Abstract
Abstract Transesterified vegetable oils (VOs) are promising alternative diesel fuel. Waste VOs are cheap and renewable but currently disposed of inadequately. In this work, waste palm oil was transesterified under various conditions. H2SO4 and different concentrations of HCl and ethanol at different excess levels were used. Higher catalyst concentrations (1.5–2.25 M) produced biodiesel with lower specific gravity, γ, in a much shorter reaction time than lower concentrations. The H2SO4 performed better than HCl at 2.25 M, as it resulted in lower γ. Moreover, a 100% excess alcohol effected significant reductions in reaction time and lower γ relative to lower exces...
