Abstract:
The present disclosure relates to a method including subjecting an organic stream comprising at least one oxygenate to hydrotreatment, whereby a hydrotreatment product comprising ethylbenzene is produced, wherein the organic stream is a product of a process for the production of propylene oxide; and separating an ethylbenzene product stream from the hydrotreatment product, to yield a residual stream.

Claim (Index 9):
The method of  claim 8 , wherein the organic stream is a product of a process for the co-production of propylene oxide and styrene (POSM), and wherein removing at least a portion of the contaminant prior to hydrotreatment comprises:\n (c) contacting the organic stream with water and carbon dioxide, whereby sodium is extracted from the organic stream, and separating an aqueous sodium-containing slurry phase from an organic phase comprising a reduced sodium content relative to the organic stream; passing the organic stream over a catalyst guard bed prior to hydrotreatment; or both contacting the organic stream with water and carbon dioxide, whereby sodium is extracted from the organic stream, and separating an aqueous sodium-containing slurry phase from an organic phase comprising a reduced sodium content relative to the organic stream; and passing the organic stream over a catalyst guard bed prior to hydrotreatment; or (d) subjecting the organic stream to an acid wash and subsequent neutralization to provide the pretreated organic stream; passing the organic stream over a catalyst guard bed prior to hydrotreatment; or both subjecting the organic stream to an acid wash and subsequent neutralization to provide the pretreated organic stream and passing the organic stream over a catalyst guard bed prior to hydrotreatment.
