Abstract:
1. A process for oligomerizing ethylene comprising: providing a feed stream comprising between about 5 and about 50 wt-% ethylene, between about 25 and about 55 wt-% methane and at least one impurity selected from the group consisting of at least about 0.1 wt-% carbon monoxide, at least about 1 wppm hydrogen sulfide, at least about 1 wppm ammonia, at least about 5 wt-% hydrogen and at least about 0.1 wt-% carbon dioxide; contacting the feed stream with a catalyst comprising an amorphous silica-alumina base with a silica-to-alumina ratio of no more than 20 and a metal selected from the group consisting of Group VIII and Group VIB in the periodic table; and converting at least 40 wt-% of the ethylene in the feed stream to heavier hydrocarbons.
