Process for the production of chlorine from hydrogen chloride

摘要

The novel feature in Cl2 prodn. by alternatingly (a) loading a catalyst with HCl at 300-420 (pref. 360-410) degrees C and then (b) regenerating the catalyst with an O2-contg. gas at 370-460 (pref. 380-420) degrees C is that the catalyst is a sintered shape made of (by wt.): (i) 2-30% oxides and/or chlorides of Cu, Fe, Ru, Ce, Bi, Ni, Co, Ga and/or Nd; (ii) 0-30% Li-, Na-, K- and/or Zn-chloride; and (iii) 98-40% ceramic-, silicate- and/or glass-carrier. This catalyst is prepd. using inorganic metal powder and/or an active component, together with a specified polymer (mixt.) and a dispersant.
