Embodiment 1

[0020] Embodiment 1: as figure 1 Shown, a kind of processing method that prepares granular activated carbon with Xantho sorbifolia husk is made up of following steps: (1) pulverizes Xantho sorbifolia seed husk, dries after the pretreatment of sieving, pulverizes and sieves again, selects 20 order granules , The pulverized material of Demania crocus seed shell is dried in a constant temperature electric drying oven, and the drying in the drying oven requires a constant temperature, and the temperature is 90°C. Reduce the moisture content of the crushed sorbifolia seed shells to below 10%; put the pretreated radix sorbifolia granules into a pulverizer for further crushing, crush the radix sorbifolia shells and sieve them, and select 60-mesh radix sorbifolia fruits shell particles;

[0021] (2) acid leaching: get the phosphoric acid solution that the mass percentage concentration is 60%, the sorbetia sorbifolium seed shell pulverization thing in the step (1) and the phosphoric a...

Abstract

The invention discloses granular activated carbon prepared from xanthoceras sorbifolia bunge aril and a process thereof. The process comprises the following steps: (1) smashing the xanthoceras sorbifolia bunge aril, drying and then smashing after pretreatment (namely sieving); (2) carrying out acid leaching; (3) drying and activating; and (4) rinsing, drying and sieving so as to obtain the finished activated carbon. The method has the advantages that the xanthoceras sorbifolia bunge aril as a raw material for preparing the activated carbon is abundant, and the raw material is from processing residues of xanthoceras sorbifolia biodiesel so that waste is turned into wealth; based on the xanthoceras sorbifolia bunge aril as the raw material, and the activated carbon is prepared by a phosphoric acid solution activation process, thus the preparation process is simple, the production cost is reduced, the pollution is less, and the activated carbon is easy to regenerate and is good in chemical stability; and the activated carbon prepared by the phosphoric acid solution activation process has the advantages of large specific surface area and good absorption property.

Description

Technical field: [0001] The invention relates to an activated carbon and a process method, in particular to a granular activated carbon prepared from xanthus sorbifolia fruit shell and a process method. Background technique: [0002] Adsorption is an important technology in the separation and purification process. Among many adsorption materials, activated carbon has been most widely used because of its large adsorption capacity and low cost. Widely used in chemical industry, environmental protection, food and pharmaceutical, catalyst carrier and electrode material and other fields. The Inner Mongolia Autonomous Region is the main producing area of ​​X. sorbifolium. The processing and utilization of X. sorbifolia husk and other residues to turn waste into treasure is of great significance to the comprehensive utilization of X. sorbifolia and the construction of a conservation-oriented society. [0003] Xanthoceras sorbifolia Bunge is a woody oil crop of the genus Xanthocera...
