Claims (1)
- Способ существенного уменьшения или полного удаления сульфата аммония, образующегося при производстве акрилонитрила при прямом окислительном аммонолизе пропилена/пропана, аммиаком и кислородсодержащим газом (например, воздухом) в псевдоожиженном слое катализатора, усовершенствование в нем заключается во введении органического соединения/ий/ в реактор в точке, где соединение(я) реагируют практически со всем избыточным аммиаком без воздействия на выход акрилонитрила. Предпочтительно в реактор вводить метанол при температуре ниже температуры его коксования. В частности, когда используют катализатор псевдоожиженного слоя, работающий при низком содержании кислорода, в реактор вводят дополнительное количество кислородсодержащего газа на расстоянии приблизительно от 8 до 14 дюймов от места ввода метанола.
