GAT-O-SORB — A Regenerable Sorbent for Carbon Dioxide Control 670844
A regenerable absorbent in solid granular form has been developed for the removal of carbon dioxide from air or other gases. The unique features of the absorbent are: (a) no pre-drying of the gas stream is necessary prior to carbon dioxide absorption, and (b) only moderate regeneration conditions are necessary to desorb CO2, for example, heating to 180 F and evacuating to a 40 mm vacuum.
An operating laboratory prototype having a four-man capacity was built and tested, continuously removing 0.41 lb/hr of carbon dioxide at a 7.6 mm CO2 partial pressure.
The system penalties for the unoptimized prototype were:
1.
Absorbent weight - 30 lb (7.5 lb/man)
2.
Structure and controls - 63 lb (total: 93 lb, or 23.3 lb/man)
3.
Electrical power - 288 w (thermal power(electrical or sensible), 472 w; total 760 w, or 190 w/man)
4.
Envelope volume - 14 × 24 × 33 in.
The absorbent, called GAT-O-SORB,* was devised and developed under an independent research program, and improved under contract NAS1-2915 for development of the laboratory prototype model. The design and performance of the cycling two-bed system are described. A comparison is shown between GAT-O-SORB and synthetic zeolite for carbon dioxide removal.
