Abstract
Procedure for sulphuration of natural silicates in order to retain vapours of metals. Procedure for preparation of sulphurated materials from natural silicates and the use thereof for retaining vapours of metals such as mercury. The adsorbent products prepared by the procedure of the invention can be used in the elimination of mercury from gas streams resulting from industrial processes: exhaust gases from thermal power stations, mining, the chloro-alkali industry, urban waste incineration, processing and combustion of fossil fuels, coal, natural gas or petroleum, gasification of coal, and recycling of products (batteries). The present invention relates to the use of natural silicates such as sepiolite, palygorskite or bentonite to the preparation thereof (mechanical, thermal or chemical treatment) to the various procedures for deposition of sulphur in such a way that they can be applied for the retention of vapours of mercury or other heavy metals and to the strategy for the use of solids with reference to sizes, composition, area/volume ratio, depending on the process for purification.
