Abstract

Настоящее изобретение относится к способу транспортировки мелкозернистых твердых частиц в реакторе с псевдоожиженным слоем, а также к соответствующей установке. Предлагается вводить первый газ или же газовую смесь снизу через центральную трубу (3) в смесительную камеру (7) реактора (1), причем эта центральная труба (3), по меньшей мере, частично окружена неподвижным кольцевым слоем (10) псевдоожиженного материала, который приводится в псевдоожиженное состояние посредством подачи псевдоожижающего газа. Скорости движения потоков первого газа или же газовой смеси, а также псевдоожижающего газа для создания кольцевого слоя (10) псевдоожиженного материала регулируются таким образом, чтобы значения числа Фруда для частиц в центральной трубе (3), находились в пределах от 1 до 100, в кольцевом слое (10) псевдоожиженного материала - в пределах от 0,02 до 2, а в смесительной камере (7) - в пределах от 0,3 до 30.Международная заявка была опубликована вместе с отчетом о международном поиске.
