1. Loaded activated carbon is afterwards treated with steam to desorb the adsorbed contaminants.

2. In order to absorb, adsorb or desorb ammonia, ammonia or a carrier gas supplied with ammonia is passed through or along a material containing a 3d transition metal complex salt.

3. Also, it relates to an absorbent that can be used in humidifiers, dehumidifiers and coolers/heaters, which can easily absorb or desorb at 100°C and below, and has a great absorption amount per weight of the absorbent.

4. Reusable petroleum absorbent namely, polymer-based media used for environmental clean-up and water treatment that will absorb and adsorb, coalesce and desorb the oil, gas and other hydrocarbons and non-aqueous phase elements, from water and other aqueous liquids

5. The desiccant assisted air conditioning system comprises a process air path (A) for flowing process air to adsorb moisture from the process air by a desiccant member, and a regeneration air path (B) for flowing regeneration air heated by a heat source to desorb moisture from the desiccant member (103).

6. The method further includes permitting the desiccant - bearing porous insulating material to adsorb water moisture from the attic space and then permitting the adsorbed water moisture to desorb from the desiccant - bearing porous insulating material into the enclosed room of the building, resulting in a reduction in the amount of energy required to heat and cool the building.
