| 摘 要： | 合成了活性炭(AC)担载的硅钨酸(H4[SiW12O40].nH2O,HSiW)催化剂,并研究了其对甘油脱水制丙烯醛的催化性能.结果表明,10%HSiW/AC催化剂具有较高的活性和选择性,反应生成丙烯醛的时空收率可达68.5 mmol/(g.h),为文献报道的最好结果之一.催化剂的性能与催化剂表面杂多酸的分散度以及强酸中心的相对数量密切相关. |

| Abstract: | Activated carbon (AC)-supported silicotungstic acid (H4[SiW12O40]·nH2O, HSiW) catalysts were employed to produce acrolein from glycerol dehydration. The results indicated that catalysts with 10% HSiW loading exhibited the highest activity and selectivity. The space time yield of acrolein reached 68.5 mmol/(g·h), which is the best result ever reported in the literature. The properties of the catalysts were closely related to the HSiW dispersion and the relative quantities of strong acid sites. |
| Keywords: | silicotungstic acid activated carbon supported catalyst glycerol dehydration acrolein |
