Sulfiding procedure natural silicates to retain metal vapors.

Sulfiding procedure natural silicates to retain metal vapors. Process for preparing sulfurized materials from natural silicates and their use to retain metal vapors such as mercury. Adsorbents products prepared by the process of the invention can be employed in the removal of mercury from gas streams from industrial processes: flue gases from thermal, mining, chlor-alkali, incineration of municipal products, processing and combustion of fossil fuels, coal, oil or natural gas, coal gasification product recycling (batteries, batteries). The present invention relates to the use of natural silicates such as sepiolite, palygorskite or bentonite; to the preparation thereof (mechanical treatment, thermal, chemical); the various deposition processes sulfur so that they can be applied to the retention of mercury vapor, or other heavy metals and the strategy of use of solid as regards sizes, shaped, area / volume ratio, in function object debugging process.
