Process for the production of metal oxide aerosols

A process for producing a metal-oxide aerosol comprises vaporizing the elemental metal eg Ca or Mg in an oxidant free environment under controlled conditions and thereafter oxidizing said vaporized metal under controlled conditions to form an aerosol of said metal-oxide in a carrier gas stream. The...

Beschreibung
Zusammenfassung:	A process for producing a metal-oxide aerosol comprises vaporizing the elemental metal eg Ca or Mg in an oxidant free environment under controlled conditions and thereafter oxidizing said vaporized metal under controlled conditions to form an aerosol of said metal-oxide in a carrier gas stream. The aerosol may thereafter be fed to an effluent-containing gaseous stream for removal of effluents by sorption under controlled temperature conditions. Acid gas such as SO2, SO3, NO, NO2, H2S and HCl may be removed from off gases using the aerosol sorbent. PROCEDIMIENTO PARA PRODUCIR AEROSOLES DE OXIDOS METALICOS PARA EL CONTROL DE EMISIONES DE COMBUSTIBLES. EL PROCEDIMIENTO COMPRENDE VAPORIZAR EL METAL ELEMENTAL EN UN AMBIENTE EXENTO DE OXIDANTES EN CONDICIONES CONTROLADAS Y, DESPUES DE ELLO, OXIDAR DICHO METAL VAPORIZADO EN CONDICIONES CONTROLADAS PARA FORMAR UN AEROSOL DE DICHO OXIDO METALICO EN UNA CORRIENTE DE UN GAS PORTADOR. EL AEROSOL PUEDE ALIMENTARSE DESPUES A UNA CORRIENTE GASEOSA QUE CONTIENE EFLUENTES PARA LA SEPARACION DE LOS EFLUENTES EN CONDICIONES DE TEMPERATURA CONTROLADA.
