METHOD FOR PRODUCING OLEFIN OLIGOMERS,USING A MODIFIED MORDENITE BASED CATALYST

摘要

A process for the production of oligomers in which at least one monoolefin containing from 2 to 8 carbon atoms is placed in contact with a catalyst based on modified mordenite. …This mordenite has been obtained by the following successive stages:… a) a non-dealuminised (H or NH4<+>) mordenite is subjected to a treatment with steam at a temperature of at least 450 DEG C at a steam partial pressure greater than 60%, and… b) the resulting product is treated at least once with an acid at a concentration of between 0.5 and 20N. …Application to the production of motor vehicle premium grade fuel, jet propulsion fuel and diesel fuel.
