Abstract
A process for the production of olefins which comprises passing an oxygenate-containing feedstock over a zeo type catalyst at a temperature greater than 200.degree. C. characterized in that the oxygenate-containing feedstock comprises C.sub.3 and/or C.sub.4 olefins and as oxygenate methanol formaldehyde and/or dimethylether, the molar ratio of olefin to oxygenate being greater than 1:20 and the zeo type catalyst being of TON-type structure.
Claims8
A process for the production of olefins which comprises passing an oxygenate-containing feedstock over a zeo-type catalyst at a temperature greater than 200.degree. C. wherein the oxygenate-containing feedstock comprises C.sub.3 and/or C.sub.4 olefins, the oxygenate is at least one of methanol, formaldehyde or dimethylether, the molar ratio of olefin to oxygenate being greater than 1:20, and the zeo-type catalyst is of a TON-type structure and is selected from the group consisting of aluminosilicates, gallosilicates, zincosilicates, borosilicates, titanosilicates, aluminogermanates, gallogermanates, zincogermanates, borogermanates and titanogermanates.
