A method for preparing a sorbent precursor, which may be sulphided and used to remove heavy metals such as mercury from fluid streams, includes the steps of: (i) mixing together an inert particulate support material and one or more binders to form a support mixture, (ii) shaping the support mixture by granulation in a granulator to form agglomerates, (iii) coating the agglomerates with a coating mixture powder including a particulate copper compound and one or more binders to form a coated agglomerate, and (iv) drying the coated agglomerate to form a dried sorbent precursor.

A water filtration media which prevents or resists the accumulation of microbes while simultaneously addressing the added problem of leaching caused by the treatment of activated carbon. In one preferred embodiment, the combination of Cu and Ag on activated carbon is prepared. Steps are taken to bind the silver and copper using anionic surfactant so that there is less leaching of silver and copper from the media. In a separate embodiment, the combination of Cu and Zn is prepared, which is subjected to high temperature for better binding of the metal oxides with the carbon.

The present disclosure described compositions which may be effective in removing contaminants from a gas stream such as nitrous oxides. The composition may include a sorbent which contains triethylenediamine and a metal including copper, zinc, or a combination thereof. Methods of making such a composition are also described, along with devices which use the composition to remove contaminants from fluid streams, particularly in vehicle tunnels and parking garages.

The invention relates to a process for the manufacture of a porous composite material for use in a gas/solid reaction system. The process includes combining at least one active ingredient, organic binder and an inorganic binder to form a mixture, adding water to form green pellets, partially drying and curing the pellets to form a composite material formed from cured pellets having a crushing strength of 4000 g/pellet-20000 g/pellet, suitable for use in a gas/solid reaction system.
