    • A method produces a hydrocarbonaceous fluid (a liquid mixture of hydrocarbons, or in other words a mixture of hydrocarbons which is liquid at ambient room temperature and atmospheric pressure), which functionally is a liquid hydrocarbon fuel, from a feed of waste plastic. The method comprises in broad embodiments the steps of: (step 1) melting a feed of substantially solid waste plastic in an aerobic atmosphere (for instance, air) whereby a waste-plastic melt is produced; (step 2) distilling at least a portion of the waste-plastic melt whereby a hydrocarbonaceous distillate is produced; and (step 3) collecting the hydrocarbonaceous distillate. That distillate is generally referred to above as a condensate. In some preferred embodiments, the method includes the step of commutating the feed of substantially solid waste plastic into pieces substantially no greater than about 1.5 cm2 prior to step 1. In preferred embodiments, the method includes the step of adding an effective amount of a cracking catalyst to the waste plastic prior to step 2.
    • 方法从废塑料的进料中产生烃流体(烃的液体混合物,或换句话说是在室温和大气压下为液体的烃的混合物),功能上是液体烃燃料。 该方法在广泛的实施方案中包括以下步骤:(步骤1)在有氧气氛(例如空气)中熔化基本上固体废塑料的进料,由此产生废塑料熔体; (步骤2)蒸馏至少一部分废塑料熔体,由此产生含烃馏出物; 和(步骤3)收集含烃馏出物。 该馏出物通常称为冷凝物。 在一些优选的实施方案中,该方法包括在步骤1之前将基本上固体的废塑料的进料换成基本不大于约1.5cm 2的片的步骤。在优选的实施方案中,该方法包括以下步骤:加入有效量的裂化 在步骤2之前对废塑料的催化剂。
