摘要/Abstract

摘要： 采用研制的La-Sr-Co-Mn系负载型复合氧化物纳米粒子催化剂对丙烷深度催化氧化进行了小试试验。通过考查催化剂对丙烷气体的氧化程度来考查其对小试装置工艺条件的适应性。试验表明负载型纳米粒子催化剂对装置工艺条件具有很好的适应性。在小型试验装置上催化剂的最佳操作条件为:氧比8~10,空速1 300 h-1,丙烷浓度1.1%。经1 400 h的连续运转,催化剂的活性基本没发生变化,表明了负载型纳米粒子催化剂在考查时间范围内具有良好的稳定性。

关键词: 纳米粒子催化剂, 丙烷, 氧比, 空速

Abstract:

Propane oxidation experiments have been done with La-SrCo-Mn supported nanometer particle catalyst. By investigating he oxidation degrees of propane oxidized by the catalyst, the daptability of the technology condition of experiment equipment has been studied. Results show that the supported
nanometer particle catalyst has good adaptability to the technology condition of equipment, and the best experiment conditions are 8-10(ratio of oxygen), 1300h-1(space velocity) and 1.1% (propane concentration). There is no change in the activity of the catalyst under 1400 hours continuous operation, and it indicates that the catalyst has better stability in the range of investigating time.

Key words: nanometer particle catalyst, propane, ratio of oxygen, space velocity
