Abstract Liquid hydrocarbons obtained from the pyrolysis of polypropylene and polystyrene were used as diluents to reduce the viscosity of a Mexican heavy crude oil of 10.6°API. Blends of oil and diluents were formulated with fractions of 5, 10 and 15 vol% of diluent. Viscosity results were plotted as a function of temperature and diluent volume fractions. The degree of viscosity reduction at room temperature was of 96 – 97% using 15 vol% of the proposed materials. Results show that viscosities lower than 400 cP, the classical maximum for pipeline transportation, are achieved at relatively low temperatures (45 – 65 °C).

通过用聚丙烯和聚苯乙烯热解获得的烃稀释来降低重质原油粘度

摘要 以聚丙烯和聚苯乙烯热解得到的液态烃为稀释剂，降低了墨西哥10.6°API重质原油的粘度。油和稀释剂的混合物用稀释剂的 5、10 和 15% 体积分数配制。粘度结果绘制为温度和稀释剂体积分数的函数。使用 15 vol% 的建议材料，室温下的粘度降低程度为 96 – 97%。结果表明，粘度低于 400 cP（管道运输的经典最大值）是在相对较低的温度 (45 – 65 °C) 下实现的。
