Patent ID: 8652437

Claim:
A method of manufacturing an artificial zeolite which produces an X-ray diffraction pattern of a ZSM-5 type zeolite, the method comprising the steps of: heating a waste insulator used for high voltage or non-industrial voltage and containing silicon at a temperature of between 1300 to 2000 degrees C. to form a molten insulator, wherein the molten insulator comprises silicon and aluminum; quenching and pulverizing the molten insulator; adjusting a ratio of silicon content with respect to aluminum content; and heat treating the quenched and pulverized insulator at a temperature of at least 60 degrees C. in an alkaline aqueous solution, wherein said artificial zeolite has a ratio (Si/AI) of 7.5-5000, and wherein the alkaline aqueous solution comprises sodium hydroxide to which tetra-propyl ammonium and ketone are added.
