摘要/Abstract

摘要：

A new route to synthesize TS-1 has been developed using the supercritical carbon dioxide(SCCO₂) as a crystallization-assistant agent. SCCO₂ plays a dual role: as a reagent changing the alkalinity during the crystallization process and as a medium eliminating mass-transfer limitations(both within the bulk fluid and through liquid/gas, solid/gas or solid/liquid phase boundaries). In this route, it was shown that the Ti content in TS-1 increase compared with that in the TS-1 prepared without SCCO₂, but decrease while the SCCO₂ pressure increase. The prepared crystal morphology also underwent significant change. The crystallization time of TS-1 can be shorten a lot.
