Mechanochemistry is very attractive as an efficient, solventfree, and simplified technique for the preparation of composite adsorbents. Here, a series of polyethyleneimine (PEI)modified SiO2 adsorbents were prepared via mechanical ball milling for selective adsorption of CO2 at high temperatures. The structural properties of these adsorbents were characterized by XRD, SEM, TGA, FTIR, and N2 ...

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sandlime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
