The present invention provides a non-amorphous, non-ceramic, crystalline, porous, calcined aluminum oxide particles prepared by firing at a particle temperature of 300 to 700 ° C. with contact with dilute acid for a sufficient time to increase the adsorption properties of the aluminum oxide particles. It relates to a method for producing reinforced adsorbent particles. Also described is a process for producing reinforced adsorbent particles in which the non-ceramic, porous, oxidative adsorbent particles consist of contact with an acid for a sufficient time to increase the adsorption properties of the particles. The use of particles, such as the treatment of waste streams and particles produced by the process of the invention, is also provided. The invention also relates to a process for preparing the adsorbent and / or catalyst and binder system. The invention also relates to particles, binders produced by the process and methods for treating contaminants in the stream. The invention also relates to a fixed adsorbent and / or catalyst and binder system. |
