The study investigated a method of synthesizing a pitch suitable for making activated carbon using fluid catalytic cracking-decant oil (FCC-DO), a high-purity carbon precursor from oil refining. We kept the reaction time and catalyst amount constant while varying the temperature to investigate its impact on pitch synthesis and the resulting physical and activation properties. Previous research established that materials added during pitch synthesis can affect the properties of both the pitch and resulting activated carbon. This study examined the addition of polyethylene terephthalate (PET) to FCC-DO-based pitch. The results indicated significant changes in properties with PET addition and temperature variation that ensured stable activated carbon quality. At temperatures of 390 °C or higher, the specific surface area of the activated carbon stabilized between 2680 and 2740 m²/g. Waste PET, a recyclable plastic, was chosen due to its compatibility and thermodynamic suitability for pitch synthesis. Importantly, adding PET didn't generate additional waste or degrade the physical properties of the activated carbon.

该研究研究了一种使用流化催化裂化倾析油（FCC-DO）（一种来自炼油的高纯度碳前体）合成适合制造活性炭的沥青的方法。我们保持反应时间和催化剂用量恒定，同时改变温度，以研究其对沥青合成以及由此产生的物理和活化性能的影响。先前的研究表明，在沥青合成过程中添加的材料会影响沥青和所得活性炭的性能。本研究考察了在 FCC-DO 沥青中添加聚对苯二甲酸乙二醇酯 (PET) 的情况。结果表明，随着 PET 添加和温度变化，性能发生显着变化，从而确保活性炭质量稳定。在390℃或更高的温度下，活性炭的比表面积稳定在2680至2740m ² /g之间。废PET是一种可回收塑料，因其与沥青合成的相容性和热力学适用性而被选中。重要的是，添加 PET 不会产生额外的废物或降低活性炭的物理性能。
