Subject: Ding Xinda activated carbon adsorption rate
Content: By single factor experiment, the optimal conditions of carbon production were obtained as follows: pyrolysis temperature 600 ℃ , activator concentration 4 mol · L', pyrolysis time 1.5h, solid-liquid ratio 1:2.5.Orthogonal experiment showed that the influence of each factor was as follows: pyrolysis temperatureIs the activator concentration Pyrolysis time >Solid-liquid ratio.(4) the main performance of PAC is basically equivalent to 8818 type activated carbon; www.powdered-activated-carbon.com The concentrations of heavy metals in activated carbon leaching solution of sludge were all qualified.Compared with domestic and foreign research reports, the quality of PAC is in the middle level.(5) Compared with SAC, the specific surface area of PAC is larger, up to 636.8m2 · g'. PAC is mainly mesoporous, but also contains some micropores. The adsorption/desorption isotherm shows that PAC is activated carbon with parallel wall slit pore structure. imagitarium activated carbon pellets
