Embodiment 1

[0021] Experimental group: Sawdust is screened to remove wood blocks and silt, and then dried to remove part of the water and then mixed with activator phosphoric acid and auxiliary agent sulfuric acid. The ratio of anhydrous sawdust, phosphoric acid and sulfuric acid is 1.0:0.7:0.1. The mixture input The activation furnace is used for carbonization and activation, the activation temperature is 450-500°C (material temperature), and the activation time is 40-60 minutes. After recovering phosphoric acid and sulfuric acid from the activated material, the residual acid is further washed to make the pH value reach 3.5. Then dry it so that the moisture content is less than 10%, and then send it into precision crushing and sieving to control the particle size of the activated carbon powder to be 100-120 mesh. Finally, the product is adjusted so that the adsorption capacity of methylene blue is 7-8ml; the decolorization rate of caramel is 45-50%; the granularity of activated carbon po...

Abstract

The invention provides special-purpose active carbon active carbon for removal of plasticizers in liquor, and the special-purpose active carbon active carbon is characterized in that: the methylene blue adsorption capacity of the activated carbon is 6-9 ml, and caramel decoloration rate is 30-60%. The invention also provides a production method and a use method of the active carbon. The special-purpose active carbon can effectively remove the plasticizers dissolved in the liquor, at the same time, main aroma types of various kinds of liquor can be maximumly retained, and the special-purpose active carbon is easy to remove without introduction of impurities.

Description

technical field [0001] The invention relates to a special activated carbon for removing plasticizers in liquor and a preparation method thereof. Background technique [0002] Jiugui Liquor, known as the "Supreme Wonder", has been among the ranks of high-end baijiu. On November 19, 2012, it was detected that the plasticizer exceeded the standard by 2.6 times. In fact, the plasticizer in liquor had been discovered long ago. The plasticizers in liquor mainly come from plastic wine barrels, plastic wine delivery pipes, latex pipes for wine pumps, plastic cloth for sealing wine tanks, plastic inner covers for finished wine, plastic bags for finished wine, plastic bottles for finished wine, and finished wine plastic bottles. Wine plastic barrel packaging, etc. Finished wine in plastic bags and bottles will gradually increase in plasticizer content over time. The highest value of plasticizer dissolved in liquor products is the latex tube of the wine pump, which is currently used...
