<p>A new absorbent for water vapor is disclosed which is non-oxidizing and is suitable for use as the absorption working pair in combination with H2O in absorption heat pumps, and also as a liquid drying agent. The absorbent is comprised of a mixture of at least two alkali metal thiocyanates, preferably KCNS and NaCNS. The preferred weight ratio is between 2 and 4, which remains liquid at all water vapor pressures above 1/16 ATA (curve ''30 Na'' on the Figure). Further advantages are obtainable by incorporating at least one of lithium cations, cesium cations, and hydroxide anions in the absorbent mixture.</p> |
