Alstom’s Limestone Chemical Looping Concept• In Alstom’s process, calcium
compounds from limestone are used as the reactant
• Coal is indirectly combusted or gasified by hot oxygen carrying reactant
• The Reactant is not consumed and is alternately reduced (oxygen removed) and oxidized (oxygen replenished) as it cycles between reactors
• The Reactant also carries heat where needed

Chemical Looping - CFMSummary
• CFM validated the Prototype’s solids transport concept
• Multi-loop CFM operation was demonstrated: start-up and shutdowncontrol stability of the system
• Data used to verify the scale-up method
• CFM used for the training of operators for the prototype unit
• CFM will be used to trouble shoot Prototype solids transport

Prototype Progress To Date
The Prototype project has made significant progress toward achieving fully integrated operation.
• Controlled solids recirculation in the cold flow model and the prototype.
• Online heat-up of the process by external electric heaters, external natural gas burners and direct injection of natural gas into the reactors.
• Coal firing at relatively low reactor temperatures with low tar formation.
• Coal firing at design temperature with no evidence of tar formation.
• Coal and sorbent feeding online.
• SAHE operation.
• Hot restart after main fuel trip.
• Production of CO2 (Option 1) and Syngas (Option 2).
• Combustion reactions with chemical looping reactions.
Chemical looping reactions were achieved on June 11, 2011

Chemical looping reactions were achieved on June 11, 2011
• Point “A” - 360 lb/hr of coal and 1900 lb/hr of air for solids transport were flowing to the reducer
• Point “A” to Point “B” - CO2 concentration is about 35% vol.
• Point “C” - The recycle intake was switched from air to recycled product gas. The CO2 slowly rises as N2 is washed out of the system
