    摘要： Described is a filter-drier core for removing acids and halides that are generated by decomposition of a refrigerant that contains a fluoroiodocarbon, the filter drier core comprising a molded core that includes gamma phase activated alumina and a molecular sieve. The molecular sieve has a pore size between 3-4 angstroms and between 300-00 m2/g surface area, and/or the alumina is provided in a beaded form with average bead diameter between 0.1-10 mm. An alumina surface area may be between 140-250 m2/g, and an average pore size may be 6 nm to 16 nm. A percent molecular sieve in the core may be between 0-40%, with the rest of the core being alumina. To increase surface area of the core, the filter-drier core may define a plurality of suitably shaped channels that extend longitudinally through the core, may have fins that extend from a central body, or may be configured as a plurality of rods. A refrigerant system includes a refrigerant circuit through which a refrigerant flows, and a filter-drier unit including the filter-drier core configured for contact with the refrigerant for removing contaminants from the refrigeration system.
