The invention relates to a novel catalytic distillation device. In the novel catalytic distillation device, the upper part is a rectifying section, the middle part is a reacting section, and the lower part is a stripping section. The novel catalytic distillation device is characterized by comprising the following parts: the reacting section comprises 8 or more than 8 overlapped catalyst beds; the upper part of each catalyst bed is provided with a fractionating tray, the middle part of each fractionating tray is provided with a downcomer, the lower end of each downcomer is provided with a liquid seal trough, a liquid distributor is arranged between a part below each liquid seal trough and the corresponding catalyst bed, and airlift pipes are arranged on both sides of the catalyst beds; a catalyst layer, an inert filler layer, a silk screen, a stainless steel porous sieve plate and a catalyst support frame are arranged on the upper part of each catalyst bed in sequence, and catalyst bed walls are arranged in th
