调控分子筛B酸和L酸比例用于催化糠醛高值转化
Regulating the Ratio of B Acid and L Acid in Zeolites for High-Value Conversion of Furfural
摘要
Abstract
As important biomass platform molecules,isopropyl levulinate and γ-valerolactone have promising applications in the production of chemicals,liquid fuels and polymerization.The acidity-tunable P-Zr/H-Beta bifunctional catalyst for the selective conversion of furfural to γ-valerolactone and isopropyl levulinate were prepared.The catalyst could effectively catalytic production of γ-valerolactone and isopropyl levulinate from furfural via transfer hydrogenation,ring opening and cyclization reactions with isopropanol as the hydrogen donor.The yields of γ-valerolactone and isopropyl levulinate were 41.6%and 23.7%,respectively,with a total yield of 65.3%at 150℃.The reaction activity of transfer hydrogenation mainly depended on the acid-base sites of catalyst,which was determined by the molar ratio of P to Zr in P-Zr/H-Beta.In addition,the effects of reaction parameters such as time and temperature on the yield of γ-valerolactone were explored;and the structure of P-Zr/H-Beta was further characterized in detail.关键词
