Gas-phase dehydration reaction process |
摘要 |
Here is provided a process capable of efficiently carrying out a gas-phase dehydration reaction comprising contacting a raw material gas with a solid oxide catalyst containing an alkali metal element to allow reaction to progress by inhibiting decomposition of the raw material and the objective product. This process comprises using a sintered oxide comprising an alkali metal element and silica and/or alumina as a loading material for preheating of the raw material gas and/or as a supporting material for fixation of the position of the catalyst. |
