HYDROGEN CHLORIDE OXIDATION APPARATUS AND HYDROGEN CHLORIDE OXIDATION PROCESS
摘要
<p>Disclosed is a hydrogen chloride oxidation apparatus for producing chlorine by oxidizing hydrogen chloride through a catalytic gas phase reaction in the presence of a catalyst by using hydrogen chloride and oxygen as raw materials. This hydrogen chloride oxidation apparatus is characterized by comprising a mixing portion for mixing the raw material gases, and a transfer piping for transferring the mixed raw material gases from the mixing portion to a reactor wherein the catalytic gas phase reaction is performed. This hydrogen chloride oxidation apparatus is also characterized in that a gas contact surface of the mixing portion and/or a part of a gas contact surface of the transfer piping is made of or covered with tantalum or a tantalum-tungsten alloy. Also disclosed is a hydrogen chloride oxidation process using such a hydrogen chloride oxidation apparatus.</p>
