Hydrogenation reactor temperature control system and method

Abstract

The embodiment of the invention discloses a hydrogenation reactor temperature control system and method. The system comprises a hydrogenation reactor, a heat storage container and a controller, wherein a temperature control jacket is arranged on the outer surface of the hydrogenation reactor, and a heat storage material is stored in the heat storage container; the controller is used for controlling the start and stop of circulation of the temperature control medium between the temperature control jacket and the heat storage container by controlling the bypass valve so as to adjust the temperature of the hydrogenation reactor. According to the temperature control system, heat released in hydrogenation reaction is stored by using the heat storage material, and the temperature of the hydrogenation reactor is maintained in the short-time shutdown process of the hydrogenation reactor, so that the reactor can be quickly started with low energy consumption as required, and the energy consumption of repeated starting and shutdown is reduced.

Description

technical field [0001] The present application relates to the technical field of hydrogen production, in particular to a hydrogenation reactor temperature control system and method. Background technique [0002] Hydrogen production by electrolysis of water is a relatively convenient method for producing hydrogen. Direct current is applied to an electrolytic cell filled with electrolyte, and water molecules undergo an electrochemical reaction on the electrodes to decompose into hydrogen and oxygen. Hydrogen production by electrolysis of water is a flexible, efficient and high-purity hydrogen production method, which is especially suitable for the production of hydrogen fuel for fuel cells. In the current electricity price system, the daily peak-to-valley price difference is adopted to adjust the electricity load at different times of the day, and the use of relatively cheap electricity to electrolyze water for hydrogen production during the low-load period can effectively red...
