Product Guide HIGH SILICA ZEOLITE

OUR HISTORY Union Showa K.K. was founded as a joint venture between Showa Denko K.K. and Union Carbide in 1970. Union Showa K.K. built a new plant in Yokkaichi in Mie prefecture and began the production and sales of zeolitic adsorbents ( Molecular Sieves ) for removing impurities in chemical plants and removing moisture of refrigerants such as car air conditioners and refrigerators. Concurrently, as Japan distributor of UOP's adsorbent, we also conduct sales of alumina-based adsorbents, high-silica zeolites for exhaust gas and deodorant applications. In 2014, Union Showa K.K. acquired the license of High Silica Zeolite from UOP LLC and completed the construction of a new plant in Aizu in Fukushima prefecture and began domestic production. Hence, two-factory system capable of responding quickly to customer's requests is established. We merge our product development achievements on top of UOP's innovative technologies and offer solutions that meet individual needs of customers while highly consider energy conservation and environmental improvement. Chronology 1914 UOP founded in the United States, development and licensing business of petroleum refining process started 1949 UCC successfully synthesized A, X type zeolite for the first time in the world 1954 UCC, started construction of a synthetic zeolite manufacturing plant for commercialization under the product name of Molecular Sieve 1970 Union Showa K.K. founded as a joint venture between UCC and Showa Denko KK. Acquiring A & X type manufacturing and sales license from UCC, Construction of Yokkaichi Plant in Mie Prefecture, commence production of Pellet (cylindrical zeolite) 1974 Merged with Showa UNOX KK., a joint venture between Showa Denko and UCC, and wastewater treatment business is added. 1975 Started production of Powder (ed zeolite) at Yokkaichi Plant 1980 Started production of Beads (spherical zeolite) at Yokkaichi Plant Separate from wastewater business and revive the company name of Union Showa K.K.

1988 UCC transfers Molecular Sieve business to UOP 1995 Start selling adsorbent High Silica Zeolite 1996 Yokkaichi Plant acquired ISO 9002 2000 Start selling alumina-based adsorbent 2002 Head Office, Yokkaichi plant acquired ISO 9001 2003 Head Office, Yokkaichi Plant acquired ISO 14001 2011 Commence supply of ion-exchange adsorbent for treatment of highly contaminated water after accident at Fukushima Dai-ichi NPS 2014 Acquired manufacturing license of High Silica Zeolite from UOP, established new Aizu factory in Fukushima Prefecture

Adsorption volume (cc/100g) HIGH SILICA ZEOLITE Molecular sieves are widely used as desiccants for drying applications, but have not generally used as deodorants to adsorb odors. This is because the cavities in the molecular sieve crystals are quickly and selectively filled with water even when they are brought into contact with a small amount of moisture far less than the moisture present in the air. Hence, unable to adsorb odor molecules and other molecules. The chemical formula of molecular sieve is M 2 / n O.Al 2 O 3.xSiO 2.yH 2 O M: Metal cation n: valence When the ratio of SiO 2 in this chemical composition is increased to High Silica Zeolite, the proportion of metal cations present in the molecular sieve crystal lattice is decreased. This causes the affinity of high silica zeolite towards polar substances such as water is weakened and becomes more strongly adsorb nonpolar substance. Adsorption volume at 25 C Comparison of water and cyclohexane adsorption volume water based on SiO2/Al2O3 ratio Water Cyclohexane ratio Because of these adsorption properties, hydrophobic molecular sieve called High Silica Zeolite preferentially adsorbs Volatile Organic Compounds (VOC) and Odor components rather than moisture in the atmosphere, hence it can be utilized for VOC removal and deodorant applications.

Adsorption volume For deodorant applications, various odors can be adsorbed and removed even concentration below the perceptual range. In addition, by weakening the affinity with polar substances, moisture can be desorbed at a lower temperature than hydrophilic zeolite. In other words, moisture adsorbed at lower temperatures can be desorbed and regenerated, so it is possible to be used as adsorbent in dehumidifier or air conditioner with humidity control function.
