Abstract
The present invention relates to one kind of 2.4 mm coal-carrier active carbon and its use. The active carbon has the technological indexes including: grain size 2.1-2.7 mm, carbon tetrachloride adsorbing value 80-100 %, strength 85-98 %, iodine value 1000-1200 mg/g, bulk density 350-500 g/L, ash 4-15 %, pH 5-9 and iron content less than 0.5 wt%. It is used as carrier of zinc acetate catalyst for synthesizing vinyl acetate in fixed bed and has excellent use effect.
Description
The present invention relates to the synthetic field of organic chemical industry, carrier active carbon in particularly a kind of synthesizing vinyl acetate and uses thereof.
With the coal is the gac of raw material production, be mainly used in water treatment, air purification field, the vinylon synthesis and production process has two kinds, a kind of is the fluidized-bed Catalytic processes, another kind is a fixed-bed catalytic technology, fluidized-bed synthesis method catalyst system therefor adopts the wooden or coal mass active carbon of 24-48 purpose as support of the catalyst, and the fixed bed synthesis method is not all right with above-mentioned carrier.
The purpose of this invention is to provide a kind of 2.4 mm coal-carrier active carbons that are suitable for the fixed bed synthesizing vinyl acetate and uses thereof.
The present invention realizes by following scheme:
2.4 mm coal-carrier active carbon, its technical indicator is:
Granularity Ф 2.4 ± 0.3mm
Tetracol phenixin adsorptive value (CTC): 80-100%
Intensity: 85-98%
Iodine number: 1000-1200mg/g
Bulk density (BD): 350-500g/L
Ash (Ad): 4-15%
PH value: 5-9
Iron level:＜0.5% (W)
Machining process comprises the feed coal abrasive dust, adds binding agent, stirring, moulding, cool bar, charing, activation, chemical treatment, drying, screening, packing;
Chemical treatment is to carry out cleanup acid treatment with activating the strong acid of qualified material with proper concn, is 5-8 with water rinse to pH value then;
2.4 the purposes of mm coal-carrier active carbon is the carrier that is used for fixing zinc acetate catalyst in the synthesizing vinyl acetate.
The present invention tries out in vinylon manufacturer, proves that it can reach processing requirement fully, makes more than the extension of validity to 100 day of catalyzer, and rate ratio does not adopt and improves 30% when of the present invention.
Embodiment:
Production method: feed coal is selected ash 3-8% for use, fugitive constituent is the Taixi anthracite of 6-12%, binding agent is coal tar and coal-tar pitch, forming mould opening Ф 3.6 ± 0.3mm, weight proportion: coal dust: tar: pitch=100: 10～40: 0～30, cool bar after the moulding, advance the charring furnace charing again,, carry out the pickling chemical treatment then through the activation of SLP stove, handling and adopting strong acid is clean-out system, want rinsing to PH5～9 then, then, drying, screening, packing, the technical indicator that obtains product is: granularity Ф 2.4 ± 0.3mm, tetracol phenixin adsorptive value (CTC): 80-100%, intensity: 85-98%, iodine number: 1000-1200mg/g, bulk density (BD): 350-500g/L, ash (Ad): 4-15%, pH value: 5-9, iron level:＜0.5% (W).
The present invention is adsorbed in zinc acetate on the gac of the present invention as the carrier of fixed bed synthesizing vinyl acetate zinc acetate catalyst, advances reaction unit then, and effect is than good with zinc acetate merely, can prolong zinc acetate work-ing life more than 100 days.
Claims (3)
1.2.4 mm coal-carrier active carbon is characterized in that its technical indicator is:
