Biodiesel has become an alternative fuel to substitute conventional fuel, yet challenges remain, particularly concerning water content. The presence of water in biodiesel can negatively impact engine spray and combustion properties and may lead to damage storage tanks. To address this issue, a phase-shift-based capacitive sensor was developed in this study to accurately measure water concentration in biodiesel. The sensor, designed with a semicylindrical electrode on a glass tube, is integrated with a signal conditioning circuit and the Digilent Analog Discovery module, allowing for real-time data analysis and enhanced sensitivity in detecting low concentrations of water concentration in biodiesel. The experimental results demonstrated a direct correlation between capacitance values and phase shift, with higher capacitance leading to more significant phase shifts. A Bode plot and simulation analysis, utilizing the transfer function, validated these experimental conditions, confirming t.....

This study investigates the thermal conversion of waste coral and its utilization as a heterogeneous catalyst for biodiesel production from soybean oil. In this work, waste coral is calcined at varied temperatures of 800, 900, and 1000°C, and the effect of the calcination temperature on the physicochemical character of the solid is evaluated through Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and basicity measurement. The results show that the higher temperature facilitates the conversion of CaCO3 of the aragonite and calcite phases in raw waste coral into CaO, achieving a complete conversion at the temperature of 1000°C. Thermal conversion influences the increased surface basicity of the solid, which is associated with the higher activity for biodiesel production. Further studies on the obtained CaO as a catalyst demonstrate the catalyst dosage and the methanol-to-oil ratio as significant factors for fatty acid methyl ester production. T.....
