| abstract |
The invention relates to a catalyst composition, a method of making the same and its use in the conversion of a feedstock, preferably an oxygenated feedstock, into one or more olefin(s), preferably ethylene and/or propylene. The catalyst composition comprises a molecular sieve and at least one metal oxide, such as magnesium oxide that, when saturated with acetone and contacted with said acetone for 1 hour at 25 °C, converts more than 80 % of the acetone. |
