Abstract
Procedimiento optimizado para la obtención de zeolitas a partir de lejías residuales de la industria de anodización y extrusión, utilizables en la formulación de detergentes. La presente invención contempla la utilización como materia prima de las lejías de decapado previamente filtradas las cuales se mezclan con agua, sosa cáustica y silicato soluble o, preferiblemente, sílice amorfa, para obtener las siguientes proporciones: SiO2/Al2O3: 2.1; Na2O/SiO2: 1.3; H2O/Na2O: 34. A continuación se siguen las etapas convencionales de: Formación del gel (nucleación); envejecimiento (maduración); crecimiento de los cristales y separación del producto sólido. Debido a la presencia en las lejías de decapado de compuestos orgánicos en suspensión procedentes de la descomposición de los gluconatos utilizados para alargar el período operativo del baño así como a la posible precipitación de gibbsita, la primera etapa de formación del gel debe ir precedida de otra etapa de filtración, fundamental para la correcta ejecución del proceso y que, como tal, se reivindica. Las condiciones óptimas operativas son las siguientes: Temperatura de formación del gel: 70°C; temperatura de crecimiento de los cristales: 80°C; tiempo de formación del gel: 3 h; tiempo de crecimiento de los cristales: 3 h.Optimized procedure for obtaining zeolites from residual bleach from the anodizing and extrusion industry, usable in the formulation of detergents. The present invention contemplates the use as a raw material of the previously filtered pickling liquors which are mixed with water, caustic soda and soluble silicate or, preferably, amorphous silica, to obtain the following proportions: SiO2 / Al2O3: 2.1; Na2O / SiO2: 1.3; H2O / Na2O: 34. The following are the conventional steps of: Gel formation (nucleation); aging (maturation); crystal growth and separation of the solid product. Due to the presence in the pickling liquors of suspended organic compounds from the decomposition of the gluconates used to lengthen the operating period of the bath as well as the possible precipitation of gibbsite, the first stage of gel formation must be preceded by another filtration stage, essential for the correct execution of the process and which, as such, is claimed. The optimal operating conditions are as follows: Gel formation temperature: 70 ° C; crystal growth temperature: 80 ° C; gel formation time: 3 h; Crystal growth time: 3 h.
