Embodiment Construction

[0022] As shown in Figure 1, a kind of horizontal moving bed reactor that is used to produce propylene with oxygen-containing compound as raw material, comprises a horizontal cylindrical casing 1, and the cross section of casing 1 also can be other shapes, as square , ellipse, trapezoid, etc. A raw material inlet 2 is provided at one lateral end of the housing 1 , and a product outlet 3 is provided at the other end.

[0023] Housing 1 is provided with 10 plane screens 8 horizontally arranged in parallel, and the screen 8 divides the internal space of the housing into 11 horizontally continuously arranged areas. It communicates with the product outlet 3, and the remaining 9 areas are 5 reaction areas 4 and 4 cooling areas 5, and the reaction areas 4 and cooling areas 5 are arranged at intervals. In addition to the screen 8, other partitions, such as perforated partitions, can also be used.

[0024] Because the catalyst flows continuously in the reaction zone 4, it will be wor...

Abstract

The invention discloses a horizontal reactor of moving bed type, which produces propylene with oxygenated chemicals as raw material. The reactor includes a shell. One transverse end of the shell is provided with a raw material inlet and the other end is provided with a production outlet. A polyporous separator is arranged in the shell, which separates the internal space of the shell into at least four horizontal areas. The two areas at the end part of the shell are respectively communicated with the raw material inlet and the production outlet. The rest areas are one reaction area and a cooling area with an interval arranged in the middle. The shell corresponding to the upper end and the lower end of the reaction area is respectively provided with a catalyst inlet and a catalyst outlet. The shell corresponding to the cooling area is provided with a cooling liquid inlet. The horizontal reactor of moving bed type of the invention has simple structure, easy equipment design and manufacture, easy maintenance and convenient operation. The reaction can be controlled easily and the reaction condition can be kept well.

Description

technical field [0001] The invention relates to a propylene production equipment, in particular to a horizontal moving 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 MT...
