Vegetable oil derived fuels for diesel engines are becoming important as alternative to petroleum diesel fuels due to their environmental friendliness and availability. Ignition quality in compression ignition (CI) engines is influenced by thermal characteristics and fuel properties. In this study, the effects of vegetable oil transesterification and vegetable oil-1-butanol-diesel blend on fuel...

Very Low Sulfur Fuel Oils (VSLFO, <0.5% S) are a new class of marine fuel oils, introduced to meet recent International Maritime Organization regulations. The MV Wakashio was reported have released 1000 t VLSFO when it grounded on reef in Mauritius 25th July 2020. A field sample oily residue contaminating the Mauritian coast collected 16th August 2020 and compared with oil. Both oils were analy...

A fixed bed pyrolysis has been designed and fabricated for obtaining liquid fuel from mustard de-oiled cake. Thermal pyrolysis of mustard deoiled cake were carried out in a semi batch reactor made up of stainless steel at temperature range from 450 0 C to 600 0 C and at a rate of 150C /min to produce bio-fuel. The maximum yield of oil was 51% on wt. % basis for mustard de-oiled cake, it was obt...

Emissions from aircraft engines represent a highly complex and important issue, which is related to the risk to human health. Particles emitted in urban areas and in the vicinity of airports affect air quality and have a particularly negative impact on airport workers. The development of measurement techniques and the methodology for evaluating exhaust emissions have allowed for the elaboration...

it has been known for years that microbial surface active agents have a wide range of applications not only in oil spill environment but also in many industries. their properties including: (i) changing surface active phenomena, such as lowering of surface and interfacial tensions, (ii) wetting and penetrating actions, (iii) spreading, (iv) hydrophylicity and hydrophobicity actions, (v) microbi...

The advances in industrial technology have led to a major rise the amount and forms of residue, especially during processing agricultural products. With paradigm shift towards renewable energy sustainability, there is much emphasis on biomass around world which generates an immense volume residues yearly. These are burgeoning issues because they not effectively managed utilized. Hence, one solu...

This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuel published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from a...

Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8...
