Abstract

The invention relates to an electric heating plate type reactor and application thereof. The reactor comprises heating plates, reaction areas and electric heating wires, the plurality of heating plates are fixedly connected, the reaction area is arranged between every two heating plates, and the electric heating wires are mounted on each heating plate. A reaction gas inlet, a product outlet, a regeneration gas inlet and a regeneration gas outlet are respectively formed in the heating plate. The reactor is used in propane dehydrogenation reaction, the heat transfer efficiency can be greatly improved, the reaction temperature is reduced, side reactions are reduced, and energy and cost are saved.

Description

technical field [0001] The invention belongs to the field of reactor design, in particular to an electric heating plate reactor and its application. Background technique [0002] The propane dehydrogenation reaction is an endothermic reaction. The heating furnace in the traditional process is an adiabatic reactor. During the reaction process, the reaction temperature will gradually decrease due to the endothermic reaction. Therefore, in order to maintain sufficient reaction temperature at the outlet of the reactor to meet the reaction requirements, the reactor is heated to a value higher than the optimal reaction temperature by a heating furnace before entering the inlet. But high temperature is extremely unfavorable to propane dehydrogenation reaction. Not only will it aggravate the cracking reaction, lead to serious carbon deposition, affect the long-term stable operation of the device, but also cause energy waste. After a period of reaction, the reaction performance of ...
