摘要
Many reagents, parameters, and outcomes which are typical in the laboratory are not acceptable at the commercial scale, or are simply not scaleable. Several of these are addressed here. Significant pressure generated via organic template decomposition during BEA zeolite synthesis was addressed with a continuous venting processing scheme. The selection of a less expensive silica raw material source and the development of diafiltration as a product purification method, allowed for significant product cost reduction. Microcalorimetry was shown to be an effective at pinpointing synthesis events in situ. Comparison of nano BEA to a commercial BEA revealed significant differences in external surface area, particle morphology, and activity in a pilot plant catalyst evaluation.
