The products yield change in pyrolysis of natural 伊Iiquid (NGL) , 恤P严d oil and co-pyrolysis 切由 naphtha in a bench-scale pyrolysis apparat血， are studied. 币le results show 也础，由e pyrolysis of NGL and lopped oil pyrolysis alone are superior to that co啊rolyzed wi由皿phtha.ηle feasibility of the 00- pyrolysis of topped oil and NGL is investigated.
