Performance and Properties of a Solid Amine Sorbent for Carbon Dioxide Removal in Space Life Support Applications

Satyapal, Sunita, Filburn, Tom, Trela, John, Strange, Jeremy·2001·Energy & Fuels

Abstract

NASA is currently using a solid amine sorbent known as HSC + for regeneratively removing CO 2 in space shuttle applications. This sorbent may also be of value for CO 2 removal in various industrial processes such as greenhouse gas control, industrial syntheses, and natural gas purification. To design novel sorbents and to design a CO 2 scrubber based on HSC +, physical and thermochemical property data are required. In this paper, we present a detailed experimental investigation of property data and long-term performance results using HSC + as a CO 2 sorbent. Differential scanning calorimetry was used to determine the heat capacity of the material. Cyclic and equilibrium capacities of the material for CO 2 pickup were determined and long-term test data show excellent performance. In addition, we have determined the heat of adsorption associated with CO 2 pickup by HSC + and the effect of moisture, using isothermal flow calorimetry. We have also performed thermal gravimetric analyses on the materials to gain insight into the stability of the material and determine the temperatures at which CO 2 and constituents of HSC + leave the surface of the material.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
