METHODS FOR HIGH YIELD SYNTHESIS OF FURFURAL USING TUNGSTATE/γ-ALUMINA CATALYST |
摘要 |
<p>PURPOSE: A producing method of furfural is provided to improve the yield of the furfural, to reduce the fabrication cost of the furfural, and to reduce the catalyst loss rate. CONSTITUTION: A producing method of furfural using xylose or hemicellulose as a raw material comprises the following steps: converting the raw material into the furfural using a solid acid catalyst body deposited with isopolytungstate to a gamma-alumina supporting body inside a reaction medium including supercritical fluid; and extracting or separating the furfural by spraying the supercritical fluid to the reaction medium. The supercritical fluid is either supercritical carbon dioxide, or supercritical propane.</p> |
