The production of gas via bio-oil gasification, which would act as a bridge between bio-oil and transportation fuels, has been increasingly concerned. Bio-oil gasification was performed by using air - steam as gasifying agents. The effects of two important influential factors (steam to bio-oil ratio and gasifier temperature) on the quality of the product gas (gas composition, H2: CO, CO: CO2, tar...
Biodiesel production from waste cooking oil using calcined Mg/Al HT (hydrotalcite) as heterogeneous catalyst was investigated. This study describes the calcined Mg/Al HT prepared under optimal conditions to catalyse waste cooking oil for biodiesel preparation and proposes a plausible catalysis mechanism. The catalysts were characterised by Fourier Transform-Infrared, X-ray diffraction, Thermal Gravity...
In this study, we produced biodiesel by utilising waste cooking oil as a raw material, unrefined methanol produced by a chemical plant as a transesterification agent and sodium hydroxide as a catalyst. The yield and heating value of the biodiesel produced with unrefined methanol were respectively 1.09% and 0.23 MJ/kg higher than those of the biodiesel prepared with pure methanol. The biodiesel characteristics...
