Problems solved by technology

[0003] In the existing reports on the use of distiller's grains to prepare biomass-based activated carbon, more activated carbon is directly obtained by high-temperature carbonization and then activated by KOH or water vapor, but there is a lack of a simple process for the preparation of distiller's grain-based activated carbon modified by nitrogen heteroatoms. The modification of nitrogen heteroatoms to treat activated carbon is an effective means to improve the catalytic activity or adsorption activity of activated carbon.

Abstract

The invention discloses modified baijiu distiller grain-based activated carbon and a preparation method thereof. The method comprises the following steps: (1) crushing dried baijiu distiller grain andcarbonizing the baijiu distiller grain at 600-900 DEG C in a nitrogen atmosphere for 1-5 hours, ultrasonically mixing the carbonized baijiu distiller grain with an activating agent, carrying out a hydrothermal reaction, and filtering, washing and drying the product to obtain activated carbon; and (2) soaking the activated carbon in a nitrogen source solution with the mass fraction of 0.01%-0.5% for 3 hours, and filtering, drying and calcining the activated carbon at 650-950 DEG C for 1-5 hours in a nitrogen protective atmosphere to obtain the modified baijiu distiller grain-based activated carbon. The method is simple, easy to operate and suitable for industrial production. The baijiu distiller grain-based activated carbon has a large specific surface area and rich pore structure properties and embodies excellent performance of adsorbing and catalytically oxidizing to remove organic pollutants in a water body.

Description

technical field [0001] The invention belongs to the technical field of activated carbon preparation, and in particular relates to a modified distiller's grain-based activated carbon and a preparation method thereof. Background technique [0002] As a large liquor country in my country, while the liquor industry has developed rapidly and well in recent years, a large amount of distiller's grains are inevitably produced in the liquor brewing process. Pile up a large number of distiller's grains not only seriously occupy limited land resources, but also pollute the atmosphere, soil, surface water and groundwater due to the decay of distiller's grains. In addition, as a secondary resource, distiller's grains are rich in nutrients such as crude protein, crude fiber, crude fat, starch, and vitamins. If they cannot be effectively utilized as resources, they will also be a serious waste of resources. Therefore, the development of efficient resource utilization methods of distiller'...
