Abstract

При производстве оксида алюминия из гидроксида алюминия указанный гидроксид алюминия кальцинируют в реакторе с псевдосжиженным слоем с использованием предварительного нагревания, по меньшей мере, в одной ступени предварительного нагревания, и затем направляют, по меньшей мере, в один охладитель с псевдосжиженным слоем, в котором кальцинированные твердые частицы материала охлаждают с помощью псевдосжижающего воздуха, при этом псевдосжижающий воздух отводят из охладителя и вводят в реактор с псевдосжиженным слоем как вторичный воздух. Для того, чтобы при работе установки с частичной нагрузкой минимизировать удельное потребление энергии, поток вторичного воздуха разделяют, и байпасный поток направляют в обход реактора с псевдосжиженным слоем и вводят в трубопровод для подачи твердых частиц.
