| 1 | 间苯二甲腈加氢制间苯二甲胺催化剂研究显示文摘采用浸渍法制备了间苯二甲腈加氢合成间苯二甲胺所用的催化剂。详细考察了负载金属类型、金属负载量(质量分数)、载体类型、焙烧温度、还原温度等条件对催化剂性能的影响。结果表明,采用Ni/Al_2O_3催化剂,当镍负载量为10%,焙烧温度为723 K,还原温度为773 K时,催化剂的反应性能最好,间苯二甲腈转化率为99%,间苯二甲胺选择性为98%。 | 张怡 宁春利 | 2016 | 上海化工2016，41，7： | 2 |
| 2 | Synergetic effects of NaAlH_4-TiF_3 co-additive on dehydriding reaction of Mg(AlH_4)_2显示文摘The effects of Na Al H4, Ti F3 and Na Al H4-Ti F3co-additive on dehydriding reaction of Mg(Al H4)2are systematically investigated. The onset dehydrogenation temperature of the co-doped Mg(Al H4)2composites decreased to 74°C, which is about 59°C lower than that of pure Mg(Al H4)2. The dehydrogenation kinetics of Na Al H4-Ti F3co-doped Mg(Al H4)2sample was also improved, which released about 94%hydrogen within 48 min, but no visible hydrogen was released from pure Mg(Al H4)2under the same conditions. The activation energy of co-doped Mg(Al H4)2was 85.6 k J mol-1, which was significantly lower than that of additive-free Mg(Al H4)2sample. The synergetic effects of Na Al H4 and Ti F3 on the dehydrogenation performance of Mg(Al H4)2were confirmed. In addition, a possible catalytic mechanism is discussed, regarding the different roles of Na Al H4 and Ti F3 on Mg(Al H4)2. | Ying Wang Li Li Fangyuan Qiu Cuihua An Yijing Wang Lifang Jiao Huatang Yuan | 2014 | Journal of Energy Chemistry2014，23，6： | 0 |
