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

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
