Multi-purpose dehydrogenation reaction device

Abstract

Multi-purpose dehydrogenation reaction device, including a top cover, a reactant inlet is set in the middle of the top cover, an upper head and a lower head at the bottom are respectively arranged on both sides under the top cover, and the upper head and the lower head are fixedly connected by a cylinder joint The upper and lower ends of the cylinder section are respectively provided with through holes, and a wire mesh demister is arranged between the upper through holes, and a steam input pipe is arranged above the wire mesh demister; the through hole and the wire mesh demister are arranged The upper gas riser is connected; a catalyst bed is set between the lower ends of the barrel; the gas to be dehydrogenated enters the reactor from the reactant inlet, and is fully mixed with the water vapor input from the steam input pipe, reducing the partial pressure of the reactant. When the mixture of reactants and water vapor enters the wire mesh demister downwards, the wire mesh demister separates the gas and liquid, the liquid enters the cylinder section, and the gas enters the reaction zone where the ceramic balls support the catalyst. After the dehydrogenation reaction The product flows out from the outlet; the invention has the characteristics of low cost and simple structure.

Description

technical field [0001] The invention relates to the technical field of dehydrogenation reactors, in particular to a multipurpose dehydrogenation reaction device. Background technique [0002] With the continuous progress and development of science and technology, more and more new materials have entered and changed our lives. The birth of new materials also plays an important role in the reaction and processing equipment. Dehydrogenation reactions play an increasingly important role in the processing of many materials. Take styrene as an example. Styrene is used as a raw material for resins, plastics, and elastomers, and the most important and critical step in the processing of styrene is the dehydrogenation reaction. At present, all dehydrogenation reactions are carried out in dehydrogenation reactors. [0003] The dehydrogenation reactors currently on the market are complex in structure and high in cost, and can only dehydrogenate organic matter in one state, failing to...
