Patent

CA 2257509

This invention relates to a process for producing an enhanced adsorbent particle comprising contacting a non-amorphous, non-ceramic, crystalline, porous, calcined, aluminum oxide particle that was produced by calcining at a particle temperature of from 300 ~C to 700 ~C, with an acid for a sufficient time to increase the adsorbent properties of the particle. A process for producing an enhanced adsorbent particle comprising contacting a non-ceramic, porous, oxide adsorbent particle with an acid for a sufficient time to increase the adsorbent properties of the particle is also disclosed. Particles made by the process of the instant invention and particle uses, such as remediation of waste streams, are also provided. The invention also relates to a method for producing an adsorbent and/or catalyst and binder system. The invention also relates to particles made by the process, binders, and methods for remediating contaminants in a stream. The invention also relates to an anchored adsorbent and/or catalyst and binder system.

Procédé de production d'une particule adsorbante améliorée qui consiste à mettre en contact une particule d'oxyde d'aluminium non amorphe, non céramique, cristalline, poreuse, calcinée qui a été produite par calcination à une température de particule de 300· C à 700· C, avec un acide pendant un laps de temps suffisant pour augmenter les propriétés adsorbantes de ladite particule. Un procédé de production d'une particule adsorbante améliorée qui consiste à mettre en contact une particule d'oxyde adsorbante non céramique, poreuse avec un acide pendant un laps de temps suffisant pour augmenter les propriétés adsorbantes de ladite particule est également décrit. Les particules préparées selon le procédé de la présente invention et les utilisations desdites particules, telles que le traitement d'eaux usées, sont également décrites. La présente invention concerne encore un procédé de production d'un système adsorbant et/ou catalyseur et liant, des particules produites selon ledit procédé, des liants et des procédés d'élimination de contaminants dans un flux. Elle concerne enfin un système d'adsorbant et/ou de catalyseur et de liant ancré.
