A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. More particularly cracker feedstock comprises a recycle content pyrolysis oil composition (r-pyoil), wherein the cracker feedstock has a boiling point curve defined the following characteristics (i) through (iii): (i) a 90% boiling point at least 350 DEG C; (ii) a 10% boiling point of at least 60 DEG C; and (iii) a 50% boiling point in the range of from 95 to 200 DEG C. 烃裂化器流与回收成分热解油组合以形成组合裂化器流，且组合裂化器流在裂化器炉中裂化以提供含烯烃流出物。r-热解油可进料至裂化器进料。更特别地，裂化器原料包含回收成分热解油组合物(r-热解油)，其中裂化器原料具有由以下特征(i)至(iii)限定的沸点曲线：(i)90％沸点为至少350℃；(ii)10％沸点为至少60℃；以及(iii)50％沸点在95℃至200℃的范围内。
