| 摘 要：采用松果殼、花生殼、核桃殼及玉米秸稈等自然生物質(zhì)為原料，通過(guò)不完全碳化-濃硫酸磺化兩步制備生物質(zhì)基固體酸催化劑，并將其用于油浴加熱及微波條件下催化單糖轉化為呋喃平臺化合物實(shí)驗中，兩種加熱方式下（150 ℃油浴8 h，160 ℃微波輔助10 min），獲得的糠醛及5-羥甲基糠醛的收率作為其催化性能的評價(jià)指標。果糖轉化實(shí)驗中顯示四種催化劑獲得5-羥甲基糠醛的能力無(wú)明顯差異，5-羥甲基糠醛收率均在70%左右。催化木糖及葡萄糖的活性均表現為核桃殼SC＞松果殼SC＞玉米秸稈SC＞花生殼SC，其中核桃殼SC催化木糖制備糠醛收率可達55.38%，催化葡萄糖制備5-羥甲基糠醛收率可達23.31%。 |

| Abstract：Natural biomass including pine nut shells, peanut shells, walnut shells and corn stalks were used as the raw materials to prepare biomass-based solid acid catalysts through a two-step reactions including incomplete carbonization and concentrated sulfuric acid sulfonation. In the experiment of preparing furan platform compounds by conversion of monosaccharides in oil bath and microwave, the yields of furfural and 5-hydroxymethyl furfural obtained under mild conditions (oil bath: 150 ℃，8 h, microwave: 160 ℃，10 min) which were used as evaluation indicators for the catalytic performance of these four catalysts. The fructose conversion experiment showed that the abilities of the four catalysts to obtain 5-HMF has no significant difference; and the 5-HMF yields were all around 70%; the catalytic activity of carbon from different materials applied in the conversion of both xylose and anhydrous glucose showed that the walnut shell SC> pine Fruit shell SC> corn stalk SC> peanut shell SC; the best catalyst catalyzed xylose to produce furfural with a yield of 55.38%; and catalyzed anhydrous glucose to produce 5-hydroxymethyl furfural with a yield of 23.31%. |
