Project Description

 

 

Project Description:

The objective of this project is to develop a simple; inexpensive process to separate CO2 as an essentially pure stream from a fossil fuel combustion system using a regenerable sodium-based sorbent.

Project Accomplishments:

[NOTE: Updated information not available beginning 2004]

01-Mar-02:
Accomplishment: Multi-Cycle Sorbent Activity Indicated                                                              
Description: Conducted bench-scale, fluidized-bed multi-cycle tests of selected sodium- and potassium-based sorbents.  These tests indicated that the sorbents could maintain their activity through five cycles of carbonation (CO2 capture) and regeneration.

01-May-02:
Accomplishment: Cyclical Sorbent Regeneration Demonstrated                                                         
Description: Demonstrated (on a micro-scale) that sodium bicarbonate sorbent can be cyclically regenerated using a carbon dioxide/water vapor stream.  Regeneration with wet CO2 is a key piece of the conceptual process design, in which the final product stream destined for sequestration will contain only CO2 and water vapor

01-Jul-02:
Accomplishment: Attrition-Resistant Supported Sorbent Prepared                                                     
Description: Prepared, by spray drying, an attrition resistant, potassium carbonate-based, supported sorbent.  Materials characterization tests showed that this sorbent is suitable for use in a transport reactor (a likely reactor design for the commercial embodiment of the Dry Carbonate process).

01-Aug-02:
Accomplishment: Expimental Results Confirm Intermediate Compound Salt Formation                                    
Description: Experimental studies confirmed the theoretical prediction that an intermediate compound salt (between carbonate and bicarbonate) will be the carbonation reaction endpoint under anticipated processing schemes
