Because of these pores, especially the micropores provide a large surface area.
activated charcoal manufacturersThe pore volume of activated carbon micropores is generally only 0.25-0.9mL/g, the number of pores is about 1020 lg, and the surface area of all micropores is about 500-1500m2/g, which is usually measured by the BET method, and it is also said to be as high as 3500-5000 m2/g.
gold recovery activated carbonActivated carbon almost more than 95% of the surface area is in the micropore, so in addition to some macromolecules can not enter, micropore is an important factor to determine the adsorption performance of activated carbon.The granular activated carbon with high strength was prepared by heating wood phosphate mixture at low temperature and using tar generated during its pyrolysis as binder.
In this paper, the process conditions and plasticizing mechanism of granular activated carbon prepared by phosphoric acid were studied, which provided scientific data and theoretical basis for the preparation of high strength granular activated carbon.
Fir chip as the raw materials, H - POs as activator, using single factor analysis and orthogonal experimental design method, this paper discusses the influence granular activated carbon pore structure and the iodine adsorption value, methylene blue and strength of various preparation factors, determine the optimum process conditions of preparation of granular activated carbon phosphoric acid, phosphoric acid concentration is 70%, dipping 180%, kneading temperature is 170 ℃, for 60 min kneading time, activation temperature is 350 ℃, the activation time of 210 min.Stability is reflected in the fact that the economy performed within an appropriate range, growth became more stable, and the quality and performance of the economy continued to improve.
The economic structure has continued to improve. Innovation is playing an increasingly important role in underpinning development. The service sector accounts for a larger share of the economy, and consumption is contributing more to growth.
