Abstract

Предложен реактор для проведения высокоэкзотермической реакции между жидкостями, такими как пероксид водорода и пропилен. Реактор состоят из последовательности отдельных зон, содержащих насадочный слой твердого катализатора. Жидкость, отводимая из каждой зоны, подвергается охлаждению, причем основная часть жидкости возвращается обратно в ту же зону, а неосновная часть проходит на соседнюю последующую зону.
