Decompose when roasting and produce CO2, CO2The space that effusion produces increases the internal gutter of granule, thus increases adsorbent
Surface area, improves absorbability.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.
1) each component is weighed by proportioning.
2) component A is prepared:
The most zeolite-loaded TiO2Preparation: weigh nano-TiO25g, the present embodiment uses Degussa nanometer P25, is dissolved in
In 500ml aqueous solution containing dodecylbenzene sodium sulfonate 0.025g, under 300rpm, ultrasonic agitation 1 hour, is dipped into
In the natural zeolite of 1000g, stirring 1 hour, 105 DEG C are dried 2 hours, 300 DEG C of roastings 2 hours, are ground into 80
Purpose powder body, i.e. prepares zeolite-loaded TiO2。
The most activated carbon supported TiO2Preparation: weigh nano-TiO22.5g, the present embodiment uses Degussa nanometer P25,
