[B]ABSTRACT:[/B]

Proper utilization of fly ash has become a pressing issue today. Large quantity of fly ash is produced by the coal fired thermal power plants throughout the world, In India, more than 90 million tons of fly ash is being generated annually with 65 000 acres of land being occupied by ash ponds. The World Bank has cautioned India that by 2015, disposal of coal ash would require 1000 square kilometers or one square meter of land per person. Currently coal based thermal power plants contribute 70% of power production in the country generating a massive amount of fly ash. This is causing tremendous impact on environment in India
In view of high cost of disposal and environmental pollution, the gainful utilization of fly ash to maximum extent is of vital importance. Therefore, development of a technique for the treatment of coal fly ash is indispensable to the recycling and utilization of waste matters.
In the present project an attempt has been made to synthesize zeolite from waste coal fly ash, and utilize this treated fly ash as catalyst for industrially important processes like catalytic cracking of n-heptanes.
