  Activated Alumina Balls
 

Activated Alumina developed and manufactured by DESICCA CHEMICALS is of superior quality adsorbent / desiccant. Activated Alumina is manufactured by latest technology to attain the high quality properties such as Adsorption, Surface area, Pore Volume and Mechanical strength.

The main advantage of our Activated Alumina are ease of handling, non-corrosive nature, capacity for repeated regeneration, Inert towards liquid water, stability to fairly high temperature, low resistance to gas flow, great mechanical strength and can achieve low dew point of - 75C.

We do manufactures tailor made Activated Alumina for various applications to be used as Specialty Adsorbent, Catalyst / Catalyst Carrier, Bed Support etc.

DESICCA GRADE Activated Alumina is used for drying of air, gases, and liquids. Purification and conditioning of insulating oil and Industrial oils. Removal of acidic impurities and trace metal scavenging in organic streams and inorganic gases (fluoride scavenging in HF alkylation and feedstock purification). Removal of oil vapours from gases. Purification of drinking water e.g. removal of floride compounds etc. Used in refrigeration circuits, transit packing for goods like electronic pharmaceutical and food. Used as catalyst & catalyst bed support / carriers. Grade FR - I used as fire retardant fillers.

APPLICATIONS

Alumina Balls when used as bed toppings and supports will act as filters to remove many impurities from the gas stream & help in uniform distribution of the feed gas. Presence of Alumina Balls at the top & bottom of the catalyst bed, keep the bed intact during pressure fluctuation. It can withstand high thermal shocks and are unaffected by repeated emergency shutdown and startups. The Alumina refractory bed supports are specially useful as inert catalyst support in secondary reformers of ammonia manufacturing plant and also oil refineries and chemical process industries.
