Multistage reactor for exothermic or endothermic chemical processes

Claim 1

A multi-stage reactor apparatus suitable for exothermic and endothermic chemical reactions between at least two reaction components which reactor comprises: (A) a closed reactor shell confining a reaction space wherein said reaction space contains a plurality of reaction stages, (B) a first inlet means for a first reaction component in direct fluid communication with said reaction space, for directing said first component solely into a first reaction stage and capable of being connected to a first reaction component source, (C) a second inlet means for a second reaction component, said second inlet means being an axially aligned conduit within said reaction space and in direct fluid communication with each of the reaction stages and capable of being connected to a second reaction component source, (D) a plurality of reaction component guiding means consisting of successive radially disposed lamellae within said space defining a zigzag path through a plurality of interconnected reaction stages through which the first reaction component steam passes in succession from said first to a final reaction stage, wherein each reactor stage consists of the portion of reaction space between three successive lamellae, wherein two lamellae of each reactor stage are attached to the reactor shell, while another lamellae is attached within said reaction space to said second inlet means, said another lamellae being situated between the aforementioned two lamellae, and adjoining the inlet of one of the reaction components, and the number of sequential reaction stages is in the range from about 10 to 25, (E) a third inlet means for a temperature moderating component in direct fluid communication with a substantial number of said interconnected reaction stages, said third inlet means being capable of being connected to a temperature moderating source, and (F) reaction mix outlet means disposed in direct fluid communication with the final reaction stage, whereby during operation of the reactor, the reaction temperature within said reaction space can be maintained relatively constant.
