| 摘 要： | 为了扩大异丁烯的来源,解决甲基叔丁基醚的生产原料问题,文中研究了使用氢气和氢气-水蒸气为稀释剂的情况下,Pt-Sn-K/Al2O3催化剂上异丁烷脱氢生成异丁烯的行为.实验发现:提高反应温度,2种稀释条件下异丁烷的转化率均得到提高,但在氢气-水蒸气稀释条件下异丁烷转化率的增长幅度更大；与单一氢气稀释相比,氢气-水蒸气混合...

| Abstract: | In order to develop more resources of isobutylene as the raw materials of methyl tert-butyl ether(MTBE),the catalytic behavior of Pt-Sn-K/Al2O3 catalyst in the dehydrogenation of isobutane to isobutylene was studied with H2 and H2-steam as diluents.The results show that the conversion of isobutane in H2-steam conditions grows more quickly than that in H2 conditions when heightening the reaction temperature.Compared with using H2 only,using H2-steam as a diluent significantly increases the conversion of isob... |
