| titleOfInvention | MgO in-situ modified biochar VOCs adsorbent and its preparation method and application |
| abstract | The invention discloses an MgO in-situ modified biochar VOCs adsorbent, a preparation method and application thereof. The method adopts magnesium acetate as an alkali source to inject biochar, then mixes it with a potassium hydroxide activator, washes and leaches K + , and the two After sub-high temperature carbonization, uniformly dispersed MgO was formed on the biochar in situ, and the MgO in-situ modified biochar VOCs adsorbent was prepared. Compared with the prior art, the present invention has the following advantages: (1) the process is simple to operate, has high repeatability, is environmentally friendly, and simultaneously realizes the utilization of pomelo peel waste; (2) the process adopts magnesium acetate In situ modification of biochar, the mixing method of the two breaks the conventional grinding and mixing in the prior art, and greatly improves the uniformity of the mixing of the two; (3) The obtained adsorbent has an ultra-high ratio The surface area and pore volume have super strong adsorption capacity and reversible desorption behavior for acetic acid and benzene, which also greatly reduces its adsorption heat, and has excellent selectivity for the adsorption of acetic acid/benzene. |
