In this work, the applicability of surgical glove waste pyrolysis oil (SGWPO) combined with pentanol and nano-additives (silicon dioxide (SiO) and nano-graphene) as a substitute fuel for a 5.2 kW-diesel engine is experimentally conducted, aiming to analyze the test engine's performance and emission characteristics. Neat SGWPO could reach 8.6% less BTE, 32.24%, 18.27%, 36.17%, and 9.72% higher NOx, smoke, CO, and HC emissions than diesel at full load. However, blending SGWPO with 25% pentanol by volume and 100 ppm of SiO nanoparticles or 100 ppm of nanographene could improve the engine results. The obtained results of the nanographene-included SGWPO/pentanol blend are lower than SiO-included SGWPO/pentanol blend compared to neat SGWPO. Indeed, the nano-SiO-added SGWPO/pentanol blend demonstrated 9.72% higher BTE and 36.81%, 29.1%, 33.06%, and 25.67% reduced NOx, smoke, CO, and hydrocarbon emissions, respectively, compared to neat SGWPO. Therefore, nano-SiO-included SGWPO/pentanol is recommended as an alternative fuel for diesel engine operation without any modifications. The recommended nanofuel blend usage in engines simultaneously supports much higher engine performance along with reduced emissions, showing the dual benefits of the waste-to-wealth strategy of surgical glove waste.
在本研究中，实验性地探讨了外科手套废热解油（SGWPO）与戊醇及纳米添加剂（二氧化硅（SiO）和纳米石墨烯）混合作为5.2千瓦柴油发动机替代燃料的适用性，旨在分析测试发动机的性能和排放特性。在满负荷工况下，纯SGWPO的制动热效率（BTE）比柴油低8.6%，氮氧化物（NOx）、烟度、一氧化碳（CO）和碳氢化合物（HC）排放分别比柴油高32.24%、18.27%、36.17%和9.72%。然而，将SGWPO与25%（体积）的戊醇以及100 ppm的SiO纳米颗粒或100 ppm的纳米石墨烯混合，可以改善发动机的性能。与纯SGWPO相比，含纳米石墨烯的SGWPO/戊醇混合燃料的实验结果低于含SiO的SGWPO/戊醇混合燃料。实际上，添加纳米SiO的SGWPO/戊醇混合燃料的BTE比纯SGWPO高9.72%，NOx、烟度、CO和碳氢化合物排放分别降低了36.81%、29.1%、33.06%和25.67%。因此，建议使用含纳米SiO的SGWPO/戊醇作为柴油发动机运行的替代燃料，无需任何改装。推荐的纳米燃料混合物在发动机中的使用同时支持更高的发动机性能以及更低的排放，显示了外科手套废料变废为宝策略的双重益处。
