Abstract

Описывается способ каталитического газофазного окисления этилена содержащим молекулярный кислород газом в однокамерном реакторе, содержащем множество реакционных труб, содержащих нанесенный на носитель серебряный катализатор и окруженных текучим теплоносителем, который входит в реактор в жидкой форме, а выходит из реактора в форме пара, отличающийся тем, что от 5 до 100 мас.% жидкого текучего теплоносителя вводят в реактор в его нижнюю часть при температуре, которая по меньшей мере на 20°C ниже температуры текучего теплоносителя на выходе из реактора.Международная заявка была опубликована вместе с отчетом о международном поиске.
