Production of biodiesel from waste cooking oil using MgMoO₄-supported TiO₂ as a heterogeneous catalyst

<p>Energy importers globally are gradually increasing. The maximum demand is for energy sources, especially for crude products. Biodiesel is eco-friendly and it is derived from vegetable oil, animal fat, waste cooking oil, and nonedible oil. In this study, waste cooking oil was used to make biodiesel with the help of a heterogeneous catalyst. Titanium dioxide doped with magnesium molybdate was used as a heterogeneous catalyst to make biodiesel by the alcohol mixture using the ultrasonication technique at 610^°C for 4 h. The catalysts were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Thermogravimetric analysis (TGA), and Energy-dispersive X-ray spectroscopy (EDAX) analysis.</p

Extraction of non-edible oil from <i>Catharanthus roseus</i> seeds and kinetics on oil extraction

<p>Today most of the countries in the world are the importers of energies. The largest demand occurred in the energy system, especially for petroleum and its products. Biodiesel is an environmentally friendly, renewable source, non-toxic and biodegradable matter. It contains monoalkyl esters of long chain fatty matters, and it is collected from vegetable oil, animal fats, algae, and non-edible oils. In this work, bio oil was extracted from <i>Catharanthus roseus</i> seed using Soxhlet apparatus. During the study of extraction, a better yield of bio oil 31.50% was obtained from a polar solvent like Methanol at 65°C, with the time of 3 h. The fuel parameters such as flash and fire point, cloud and pour point, and carbon residue 0.1% were studied. The parameters of physico-chemical properties and fuel properties are analyzed by AOCS and ASTM standard methods.</p
