The present study aimed to enhancement production of the biodiesel process using new green catalyst. The obtained compounds were established using diverse spectroscopic data. These molecules were evaluated as catalyst in production process. The biodiesel yield was 93% in case of copper complex catalyst, while the amino acid catalyst give 96% yield. To get clear insight for catalysts properties, we measured surface activity and simulating the chemical reactivity using HF quantum calculation. The obtained data summarize that using the prepared catalyst lowering the biodiesel process cost through decreasing both process time and production cost.

In this study, mixed system containing manganese carbonate (MnCO3) and zinc glycerolate (ZnGly) was synthesized, and tested as solid catalyst for transesterification of soybean oil and biodiesel production. The samples of MnCO3/ZnGly before and after usage for transesterification process were characterized using different techniques: determination of basic strength, determination of specific surface area according to Brunauer-Emmett-Teller (BET), measuring the mass change using thermal gravimetric analysis (TGA), investigating the solid phase content and presence of different specific elements and groups by X-Ray diffraction (XRD), the Fourier transform infrared (FT-IR) spectroscopy, the scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS). The effects of different working parameters of transesterification were also investigated: temperature (438-458K), duration of transesterification (0-3.5h), methanol to oil molar ratio (12:1-36:1) and used amounts of catalyst (1-5 mass%). The reusability and stability of MnCO3/ZnGly were analyzed and obtained results showed that MnCO3/ZnGly exhibited a good activity with 100% TG conversion and 81.5% FAME yield with fresh catalyst, and can give 95-100% TG conversion and 62-78% FAME yield after 13 repeated use of same amount of catalyst without regeneration processes. Content of Mn and Zn in biodiesel and glycerol was analyzed by ICP-AAS after each reuse of catalyst.

In this paper, calcined river-snail shell was used as a novel solid base catalyst in the transesterification of soybean oil with methanol for biodiesel production. The calcined river-snail shell was characterized using field emission scanning electron microscope and X-ray diffraction. Effects of transesterification process variables were investigated. The results indicated that river-snail shell calcined at 800 °C catalyzed the transesterification of soybean oil for biodiesel with a yield over 98 % under the conditions including catalyst of 3.0% (w/w), a molar ratio of methanol/oil of 9:1, reaction time of 3 h, and reaction temperature of 65 °C. As a low-cost green catalyst, calcined river-snail shell could not only minimize the environmental wastes resulted from the solid shell, but also reduce the production costs of biodiesel.
