Title:
METHOD OF VAPOR PHASE CATALYTIC OXIDATION USING MULTITUBULAR REACTOR
Document Type and Number:
WIPO Patent Application WO/2004/018403
Kind Code:
A1
Abstract:
A method of vapor phase catalytic oxidation that is capable of effectively removing heat of reaction, preventing occurrence of hot spots and efficiently obtaining a desired product. In particular, a method of performing a vapor phase catalytic oxidation of substance to be oxidized with a gas containing molecular oxygen by means of a multitubular reactor, the multitubular reactor comprising a cylindrical reactor shell fitted with a raw material supply port and a product outlet; multiple circular conduits disposed around the cylindrical reactor shell and used to introduce heat medium into the cylindrical reactor shell or to lead heat medium out therefrom; a circulation device for connecting the multiple circular conduits to each other; multiple reaction tubes restrained by means of multiple tube plates of the reactor and having a catalyst accommodated therein; and multiple baffles arranged in the longitudinal direction of the reaction tube and used to change the direction of heat medium introduced in the reactor shell. In this method, the vapor phase catalytic oxidation is carried out under such conditions that the heat transfer coefficient of heat medium is 1000 W/(m2·K) or higher.
