption and the separate reactor, and the catalyst action time is increased, and has improved production efficiency.Mesh proppant specification, wide in variety extensively is adapted to support in the industry reactors such as chemical industry, chemical fertilizer, oil covering catalyst and uses simultaneously.
