Abstract
Procedimiento de sulfuración de silicatos naturales para retener vapores de metales. Procedimiento de preparación de materiales sulfurados a partir de silicatos naturales y su utilización para retener vapores de metales, como mercurio. Los productos adsorbentes preparados por el procedimiento de la invención pueden emplearse en la eliminación de mercurio de corrientes gaseosas resultantes de procesos industriales: gases de salida de térmicas, minería, industria cloro-álcali, incineración de productos urbanos, tratamiento y combustión de combustibles fósiles, carbón, gas natural o petróleo, gasificación de carbón, reciclado de productos (pilas, baterías). La presente invención se refiere a la utilización de silicatos naturales como sepiolita, palygorskita o bentonita; a la preparación de los mismos (tratamiento mecánico, térmico, químico); a los diversos procedimientos de deposición de azufre de manera que puedan ser aplicados a la retención de vapores de mercurio, u otros metales pesados ya la estrategia de utilización de los sólidos en lo que se refiere a tamaños, conformado, relación área/volumen, en función del proceso objeto de depuración.Sulfidation procedure of natural silicates to retain metal vapors. Procedure for preparing sulfur materials from natural silicates and their use to retain metal vapors, such as mercury. The adsorbent products prepared by the process of the invention can be used in the removal of mercury from gas streams resulting from industrial processes: exhaust gases from thermal power plants, mining, the chlor-alkali industry, incineration of urban products, treatment and combustion of fossil fuels, coal, natural gas or oil, gasification of coal, recycling of products (batteries, batteries). The present invention relates to the use of natural silicates such as sepiolite, palygorskite or bentonite; to their preparation (mechanical, thermal, chemical treatment); to the various sulfur deposition procedures so that they can be applied to the retention of vapors of mercury, or other heavy metals, and to the strategy of using solids in terms of sizes, shape, area / volume ratio, in function of the process being debugged.
