Conversion processes carbonization

Recovery of hydrogen cyanide from coke-oven gases has been dormant in the early 1990s, but new methods involving environmental control of off-gas pollutants may be lea ding the way for a modest return to the recovery of cyanide from coke-oven gases (see Coal conversion process, carbonization). 

Shift Conversion. Byproducts such as carbon oxides that deactivate the catalysts used in the synthesis have to be removed or converted to the inert species before the actual synthesis occurs. In the shift conversion process, carbon monoxide is converted to carbon dioxide. The reaction is exothermic and reversible. 

In the shift conversion process, carbon monoxide is converted to carbon dioxide with the formation of additional hydrogen by the following reaction ...
