The Adsorbent Size Effect on the Mercury Capture by In situ Generated Titania |
| 초록 |
Titania particles are prepared by gas phase reaction through the quartz reactor. The characteristics of titania particles prepared by different conditions is analyzed by transmission electron microscopy (TEM) and x-ray diffraction (XRD). The geometric mean particle diameter (dSubg) is measured by scanning mobility particle sizer (SMPS) with nano-differential mobility analyzer (nano-DMA). TEM image analysis is to evaluate the properties of agglomerates, such as fractal dimension (DSubf), primary particle size, and the radius of gyration (RSubg). Experiments were performed to investigate the mercury removal efficiencies for primary furnace temperature (500-1000 SupoC). Titania particles in the presence of UV irradiation chemisorbed mercury on titania surface area. With increasing in primary furnace temperature, the mercury capture efficiencies are increased from 7.6 to 77.6%. This is probably because with increasing in primary furnace temperature, the structure of titania particles is more opened, and the effective surface area is increased. |
