Horizontal type fixed bed reactor for producing propene with oxygen-containing compound as raw material

Abstract

The invention provides a horizontal-type fixed bed reactor which is used for producing propylene with oxygen-containing compound as the raw material. The reactor comprises a casing, a raw material inlet is arranged at one transverse end of the casing, a product outlet is arranged at the other end, a porous separating part is arranged inside the casing, and separates the internal space of the casing into at least four transverse areas, two of the areas which are positioned at the ends of the casing are respectively communicated with the raw material inlet and the product outlet, and other areas are a reaction area and a cooling area which are arranged at intervals; a cooling fluid inlet is arranged on the casing corresponding to the cooling area. The horizontal-type fixed bed reactor has the advantages that the structure is simple, the design, the manufacture and the maintenance of the equipment are easy, the operation is convenient, the reaction is easy to control, and good reaction condition is easy to maintain.

Description

technical field [0001] The invention relates to a propylene production equipment, in particular to a horizontal fixed-bed reactor for producing propylene with oxygen-containing compounds as raw materials. Background technique [0002] Oxygenated propylene technology is a process for producing propylene from non-petroleum resources, which has great application prospects. According to numerous published literature reports, the production of propylene from oxygen-containing compounds is a strongly exothermic reaction type, and the selectivity of the target product propylene is relatively sensitive to temperature. [0003] Among the relatively mature technologies for producing propylene from oxygenates in the world, the MTO process jointly developed by UOP / Hydro uses a fluidized bed reactor, which has better heat transfer effect and is easier to control the reaction temperature. Therefore, the requirements for the wear resistance of the catalyst are relatively high; Lurgi’s MTP...

AI Technical Summary

Problems solved by technology

[0009] The invention provides a horizontal fixed-bed reactor for producing propylene by using oxygen-containing compounds as raw materials. The reactor has a simple structure and can solve the problem that the selectivity of propylene decreases due to the increase of the temperature of the raw material due to the exothermic reaction.
