Abstract

Equipment for mixed phase reaction distillation, particularly equipment for mixed phase reaction distillation to produce MTBE. The equipment comprises a rectifying section I at the upper part, a reaction section II at the middle part, and a stripping section III at the lower part. The reaction section II comprises a plurality of superposed catalyst beds which are connected by at least one catalyst flow pipe disposed between each pair of adjacent catalyst beds, and a sealed cover at the top above the uppermost catalyst bed of the plurality of catalyst beds. The reaction section II further comprises at least one vapor passageway disposed at one side of the reaction section II, and at least one liquid passageway disposed at the other side of the reaction section II. The reaction section II also includes one feed inlet disposed between the uppermost catalyst bed and the sealed cover for introducing preheated feed and one feed inlet disposed between each pair of adjacent catalyst beds of the plurality of catalyst beds for introducing unpreheated feed. The equipment may further comprise another reaction section above a lower reaction section.
