The industrial production of catalytic activated carbon begins with the selection of raw materials. Plant-based raw materials such as coconut shells or fruit shells need to be crushed and screened to 2-4mm particles and the ash content should be controlled below 5%. When the physical method is adopted in the activation stage, it needs to be continuously activated in a steam environment at 850℃for 6 to 8 hours. If the chemical method is selected, the raw materials should be immersed in a 40% concentration ZnCl₂ solution and then undergo carbonization treatment at 600℃. Special attention should be paid to the fact that the wastewater generated by the chemical method must go through strict treatment processes such as neutralization and precipitation.
To enhance product performance, acid modification treatment is required. Usually, a mixed solution of HF and HNO₃ is used for etching to expand the microporous structure, or nitrogen-containing functional groups are introduced through ammonia water modification to strengthen the anchoring ability of metal ions. The quality control system consists of three core indicators: the iodine adsorption value should be greater than 1000mg/g, the carbon tetrachloride adsorption rate should not be less than 60%, and the bulk density should be strictly controlled within the range of 0.45-0.55g/cm³. The current technological frontier of the industry focuses on the application of microwave activation technology, which can reduce energy consumption by 30%, as well as the research and development of new environmentally friendly processes using biomass Mallmetoder som halm . Produktionsföretag måste ägna särskild uppmärksamhet åt att erhålla föroreningar i föroreningar i enlighet med lagen, och allt processavloppsvatten måste släppas upp till standard .
