Comparison of performance and emissions of diesel fuel, rapeseed and soybean oil methyl esters injected at different pressures

The Environmental Impacts and Allocation Methods Used in LCA Studies of Vegetable Oil-Based Bio-diesels

“…Feedstocks of Bio-diesel First Generation Plant Oil Based Bio-diesel Feedstocks Biodiesel produced from palm oil [6], soybean [7], rapeseed [8] and sunflower [9] is considered as first generation bio-diesel feedstock. These crops were initially used in bio-diesel fuel production for the first time.…”

Sustainability Study on Heavy Metal Uptake in Neem Biodiesel Using Selective Catalytic Preparation and Hyphenated Mass Spectrometry

“…On the other hand, lower measured concentrations of other toxic elements (Sb, Th) were recorded with KOH treatment (Figure 5). These deleterious elements can be released into the atmosphere as exhaust fumes from biodiesel combustion [20,29] and could also migrate into the soil and water table, especially if poor quality biofuel is dumped. Sustainable development is the key factor in producing biofuel and it is necessary to guard against the threat of contamination.…”

“…It is well known that abnormal metal content of biofuel is deleterious to the environment [17][18][19][20][21][22][23] as well as engines [24][25][26][27][28] and could spawn costly demetallization processes. It has been previously reported by the authors that trace metals and heavy elements in biodiesel play a multiple role in diminishing the performance of machinery [29].…”

“…It is favored for its low toxicity, high degradability, general reduction of engine emissions and its role in sustainable development [17][18][19][20][21][22][23][24][25][26]. Reduction in CO 2 emissions is more pronounced for biodiesel from vegetable oil and it has emerged that biofuel production from non-edible biomass is more economical and more compatible with regular diesel fuel [19][20][21][22][23]. Our biofuel was derived from neem oil using a combination of homogeneous (NaOH, KOH) and heterogeneous (CaO) catalysts [30][31][32].…”

A critical review of the applicability of biodiesel and grass biomethane as biofuels to satisfy both biofuel targets and sustainability criteria

“…The reduction of exhausts are more effective for tallow biodiesel than rape seed biodiesel, because the high SFA content in tallow helps to improve the combustion efficiency through the increased cetane number [48,[50][51][52].…”
