Abstract: A process is provided for treating a stream comprising light olefins and carbon monoxide by passing the stream through a bed containing a copper containing material. The carbon monoxide needs to be removed in order to prevent poisoning of catalysts in downstream oligomerization reactors. This carbon containing material converts the carbon monoxide and hydrogen to carbon dioxide and water. The olefin stream is then dried and sent to an oligomerization step. There may be three beds so that the beds may alternate regeneration, reaction with CO and H2 and scavenging O2 steps.

Abstract: The process produces a diesel from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The biorenewable feedstock is contacted in a guard bed reactor in the presence of hydrogen to saturate olefins and remove metals to produce a contacted feed stream. The contacted feed stream is then heated in a charge heater to a higher temperature than in the guard bed reactor and hydrotreated in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to deoxygenate the contacted feed stream to provide a hydrotreated stream.

Abstract: Process and apparatus for recovering a product stream from a waste plastic feedstock and reducing the endpoint of the product stream is provided. A polymer oil is produced as a product stream by pyrolyzing the waste plastic feedstock in a pyrolysis reactor to produce a pyrolysis vapor and passing the pyrolysis vapor to a condenser. A drag stream from the pyrolysis reactor is further pyrolyzed to convert the polymer oil to pyrolysis oil which is vaporized under pyrolysis conditions to vaporous pyrolysis oil and dry char. Vaporous pyrolysis oil is recovered to enhance conversion and fed to a condenser using a liquid jet ejector.
