摘要
生物燃料是用植物油制成的disel机器的一种替代燃料。叶特法油和玉米油是潜在的生物细胞原料。但jatropha石油原料的生物降解有一个弱点,其中包括较高浓度的粘度和较低的热效率。修理工作之一是将其与玉米油混合。本研究旨在确定混合成分变异对细胞特征的影响。这两种原料都是通过变形反应加工成生物细胞的。接下来是jatropha生物柴油和玉米柴油的混合。这种混合物有9种不同的成分。每一个搅拌混合物成分和在90°C的温度下加热60分钟。研究结果表明,黑素和玉米的生物二醇混合比纯黑素低。生物细胞混合的密度和点也在下降。另一个结果是,混合生物柴油的热电性比纯氯气氯气的热电性高。生物柴油是一种替代柴油燃料,这种燃料通常来自蔬菜油。Jatropha和玉米油是潜在的生物柴油feedstocks。气垫船,jatropha石油公司的生物柴油已经下降,包括高浓度相对论和低热量值。改良其性能的努力是用玉米油混合。这项研究的目的是确定生物柴油性能的影响。两种原料都通过轮化反应进行生物柴油。下一步是混合jatropha和玉米生物柴油。生物柴油搅拌机有九种。每mixture在动,heated at 90°C为60分钟。结果表明,jatropha和玉米生物柴油的混合比jatropha生物柴油还要低。生物柴油搅拌机的密度和闪光点也被除灭。混合生物柴油的热量比纯jatropha生物柴油还要高。
Pengaruh Komposisi Biodisel Jagung Terhadap Sifat-Sifat Campuran Biodisel Jatropha-Jagung
Biodisel merupakan bahan bakar alternatif untuk mesin disel yang biasanya terbuat dari minyak nabati. Minyak jatropha dan minyak jagung merupakan bahan baku biodisel yang potensial. Namun biodisel dari bahan baku minyak jatropha memiliki kelemahan, diantaranya adalah viskositas yang relatif tinggi dan nilai kalor yang relatif rendah. Salah satu upaya perbaikannya adalah pencampuran dengan minyak jagung. Penelitian ini bertujuan untuk mengetahui pengaruh dari variasi komposisi campuran terhadap karakteristik biodisel. Kedua jenis bahan baku diproses menjadi biodisel melalui reaksi transesterifikasi. Selanjutnya dilakukan pencampuran antara biodisel jatropha dan biodiesel jagung. Campuran dibuat dalam sembilan variasi komposisi. Setiap komposisi campuran diaduk dan dipanaskan pada suhu 90 °C selama 60 menit. Hasil penelitian menunjukkan bahwa campuran biodisel jatropha dan jagung memiliki viskositas yang lebih rendah daripada biodisel jatropha murni. Densitas dan titik nyala campuran biodisel tersebut juga mengalami penurunan. Hasil lainnya adalah nilai kalor biodiesel campuran lebih tinggi daripada nilai kalor biodiesel jatropha murni. Biodiesel is an alternative fuel for diesel engines that are usually made from vegetable oil. Jatropha and corn oil are potential biodiesel feedstocks. However, biodiesel from jatropha oil has disadvantages, including high viscosity and relatively low heating value. An effort to improve its properties is mixing it with corn oil. The purpose of this study was to determine the effect of the composition of the mixture on the biodiesel properties. Both raw materials were processed into biodiesel through transesterification reactions. The next step is mixing jatropha and corn biodiesel. There were nine variations of the biodiesel mixture. Each mixture was stirred and heated at 90 °C for 60 minutes. The results showed that the mixture of jatropha and corn biodiesel had lower viscosity than pure jatropha biodiesel. Density and flash point of the biodiesel mixture also decreased. The heating value of mixed biodiesel is higher than its of pure jatropha biodiesel.
