Title: "Kellogg" technology for chlorine
Post by: Stephen Ferro on May 12, 2006, 06:27:08 AM

Hi!

Can anybody help me where can I find some information about "Kellogg" technology for chlorine to be used in direct chlorination.
I'm only interested in that is there any references (mean plants or something)for the next:
HCl+O2= Cl2+ H2O
Does anyone use this reaction for producing high purity Cl2?

Thnx in advance.
Stephen

The purest Cl2 can be obtained by electrolysis

Stephen Ferro:

The reaction you asked about is known as the Deacon reaction:

4HCl + O₂ ==> 2Cl₂ + 2H₂O

The reaction takes place at about 400 to 450 °C in the presence of a copper chloride (CuCl₂) catalyst. Three companies developed commercial processes based on the Deacon reaction:

• The Kel-Chlor process developed by the M.W. Kellogg Company in the USA
• The Shell-Chlor process developed by the Shell Oil Company in the Netherlands
• The MT-Chlor process developed by the Mitsui Toatsu Company in Japan

The Deacon processes are outdated technology. Most chlorine today is produced using electrolytic processes.
