The surface functional group structure and specific surface area of the modified GAC were changed, and the changes of the surface functional group structure and specific surface area of the activated carbon prepared by different modification methods were different.
https://www.dxdcarbon.com/The specific surface area of activated carbon modified by nitric acid increased from 925.45m'lg to 960.52m2/g, and the number of acid functional groups (carboxyl group, phenolic hydroxyl group) increased from 0.23 mmol/g to 0.36 mmol/g, while the number of acid functional groups and specific surface area of activated carbon modified by reduction decreased.In activated carbon adsorption characteristics of mercury in flue gas of experiments, the experimental results show that:
https://www.dxdcarbon.com/product-category/activated-carbon the preparation of activated carbon and commercial activated carbon has the same ability to mercury, commercial activated carbon on mercury adsorption efficiency was 53.5%, the biggest physical activation, the preparation of activated carbon on mercury adsorption efficiency was 47.5%, the largest chemical activation of the activated carbon prepared by the biggest adsorption efficiency for the mercury is 57.64%.The touch screen is used to realize the human-computer interaction function, and the monitoring system is established to monitor the process parameters such as temperature and pressure in real time. The functions of setting formula, alarm and curve recording are set up to meet the monitoring situation of the production site.
