摘要： Disclosed is a method for making olefin product from an oxygenate-containing feedstock. In the method, a silicoaluminophosphate molecular sieve catalyst is contacted with the oxygenate-containing feedstock in a reactor at an average catalyst feedstock exposure index of at least 1.0. The method produces lower coke yield and provides an olefin product which is low in C1-C4 paraffin content. The invention is particularly effective in producing an olefin product having a very low propane content.

摘要： Disclosed is a method of making an olefin product from an oxygenate feedstock comprising, contacting the feedstock in a reaction zone containing 15 volume percent or less of a catalyst, preferably a catalyst comprising a silicoaluminophosphate molecular sieve. In order to obtain the desired product content, i.e., an olefin product having a low level of by-products, conversion of the feedstock in the 15 volume percent or less reaction zone should be maintained between 80 wt% and 99 wt% at the conditions effective to convert 100 wt% of the feedstock when the reaction zone contains at least 33 volume percent of the catalyst material.
