Abstract
The topic of the present invention is the development of a method of producing inexpensive artificial zeolite of the desired quality employing unused resources, such as descended pyroclastic materials, incineration ash, glass waste, diatomaceous earth waste, aluminum dross, etc., as the starting materials. The present invention is a method whereby artificial zeolite is produced by heat treatment in the presence of water and alkali of an inorganic component comprising silicic acid or aluminum, or a mixture that has been obtained by adding glass, diatomaceous earth and aluminum dross, etc., to an inorganic component comprising silicic acid or aluminum. It is preferred that the alkali is sodium hydroxide or potassium hydroxide, the water and alkali are an aqueous alkali solution, the concentration of this aqueous alkali solution is 2 to 4 N, and heat treatment exceeds 100° C.
