| 摘要 |
The present invention relates to a method of production, for example, anhydrous metal oxide from metal hydroxide, in which the metal hydroxide, at least, partially is dehydrated and heated prior to introduction thereof in a reactor with a fluidized bed in which the hydroxide metal is heated to a temperature from 650 to about 1250°C at the expense of fuel burning, thus producing the metal oxide, wherein primary air and/or oxygen-enriched secondary air are fed to the reactor with the fluidized bed. For providing rather low dust emission and insignificant grain separation the oxygen or oxygen-enriched gas are supplied to the reactor with the fluidized bed at a low rate. |
