Hydrogen fuel cell powers beneficial SO2 conversion

Lackner Process

Lackner Process

Klaus S. Lackner and Tim A. Rappold both from New York have received a patent (US 7,799,310) on a process for the conversion of SO2 in to sulfuric acid and hydrogen that later utilizes the hydrogen in a fuel cell reaction that returns energy to the sulfuric acid reaction.  The specification discusses the process as being used for the purpose of disposal of sulfur rich waste, the accumulation of which is discussed as being a looming problem.  Potential additional applications may include the use of the invention in the power industry as a potential replacement substitute for the contact process.  The Trustees of Columbia University in the City of New York are listed as the assignee.
