生物柴油是一种被广泛讨论和研究的替代能源。本研究研究了以丙酮和异丙醇（IPA）为燃料的废食用油生物柴油发电机排放的颗粒物（PM）、颗粒物碳和多环芳烃（PAHs）的特征。测试的生物柴油由纯柴油（D100）与1 - 3 vol.%的纯丙酮（记为A）， 1 - 70 vol.%的废食用油生物柴油（记为W）和1 vol.%的纯异丙醇（稳定剂，记为P）组成。结果表明：与W1D99、W3D97、W5D95、W10D90和W20D80相比，生物柴油的使用对PM和颗粒物有机碳（OC）排放有额外的降低作用，且随着纯丙酮添加比例的增加，降低幅度增大；无论添加的食用油-生物柴油、丙酮和异丙醇的百分比如何，使用生物柴油醇代替D100可以减少柴油发动机发电机排放的Total-PAHs（减少6.13-42.5%（平均= 24.1%））和Total-BaPeq（减少16.6-74.8%（平均= 53.2%））。因此，含有丙酮（1 - 3 vol.%）和异丙醇（1 vol.%）的W/D混合燃料（W < 20 vol.%）是柴油发动机发电机的潜在替代燃料，因为它们大大减少了PM、颗粒物OC、Total-PAHs和Total-BaPeq的排放。
Biodiesel is one of alternative energies that have been extensively discussed and studied. This research investigates the characteristics of particulate matter (PM), particulate carbon, and polycyclic aromatic hydrocarbons (PAHs) emitted from a generator fueled by waste-edible-oil-biodiesel with acetone and isopropyl alcohol (IPA) addition. The tested biodieselhols consisted of pure diesel oil (D100) with 1–3 vol.% pure acetone (denoted as A), 1–70 vol.% waste-edible-oil-biodiesel (denoted as W), and 1 vol.% pure isopropyl alcohol (the stabilizer, denoted as P). The results show that in comparison to W1D99, W3D97, W5D95, W10D90, and W20D80, the use of biodieselhols achieved additional reduction of PM and particulate organic carbon (OC) emission, and such reduction increased as the addition percentage of pure acetone increased. Regardless of the percentages of added waste-edible-oil-biodiesel, acetone, and isopropyl alcohol, the use of biodieselhol in place of D100 could reduce the emissions of Total-PAHs (by 6.13–42.5% (average = 24.1%)) and Total-BaPeq(by 16.6–74.8% (average = 53.2%)) from the diesel engine generator. Accordingly, the W/D blended fuels (W < 20 vol.%) containing acetone (1–3 vol.%) and isopropyl alcohol (1 vol.%) are a potential alternative fuel for diesel engine generators because they substantially reduce emissions of PM, particulate OC, Total-PAHs, and Total-BaPeq.
