Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for treating a hydrocarbon feed stream comprising an aromatic compound and a weakly basic nitrogen compound, the method comprising: contacting the hydrocarbon feed stream with a acidic clay at contacting conditions including a temperature of at least about 100° C. and the presence of water in an amount of at least 50 ppm relative to the hydrocarbon feed stream on a weight basis to sequentially convert the weakly basic nitrogen compound to a bas…
