Title:
SIMPLE PROCESS FOR PRODUCTION OF ZEOLITE ANALOGUES FUNCTIONING AS ACID CATALYSTS
Document Type and Number:
WIPO Patent Application WO/2004/007370
Kind Code:
A1
Abstract:
A process for producing a raw material for the formation of proton-exchanged zeolite analogues whose cations are wholly or partially exchanged by H+ and which contain zeolite having tektosilicate structure, characterized by the step of treating a mineral with an acid solution; and a process of reacting a sugar donor with a sugar acceptor in the presence of a supercritical fluid as the solvent by using the proton-exchanged zeolite analogue itself as the catalyst to form a sugar -containing substance.
