Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a quick start-up method for a reactor and a reactor system. SOLUTION: In a multitubular reactor where a heat medium having a solidifying point of 50-250 deg.C is circulated through fluid outside a tube, gas having a temperature of 100-400 deg.C is introduced into the inside of a reaction tube to raise the temperature of the heat medium, and then the heated heat medium is circulated through the fluid outside the tube. By introducing the heated gas to the reaction tube beforehand, the resolidification of the heat medium after its circulation can be prevented, which realizes quick start-up. |
