Amorphous alumino-silicate beads prodn. by sol-gel process - by dropping thin stream of freshly mixed aluminate and silicate soln. into forming oil

Prodn. is carried out by combining an aluminate and a silicate soln., opt. contg. other components, and immediately introducing the mixt. in a thin stream into a forming oil by the sol-gel process. The gel beads formed are subjected to other well-known stages of the sol-gel process. The beads are specified for use as catalyst, catalyst support, adsorbent or desiccant. A droppable mixt. is obtd., whereas previously a gel has formed immediately. It allows the use of cheap aluminate solns., e.g. waste liquors from synthetic zeolite mfr., instead of costly Al salt solns., and of fines from other processes, e.g. silica gel bead or zeolite mfr., and can be carried out in the usual plant for the sol-gel process.

Treatment of clay minerals

Acid-activated clay mineral which has been washed so that the acidity is less than 2% is purified by intimately contacting an aqueous slurry or suspension thereof with a cation exchange resin in the hydrogen, alkali metal or ammonium form and subsequently isolating the resin. If the hydrogen form of the resin is used the acidity so-imparted may be reduced by means of an anion exchange resin in the hydroxyl form or by treatment with a suitable alkali metal compound such as sodium hydroxide which may be in aqueous solution. The slurry and resin may be stirred and fed to a screen to separate the resin. The resin may be regenerated by passing countercurrently downwards through a column fed with hydrochloric acid (e.g. 10% by weight). After washing the resin may be reused. The slurry may contain 20 to 35% by weight of clay. The treatment may be effected at below 100 DEG C., e.g. 50 DEG to 70 DEG C., and may be carried out by passing the slurry through a continuously pulsed column of resin (jigged ...

Activated bleaching clay

Finely-divided clay, e.g. bentonite, is mixed with concentrated sulphuric acid, which is substantially free of water, usually of a quantity enough to activate the clay and to produce a free-flowing mixture, e.g. 5-40 per cent by weight of acid, and subsequently contacting this mixture with steam. Preferably the clay/acid mixture is heated to 100 DEG C. before the steam treatment, e.g. by fluidizing with heated air.

Treatment of clay

Attrition resistant hardened zeolite materials for air filtration media

Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.
