Methods of producing a polyolefin wax product are provided herein. In an embodiments, a method of producing a polyolefin wax product includes providing a cracked polyolefin vapor phase and a polyolefin liquid phase that are derived from a recycled polyolefin feedstock having a higher number average molecular weight than the polyolefin wax product. A portion of the cracked polyolefin vapor phase iscondensed at a temperature and pressure above a boiling point of olefins having less than or equal to 12 carbon atoms to produce the polyolefin wax product. 本文提供生产聚烯烃蜡产物的方法。在个实施方案中，生产聚烯烃蜡产物的方法包括提供衍生自比聚烯烃蜡产物具有更高数均分子量的再循环聚烯烃原料的裂化聚烯烃蒸气相和聚烯烃液相。将部分裂化聚烯烃蒸气相在高于具有小于或等于12个碳原子的烯烃的沸点的温度和压力下冷凝以产生聚烯烃蜡产物。
