Quantitative Analysis of High Temperature Toxic Metal Sorption Rates Using Aerosol Fractionation

Chemical Characterizations of PM10 Profiles for Major Emission Sources in Xining, Northwestern China

“…This could be attributed to different components and combustion temperatures for coal and petroleum products. These metals may vaporize at the high temperature and return to the solid phase as temperature decreases (Davis and Wendt, 2000). The average OC/TC ratio was 0.55 (range 0.46 to 0.62), which is similar to that found in northwestern Colorado (0.56) by , but lower than that in the soil dust profile, consistent with the 160-times abundance of EC in the coal-fired source relative to SD.…”

Emission control of sodium compounds and their formation mechanisms during coal combustion

“…Kaolin is well known as one of the good sorbent to chemically absorb sodium compounds at high temperature [24,35]. However, the absorption tests of kaolin under the coal combustion conditions have not always been reported yet.…”

“…The fine particulates formation [5][6][7][8][9][10][11][12][13][14][15][16][17], behavior of alkali metal compounds [18][19][20][21][22][23][24][25][26][27] and control technologies of semi-volatile metals [25,[27][28][29][30][31][32][33][34][35][36][37][38][39] during combustion have been studied for the last three decades. Injection of mineral powders is one of the important control technologies to capture the volatile and semi-volatile metal compounds.…”

Isolation of Metals from Liquid Wastes: Reactive Scavenging in Turbulent Thermal Reactors

“…The sorption of cesium or strontium by dispersed sorbent was quantified using the aerosol fractionation method described previously (38,45,49). Extractive samples were taken using an isokinetic aerosol sampling system described elsewhere (48 to concerns of damage to the SMPS from cesium hydroxide, which is highly corrosive, the SMPS was not used in further tests with kaolinite injection.…”

“…Kaolinite, a natural mineral composed of silica and alumina (Al 2 O 3 ·2SiO 2 ·2H 2 O), has been shown to be an effective sorbent for the high temperature capture of vapor-phase lead, cadmium, and sodium (32,33,34,35,36,37,38,39). Kaolinite also has the advantages that it is compatible with subsequent vitrification and cement processes.…”
