Claims17
A process for producing hydrogen and chlorine from hydrogen chloride which comprises the steps of:
- (i) generating a plasma by the use of a radio-frequency plasma generating means;
- (ii) introducing HCl, accompanied by an inert non-oxygenated plasma-forming gas, into said plasma wherein said HCl is heated to a temperature in the range between 2000 degrees K and 6000 degrees K to convert at least a portion of the HCl into its constituents;
- (iii) cooling the constituents to form a gas product mixture comprising H.sub.2 and Cl.sub.2 ;
- and
- (iv) recovering said gas product mixture.
