Process for the preparation of short-chain olefins from oxygenates |
| abstract |
A process is proposed for the preparation of short-chain olefins by reacting oxygenates in a multistage fixed bed reactor (OTO reactor) with adiabatically operated reaction zones in which the individual stages or reaction zones are packed with beds of a granular, shape-selective zeolite catalyst previously described in US Pat an external, isothermal or quasi-isothermally operated steam pretreatment reactor was subjected to a steam pretreatment. Due to the external steam pretreatment according to the invention, longer service lives of the catalyst used are obtained in comparison with a steam pretreatment in the OTO reactor. The availability of the OTO reactor for olefin production is increased. |
