Abstract
A process for producing chlorine by oxidizing hydrogen chloride with oxygen in the presence of a supported ruthenium oxide catalyst or a ruthenium mixed oxide catalyst. The content of ruthenium oxide is from 0.1 to 20% by weight and the ruthenium oxide has a mean particle diameter of from 1.0 to 10.0 nm.
Claims21
