Abstract
The present invention provides a process for preparing ethylene and/or propylene, comprising the steps of providing a hydrocarbon stream, comprising C4+ normal olefins and C4+ iso-olefins; converting C4+ isoolefins to tert-alkyl ether and separating the ethers from the hydrocarbon stream; isomersing the C4+ normal olefins to iso-olefins and converting C4+ isoolefins to tert-alkyl ether and separating the ethers from the hydrocarbon stream; converting the obtained tert-alkyl ether to ethylene and propylene by contacting the tert-alkyl ether with a molecular sieve-comprising catalyst and retrieving an olefinic product.
