Disclosed is a method for removing water, nitrogen compounds, and unsaturated aliphatic compounds from a hydrocarbon feed stream by passing the hydrocarbon feed stream through a water removal zone, a nitrogen removal zone, and an unsaturated aliphatic compound removal zone. By on aspect, the method includes removing water from the hydrocarbon feed stream, contacting the feed stream with a nitrogen selective adsorbent, and contacting the feed stream with an unsaturated aliphatic compound removal material.

Methods and apparatus for treating a hydrocarbon stream

Disclosed is a method for removing weakly basic nitrogen compounds from a hydrocarbon feed stream by contacting the hydrocarbon feed stream with acidic clay to produce a hydrocarbon effluent stream having a lower weakly basic nitrogen compound content relative to the hydrocarbon feed stream. The hydrocarbon feed stream comprises an aromatic compound and a weakly basic nitrogen compound.

Methods for removing weakly basic nitrogen compounds from a hydrocarbon stream using acidic clay

Disclosed is a method for removing weakly basic nitrogen compounds from a hydrocarbon feed stream by contacting the hydrocarbon feed stream with a basic catalyst to convert a portion of the weakly basic nitrogen compounds to basic nitrogen compounds. The method also includes contacting the hydrocarbon feed stream with an acidic adsorbent to adsorb the basic nitrogen compounds from the stream. The hydrocarbon feed stream comprises an aromatic compound and a weakly basic nitrogen compound.
