| 发明名称 | Modified trass and process for its preparation | ||
| 摘要 | Modified Trass material has an enlarged active surface compared to native Trass. A method of preparation of the Modified Trass includes contacting Trass with an agent capable to dissolve away components in the Trass, and removing the dissolved components from the Trass. The modified Tass can be used for removing substances from fluids, in particular from exhaust gases of combustion plants. | ||

| 主权项 | 1. A modified Trass having an active surface according to the Brunauer-Emmett-Teller (BET) method of ≧about 40 m2/g, obtained by a method comprising the steps of: (a) contacting Trass with a water/surfactant mixture to dissolve away components in the Trass and excavating the surface area; and (b) removing the dissolved components from the Trass to obtain the modified Trass. | ||
