MAKING AN OLEFIN PRODUCT FROM AN OXYGENATE
Application IN/PCT/2002/00369/MUM published 2007-03-23, filed 2002-03-26
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.
