Title:

A PRESERVATION METHOD FOR A MICROSPHERE CATALYST USED FOR CONVERTING OXYGEN COMPOUND TO OLEFINE

Document Type and Number:

WIPO Patent Application WO/2008/019578

Kind Code:

A1

Abstract:

A preservation method for a microsphere catalyst used in converting oxygen compound to olefine comprises the following steps: baking the microsphere catalyst in inert atmosphere having no oxygen or a little oxygen under a specific temperature, decomposing the organic substances in the catalyst, leaving compound having a given amount of remnant carbon or lean hydrogen comopound, preserving the carbon containing catalyst under room temperature. The carbon can be removed by baking in air or oxygen containg atmosphere before being used in catalytic reaction. The catalyst obtained by the preservation method has same activity for converting oxygencompound to olefine and selectivity as the fresh baked catalyst.
