Quick Non Template Production of Molecular Sieve 4a Using Composite Ash: An Ecofriendly Perspective towards Energy and Advanced Materials

Abstract

Recently number of the micro power grid stations in India having capacity of 15 to 20 MW accepted the route of blending rice husk with coal to mitigate the rising cost of coal along with its depletion factor. India being the second largest producer o f rice paddy, rice husk has gained substantial consideration as a potential origin of vitality. The residual ash remains after combu stion refers as composite ash contain silica and alumina which promote the major respiratory diseases. Further, molecular sieve 4A (MS 4A) signify three dimensional network of silicon and aluminum atoms bridged by oxygen linkages. Pore opening of uniform dimensions with high sorption capacity proves the utility of this material in water softening, adsorption, membranes, petrochemical refining process etc.The current paper deals with the experimental attempts for the extraction of sodium silicate using composite ash. Further, it is enriched with sodium aluminate to design MS 4A in a rapid span without inclusion of templates. The investigation studies including XRD, SEM, PSA and IR reveals highly crystalline morphology in the sample. The research work carried out not only suggesting an eco-friendly way to generate energy but also provides a concomitant solution for disposal of waste ash to advanced material.
