The development of inert additive-doped CaO-based CO 2 adsorbents is a promising method to obtain efficient CO 2 adsorbents, while multiple programs are frequently involved, the organic solvent is often used, and CO 2 is sometimes released in the process of preparation. In this study, we first report that inert additive-doped CaO-based adsorbents can be synthesized …

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...

In fact, the particle size distribution of BN was measured by the SEM images and was in between 5 ␮m and 10 ␮m. Nano-BN was produced by the mechanical activation (MA) process without any catalyst using a planetary mill (Fritsch, Pulverisette 6). Milling balls used in the experiments were made of zirconia (ZrO2 ); its diameter was 4 mm.
