| 摘要 |
The invention relates to a method for regenerating catalysts, containing mixed oxides from the group of alkali metals and/or alkaline earth metals, aluminum oxide and silicon oxide, characterized in that the regeneration has the following features: i) treating the catalyst in situ, ii) bringing the catalyst in contact with water, iii) treating the catalyst in a temperature range of 100 to 400°C, iv) treating the catalyst in a pressure range of 0.1 to 2 MPa, v) treating the catalyst over a time period of 0.1 to 24 h, vi) treating the catalyst with a specific catalyst load of 0.1 to 100 h-1.
