Process and system for producing ethylene from pyrolysis oil

A process for producing ethylene, the process comprising:

• contacting a feed stream comprising pyrolysis oil with a hydrocracking catalyst disposed within a hydrocracking unit to convert, in the presence of hydrogen, at least a portion of the pyrolysis oil into one or more C2-C4 alkanes to produce a yield in a range of from about 40 wt. % to about 100 wt. % of the one or more C2-C4 alkanes;
• removing a hydrocracking product stream from the hydrocracking unit, the hydrocracking product stream comprising the one or more C2-C4 alkanes;
• diluting the hydrocracking product stream with steam to form a steam cracking feed stream;
• and
• heating the steam cracking feed stream in a steam cracker to convert at least a portion of the one or more C2-C4 alkanes to ethylene.
