Upscaling of Zeolite Synthesis

For upscaling of zeolite synthesis, two issues are of key importance [193], viz. the reactor vessel and aU EHS (environmental, health, safety) aspects. Reaction over-run has to be avoided, as illustrated by the phase sequence in MFI synthesis  

From the economic and environmental point of view, the dry-gel synthesis method for large-scale zeolite synthesis seems promising, due to the low template amount needed, the short synthesis time [196], the possibility of direct forming of the dry paste, and elimination of filtration [197]. The use of preformed porous silica spheres has been proposed for impregnation of reactants and in-situ synthesis of zeolites [198].
