Selection of additives of spraying secondary refrigerant in ice slurry preparation;

In which first introduced the significance of the refrigeration unit’s utilization in the low temperature building-up reactions in chemistry drugs manufacture, next introduced how selected the refrigerant and the secondary refrigerant and through the entire refrigeration system heat transfer energy graduated arm calculation determined the refrigeration compressor, the condenser and .

Calculates and analyzes the evaporator and the evaporative condenser of a 3 kW R404A/CO_2 refrigeration system(CO_2 as a low temperature secondary refrigerant).

Research shows supported reagents have the highest activity with 4 mmol/g loading of ZnCl\-2, 150 ℃ calcined temperature and 5 h activity and the active sites of catalysts are not crystalline ZnCl\-2 but isolated ZnCl\-2.

An introduction is being presented to the basic concept of CLC,together with a brief analysis of its main features and a detailed review concerning the research status of oxygen carriers(OC),which play an important role in CLC combustion,as well as a description of relevant system designing and performance tests.

The basic concept and some characteristic of CLC are introduced, the metal oxygen carrier (OC) which are very critical in CLC system are analyzed detailedly, and the reactor development of CLC system and thermodynamic performance analysis of CLC system with other existing power cycles are described.
