Plate type reactor, manufacturing method therefor, and reaction product manufacturing method using the plate type reactor

Abstract

In a plate type reactor, there are provided a technique for preventing the runaway of a reaction in the manufacture of a reaction product and for manufacturing the reaction product in a high productivity, a technique for filling the clearance between adjoining heat transfer plates in the plate type reactor, at least ho ogeneously and easily with a catalyst, and a method for suppressing the pressure loss, the occurrence of a hot spot and the loss of the catalyst even in the run under a high-load condition, thereby to manufacture the reaction product in a high efficiency in the plate type reactor. The reaction product is manufactured by arranging the heat transfer plates of the plate type reactor within a specified range of errors from a designed value, by arranging a plurality of partitions for forming a plurality of compartments in the clearances between the heat transfer plates and along the flow direction of a reaction material, by further arranging a plurality of vent plugs for plugging the bottom portions of the individual partitions removably, and by using a specific reaction material under the condition of a specific quantity of load.

Description

technical field [0001] The present invention relates to a plate reactor used for an exothermic or endothermic reaction involving the use of a catalyst, a method for producing the same, and a method for producing a reaction product by gas-phase contact reaction using the plate reactor. [0002] In addition, the present invention relates to a plate reactor and a method for producing a reaction product by supplying a reaction raw material to a plate reactor filled with a catalyst and reacting the reaction raw material. Background technique [0003] As a reactor used in a gas-phase contact reaction in which a gaseous raw material is reacted in the presence of a solid catalyst to obtain a gaseous reaction product, for example, a multi-tubular reactor in which a catalyst is filled in a reaction tube in a reaction vessel is known. (For example, refer to Patent Document 1) and a plate reactor in which a catalyst is filled in gaps between two or more heat transfer plates in a reactio...

AI Technical Summary

Problems solved by technology

However, there are the following disadvantages: since the reaction tube used in the multi-tubular reactor is a tube with a radius of 20 to 30 mm, and the tube from the inlet to the outlet of the reaction fluid (the general term for the reaction raw material mixture, the reaction product mixture, etc.) is used Therefore, under the condition that the processing load per unit catalyst of the reaction fluid is high, the pressure loss of the reaction fluid is large, the pressure in the reactor rises, and as a result, the yield of the target reaction product decreases.

[0018] In the above-mentioned proposals, although the structure of the plate reactor and its application in the contact gas phase oxidation reaction are described, there is no method for properly controlling the heat generated by the reaction to prevent hot spots and improve the yield of the target reaction product. any mention
