Abstract
A supporting protection body and a manufacture method thereof are characterized in that the manufacture method comprises the following steps: taking kaolin, feldspar and wood chips as materials, mixing the materials according to the following weight ratio: 40-60 of kaolin, 25-40 of feldspar, and 5-10 of wood chips; the supporting protection body is manufactured after the steps of mixing to prepare dry powder, removing ion after sieving, molding after grain enameling or die-stamping, and calcining; and the supporting protection body is spherical or column-shaped or trapezoid-shaped. The supporting protection body is provided with a great deal of mesh honeycomb structures, thereby greatly improving the space volume of the supporting protection body, accelerating the fluidity of the oil inside the supporting protection body, enhancing the dirty-containing capability of the supporting protection body for impurities, deposited gum and coke in oil, preventing premature carbon deposition andcoking jam of catalyst, prolonging the service life of the catalyst, reducing the pressure of a reactor, improving the running period of a fixed bed reactor, reducing the oil refining cost, and increasing the economic benefits of enterprises.
Description
Technical field
The present invention relates to a kind of supporting protection body that is used for oil, chemical plant installations reactor guard catalyst and preparation method thereof.
Background technology
At present, at oil, when passing through reactor in the chemical industry refining, because existing beds is subjected to the influence of its structure and material, its catalyst impurities adsorption capacity is mostly more weak, simultaneously, the support packing layer of catalyst still adopts adsorption capacity and the less inertia alumina ball of sediment space, thereby impurity not only can stop up the oil and gas pipes in the reactor, makes the pressure in the reactor fall rising, and easily caused too fast heavy carbon of catalyst and coking, shorten the service life of catalyst, so both influenced the normal cycle of operation of reactor, increased the consumption of catalyst again, influence refinery output, increase the processing cost of oil refining, reduce economic benefit.
Summary of the invention
At the problem that catalyst in the above-mentioned existing technology in use exists, the present invention proposes a kind of make difficult fast heavy carbon of catalyst and coking, strengthen absorption impurity ability, prevent the pressure drop rising, guarantee the supporting protection body that reactor can run well.The technical scheme that the technical problem to be solved in the present invention is taked is: be raw material with kaolin, feldspar, wood chip mainly, press the weight ratio of component: kaolin 40-60, feldspar 25-40, wood chip 5-10, the spherical in shape or cylindricality, trapezoidal of the shape of supporting protection body.Its preparation method is as follows:
One, takes by weighing kaolin, feldspar and wood raw material by the weight ratio of component and evenly mix, make dry powder;
Two, dry powder is added pulverize in the pulverizer after, send into that vibratory sieve sieves and deironing is handled;
Three, will sieve and the dry powder of deironing wards off that grain is rolled into spheric granules or in mould compacting form idiosome,
Four, the moulding idiosome is sent in the calcining furnace, be heated to the 1200-1300 roasting, be incubated 7---8 hour,, can make supporting protection body with coming out of the stove after the stove cooling.
Supporting protection body of the present invention works the guard catalyst effect of supporting; it is that the plurality of raw materials mixed calcining forms and has a large amount of netted honeycomb porous structures; thereby improved the spatial volume of supporting protection body greatly; accelerated the flowability of oil in supporting protection body inside; impurity and the appearance dirt ability that deposits colloid and coke powder in the supporting protection body absorption oil have been strengthened; guarantee heavy carbon and coking that catalyst can be not too early; prolonged the service life of catalyst; the pressure that has reduced reactor falls; improved the service cycle of fixed bed reactors; reduce the oil refining cost, increased economic benefit of enterprises.
Kaolin among the present invention is the skeleton raw material, and feldspar is the consolidation raw material, and wood chip is the pore-forming raw material.
Specific embodiment
Supporting protection body of the present invention is by being made as following method step:
The first step: the weight ratio by component takes by weighing kaolin-55, feldspar-35, wood chip-10 composition, after evenly mixing, makes dry powder;
Second step: with dry powder add pulverize in the pulverizer after, send into and sieve in the vibratory sieve and deironing is handled;
The 3rd step: will be above-mentioned have sieved and the dry powder of deironing is warded off grain and is rolled into spheric granules, or in mould compacting formation idiosome;
The 4th step: the moulding idiosome is sent in the calcining furnace, be heated to 1250 roastings, be incubated 7 hours,, can make how empty spherical supporting protection body with coming out of the stove after the stove cooling.
Claims (2)
1. supporting protection body; it is characterized in that it is a raw material with kaolin, feldspar, wood chip; weight ratio by component takes by weighing kaolin 40-60, feldspar 25-40, wood chip 5-10, is made through being mixed and made into the dry powder-deironing of sieving-ward off grain or compression molding-calcining step.
2. method for preparing the described supporting protection body of claim 1 is characterized in that: take by weighing kaolin, feldspar and wood raw material by the weight ratio of component and evenly mix, make dry powder; With dry powder add pulverize in the pulverizer after, send into that vibratory sieve sieves and deironing is handled; To sieve again and the dry powder of deironing is warded off grain and is rolled into spheric granules, or compacting forms idiosome in mould; At last the moulding idiosome is sent in the calcining furnace, be heated to the 1200-1300 roasting, be incubated 7---8 hour,, can make supporting protection body with coming out of the stove after the stove cooling.
