Abstract

"CONTROLE DA POLUIçãO DO AR". A presente invenção refere-se a um gás de combustão que é passado através de uma pasta de um sulfeto de metal alcalino-terroso e a um tampão de oxirredução (por exemplo, um fosfato), preferivelmente em combinação com um carbonato e/ou hidróxido de metal alcalino-ferroso, em um método de controlar a poluição do ar. Uma composição para remover um metal pesado de um gás de combustão também é fornecido, como uma dispersão ou pasta fluida aquosa em aerossol de um sulfeto de metal alcalino-terroso e um agente de tamponamento. Um resíduo sólido do processo de controle da poluição do ar também é descrito.
