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 m.sup.2/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 m.sup.2/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.

A preparation method for a nanopore starch-based adsorbent. The method mainly comprises: constructing a large number of lamellar crystals on surfaces of starch granules, and inducing the formation of a nano-scale pore channel structure by means of the lamellar crystals. A large number of control tests have proved that the flaky crystals have direct influence on the formation of the nano-scale pore channel structure. The construction of a pore channel structure in a starch matrix material greatly increases the specific surface area, and improves the adsorption properties. In addition, the method is beneficial to the introduction of functional particles (magnetic particles), and avoids the problem of pore channel blockage due to first forming pores and then introducing functional particles.
