摘要:

以膨胀硫化石墨为基质,制备了新型氯化铵/氯化钙/氯化锰/膨胀硫化石墨复合吸附剂,并测试了其在非平衡条件下的吸附/解吸特性。在与3种单盐各自的Clapeyron反应平衡曲线的比较中发现,该多盐复合吸附剂同时具备这3种单盐的特性,却存在一定的差异。在非平衡条件下的吸附/解吸特性曲线测试过程中发现,该多盐复合吸附剂具备这3种金属氯化物各自的一些性质,却不存在金属氯化物-氨络合过程中普遍存在的吸附滞后现象。在实验的基础上计算和比较了使用不同吸附剂的单级间歇式吸附制冷循环的COP和SCP。结果证明多盐复合吸附剂的性能优于单盐吸附剂。

Abstract:

A new type of consolidated composite sorbent for NH4Cl/CaCl2/MnCl2 is developed by the mixture of ENG-TSA (expanded natural graphite treated by the sulfuric acid),and its sorption/desorption process is tested under non-equilibrium conditions.Compared with the theoretical Clapeyron curves under equilibrium conditions of three kinds of salt,the consolidated composite sorbent shows combining properties of three salts but there are also some differences.The consolidated composite sorbent shows some properties of the three metal chlorides respectively during the sorption/desorption experiments under non-equilibrium conditions.However,there is almost no sorption hysteresis which is prevalent in single salt-ammonia complexing process.On this basis,the COP and SCP of a single-stage sorption refrigeration cycle using the composite sorbent is calculated.The experiments prove that the performance of the consolidated composite multi-salt sorbent is better than single salt sorbents.

Key words: consolidated composite sorbent, non-equilibrium, chemisorption, ammonia, refrigeration
