Biodiesel is a sustainable alternative to petroleum diesel produced by transesterification of vegetable oils in the presence of a catalyst. The present study investigates heterogeneous transesterification of algal oil to biodiesel using novel calcium-doped zinc oxide nanocatalysts synthesized using a UV shaker. The developed catalyst was under different light sources, UV and non-UV; different calcium concentrations (0.01, 0.03, 0.05 M); and different calcination temperatures (600, 700, 800 °C). The catalyst has been characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and energy-dispersive spectroscopy (EDS). The effects of the different parameters used in catalyst preparation were studied for transesterification of algal oil. The catalyst of 0.05 M calcium loading and 700 °C calcination temperature synthesized in UV light is considered as the most suitable nanocatalyst, which achieved 99.18% yield of biodiesel. The catalyst was used three times effectively with 76% yield. The chemical properties of biodiesel have been investigated using gas chromatography (GC).

Ca掺杂的ZnO纳米催化剂从藻类油中高效生产生物柴油

生物柴油是在催化剂存在下通过植物油的酯交换反应生产的石油柴油的可持续替代品。本研究使用新型的掺有钙的氧化锌纳米催化剂(利用紫外线振荡器)研究了藻油向生物柴油的非均相酯交换反应。所开发的催化剂在不同的光源(紫外线和非紫外线)下;不同的钙浓度(0.01、0.03、0.05 M);和不同的煅烧温度(600、700、800°C)。通过扫描电子显微镜(SEM),X射线衍射(XRD),傅里叶变换红外(FT-IR)光谱和能量分散光谱(EDS)对催化剂进行了表征。研究了催化剂制备中使用的不同参数对藻油酯交换反应的影响。催化剂为0。在紫外光下合成的05 M钙和700°C的煅烧温度被认为是最合适的纳米催化剂,其生物柴油的收率为99.18%。有效地使用了催化剂三次,产率为76%。生物柴油的化学性质已使用气相色谱法(GC)进行了研究。
