Zeolite flow chart

To help carry out such an evaluation we have prepared a flow chart, shown in Table V, which presents the important considerations in a systematic manner. These are two main branches, zeolite selection and process feasibility. The process feasibility initially assumes the worst case for the design parameter estimates, but these can be revised if the zeolite selection process indicates that higher capacity or shorter MTZ might be encountered.

In context to the characterization of the S3uithesized zeolites, it has been reported that the quantity of zeoUtic minerals present in the end product has been found to vary widely ( 20-65 % by weight of fly ash), mainly depending on the various parameters (viz., type of fly ash, alkali concentration, temperature, time and liquid to solid ratio) involved in the synthesis process. A t3q>ical flow chart is depicted in Fig. 3.1 to highlight the different procedural steps required for this method. 

In view of the production of alkaline supernatant/waste solution after hydrothermal and fusion methods, a molten salt method has been demonstrated by previous researchers for synthesis of zeolites by employing a dry conversion technique without use of water. In tune with this, mixture of chemicals/salts and fly ash has been reported to yield zeolites by reaction of salts in molten condition for a period up to 3 days. A flow chart of the synthesis process is depicted in Fig. 3.4 [15, 16].
