Green production of a novel sorbent from kaolin for capturing gaseous PbCl2 in a furnace

The pollution of semi-volatile heavy metals is one the key environmental risks for municipal solid waste incineration, and in-situ adsorption within furnace by mineral sorbents such as kaolin has been demonstrated a promising emission control method. To lessen consumption sorbent, novel material amorphous silicate was produced from through pressurised hydrothermal treatment. Its performance gaseous PbCl2 capture tested in fixed bed compared with unmodified metakaolin. With increasing temperature, rates all declined due to higher saturated vapour pressure, while partitions residual form lead increased which indicated stability sorbent because melting effect. new larger surface area reformed structure presented 26% more efficiency than raw at 900 °C, modification pressure improved these properties. Additionally, production this high-temperature relatively inexpensive, required little thermal energy no chemicals produce effluent generated, thus being much cleaner other methods.
