Abstract

Настоящее изобретение относится к способу производства, например, безводного оксида металла из гидроксида металла, в котором гидроксид металла, по меньшей мере частично, обезвоживают и подогревают перед вводом в реактор с псевдоожиженным слоем, в котором гидроксид металла нагревают до температуры в интервале приблизительно от 650 до приблизительно 1250°С за счет сжигания топлива, и в результате образуется оксид металла, при этом в реактор с псевдоожиженным слоем подают первичный воздух и/или вторичный воздух, который обогащен кислородом. Для обеспечения весьма низких выбросов пыли и незначительного разрушения зерен кислород или обогащенный кислородом газ вводят в реактор с псевдоожиженным слоем с низкой скоростью.
