Abstract
Описан способ производства формальдегида. Способ включает подачу в реактор питающего потока, содержащего метанол; превращение метанола в формальдегид в реакторе с использованием смешанного оксидного катализатора для получения технологического потока, содержащего формальдегид; отделение формальдегида от технологического потока для получения потока продукта, содержащего формальдегид, и потока отходящего газа; подачу по меньшей мере части потока отходящего газа в конденсатор пара для поднятия температуры по меньшей мере части потока отходящего газа для получения нагретого потока отходящего газа; и подачу нагретого потока отходящего газа в слой каталитического сжигания для каталитического сжигания компонентов нагретого потока отходящего газа с получением прошедшего дожигание потока отходящего газа.
