Title:
酸素を用いた塩化水素の酸化方法
Document Type and Number:
Japanese Patent JP2009537447
Kind Code:
A
Abstract:
Procedure for carrying out an optionally catalyst-supported hydrogen chloride oxidation process in the presence of oxygen, comprises: single or multi-stage cooling of a process gas; separating the non-reacted hydrogen chloride and reaction water from the process gas, drying the product gases and separating chlorine from the mixture, where the process is carried out in a reactor whose structural components that come in contact with the reaction mixture are made of nickel or a nickel-containing alloy.
