Abstract
The invention provides a process for the preparation of an olefinic product, the process comprising reacting an oxygenate feedstock in the presence of formulated oxygenate conversion catalyst particles to produce the olefinic product, the formulated catalyst particles comprising a combination of at least a molecular sieve having one-dimensional 10-membered ring channels and a matrix wherein a Group II metal species has been added to the catalyst particles after the combination of said molecular sieve and the matrix. Further a process for the manufacture of formulated oxygenate conversion catalyst particles, comprising combining of at least a molecular sieve having one-dimensional 10-membered ring channels and a matrix to form catalyst particles, and adding a Group II metal species to the catalyst particles after the combination of said molecular sieve and the matrix; and also oxygenate conversion catalyst particles comprising a combination of at least a molecular sieve having one-dimensional 10-membered ring channels, a further molecular sieve having more-dimensional channels, a matrix, and a Group II metal species.
