Process for Hydrogen Production from Sodium Sulfite Solutions Resulting from Capture of SO2 from Coal Flue Gas
Green Car Congress
JUNE 3, 2010
A typical example is the use of a dilute aqueous sodium hydroxide (NaOH) solution to absorb SO 2 from flue gas, forming an aqueous Na 2 SO 3 solution. Alternatively, oxidation of an aqueous Na 2 SO 3 solution can be carried out for the production of high purity clean hydrogen fuel. under illumination from a low pressure mercury lamp.
