EFFICIENT METHOD USING LIQUID WATER TO REGENERATE OXYGENATE TO OLEFIN CATALYSTS WHILE INCREASING CATALYST SPECIFICITY TO LIGHT OLEFINS |
摘要 |
The present invention provides a method for maintaining temperature during regeneration of an oxygenate to olefins catalyst using liquid water as a coolant in an amount sufficient either to reduce duty of a catalyst cooler or to avoid the need to use a catalyst cooler altogether. The method also may be used to hydrotreat fresh, non-hydrothermally treated catalyst which may be added to the regenerator and charged back to the conversion reactor along with the regenerated catalyst.
