Abstract

The present invention relates to microwave assisted process for the synthesis of molecular sieves from pseudo and/or dry carbon loaded gels comprising the steps of preparing pseudo and/or dry gel; carbon loading of the pseudo and/or dry gel to obtain carbon loaded pseudo and/or dry gel; treating the carbon loaded pseudo and/or dry gel at optimum microwave conditions of optimum temperature, optimum microwave power and optimum ramping time; crystallizing the product to obtain crystallized molecular sieves; and optionally calcination of crystallized molecular sieves to obtain calcined molecular seives.
