摘要

生物燃料是一种可替代的环境友好型能源,起源于化石燃料的使用,并在过去几十年中导致了显著增长的需求。由于生物柴油通常是从可再生资源如植物油和动物油中获得的,例如椰子油是从椰子中提取的,然后进行表征以供进一步使用。本研究的目的是研究从楝树油生产生物柴油,并表征影响生物柴油性能的参数。采用反式酯化工艺制备生物柴油,皂化值为191 mg KOH/g,碘10 mgl2/g,酸14.0 mg KOH/g,密度0.91 g,粘度23 mm2/s,闪点266℃。该生物柴油的密度为820 kg/m3,粘度为3.5 mm2/s,皂化值为91 mg KOH/g,碘值为8.9 mgl2/g,酸含量为30.8 mg KOH/g,闪点为110℃。获得的物理化学性质也与ASTM规格范围内的标准生物柴油进行了比较。

Biodiesel Production from Neem Seed ( Azadirachta indica ) Oil Using Calcium Oxide as Heterogeneous Catalyst
Biofuel is an alternative and environment friendly source of energy, originated by the use of fossil fuels and have led to a notable growing demand from the last few decades. As biodiesel are usually acquired from renewable sources like vegetable and animal oils, for example coconut oil is extracted from the coconut and then characterized for further usage. The aim of this study is to investigate the production of biodiesel from neem oil and to characterize the parameters that affect biodiesel performance. The Biodiesel was produced using trans-esterification process resulting in the values of saponification 191 mg KOH/g, iodine 10 mgl2/g, acid 14.0 mg KOH/g, density 0.91 g, viscosity 23 mm2/s and flash point 266°C. The biodiesel was also characterized and showed that the it has density of 820 kg/m3, viscosity 3.5 mm2/s, saponification value 91 mg KOH/g, iodine value 8.9 mgl2/g, acid content 30.8 mg KOH/g and flash point 110°C. The physicochemical properties obtained were also compared to standard biodiesel in the range of ASTM specifications.
