PROCESS FOR PREPARING NORMALLY LIQUID HYDROCARBONACEOUS PRODUCTS FROM A HYDROCARBON FEED CONTAINING LINEAR-AND BRANCHED OLEFINS

摘要

The invention relates to a process for preparing normally liquid hydrocarbon products, such as middle distillates and methyl-t-butylether, from a hydrocarbon feed containing linear and branched olefins (e.g. propane and butenes in light ends) comprising at least the following steps: i) selectively converting branched olefins in the feed in the presence of a catalyst into a normally liquid hydrocarbonaceous product (e.g. MTBE); ii) separating linear olefins from product obtained in step (i), and iii) catalytically oligomerizing linear olefins obtained from step (ii) into liquid hydrocarbons such as middle distillates. y
