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 …

utilization of environmentally friendly biofuels. Despite numerous government incentives and subsidies, biodiesel exports have … declined significantly over the years. This paper seeks to critically examine challenges afflicting the biodiesel industry in …, engine compatibility, fuel subsidies and crude oil prices were identified as the challenges hindering biodiesel development …

essential inputs for algae biodiesel production. In this paper, we assessed ethanol's life cycle greenhouse gas emissions and … fossil energy use produced in an integrated sugarcane and algae biorefinery where biodiesel replaces petroleum diesel for all … sugarcane bagasse is the sole source of energy for the entire facility. Glycerin produced from the biodiesel plant is consumed …

production of biodiesel under current and optimised conditions. An LCA (life cycle assessment) has been developed, comprising …

crystallization of biodiesel. The TAG (triacylglycerol) was found to be effective in depressing the crystallization onset of the … indicate that judicious loadings of TAGs which would target biodiesel's saturated FAMEs will have a substantial beneficial …

fuelled with diesel and biodiesel. Attention was focussed on both the fuel properties (cetane number, density) and engine …

boiler fueled with biodiesel and heating oil. In particular CO, SO2, NOx, particulate matter (PM), Polycyclic Aromatic … Hydrocarbons (PAH), Volatile Organic Compounds (VOC) and aldehydes emissions were examined. When using biodiesel, a strong … biodiesel were nearly 13 times less toxic than in the oil case; the formaldehyde, on the contrary, is nearly double for …

, Malaysia as an alternative feedstock for biodiesel production. This paper presents the results of the comprehensive technical … feasibility study for production of biodiesel from WCO feedstock. The results have shown feasibility of recycling WCO into … biodiesel that is compliant with international fuel standard ASTM D6751. The study has given an indication on the appropriate …

This study investigates the effect of ambient oxygen concentration on biodiesel and diesel spray combustion under … higher ambient oxygen concentration conditions. OH* chemiluminescence and NL contours indicate that biodiesel may experience … a longer premixed-combustion duration. The 18% ambient O2 condition works better for biodiesel than diesel in reducing …
