BACKGROUND Corn oil recovery and conversion to biodiesel has been widely adopted at corn ethanol plants recently. The US EPA has projected 2.6 billion liters of biodiesel will be produced from corn oil in 2022. Corn oil biodiesel may qualify for federal renewable identification number (RIN) credits under the Renewable Fuel Standard, as well as for low greenhouse gas (GHG) emission intensity cre...

Biodiesel, defined as the monoalkyl esters of vegetable oils and animal fats, is an alternative to conventional petroleum-based diesel fuel. Biodiesel has been prepared from numerous common vegetable oils or fats as well as new or less common feedstocks. Major issues facing biodiesel include several technical aspects such as cold flow and oxidative stability as well as availability of sufficien...

in order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. oil used in national engine species was 10w40 with dynamic viscosity 5.5 mpa.s at 140 °c (the working temperature). in order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by avl excite5.1 software. in th...

Viscosity of vegetable oil is considered a constraint for its use as an alternate fuel for Internal Combustion(IC) engines. In this experimental investigation, the viscosity of cottonseed oil (CSO), which is considered a potential alternate fuel, is reduced by blending it in different proportions with diesel, and its viscosity at various temperatures was analyzed and used as a fuel in a compres...

Biodiesel is a promising non-toxic and biodegradable alternative fuel in transport sector. Of all the biodiesel properties, specific gravity and viscosity are the most significant for the effects they have on the utilization of biodiesel fuels in unmodified engines. This paper presents models, which have been derived from experimental data, for predicting the specific gravity and dynamic viscos...

Out of various no edible oil resources, jatropha curcas oil is considered as a promising alternate fuel for CI engines. The present study describes the process used for production of degummed jatropha oil (DGJO) and jatropha methyl ester (JBD) The important fuel properties of DGJO and JBD were determined and compared with fossil diesel and jatropha oil. The degumming and trans esterification pr...

Background The production of fuels and chemicals from renewable resources is increasingly important due to the environmental concern and depletion of fossil fuel. Despite the fast technical development in the production of aviation fuels, there are still several shortcomings such as a high cost of raw materials, a low yield of aviation fuels, and poor process techno-economic consideration. In r...

This study demonstrates the co-hydrodeoxygenation of partially upgraded bio-oil (PUB) obtained from hydrothermal liquefaction pinewood, with rapeseed oil (RO) to produce bio-derived drop-in fuel. Enhanced miscibility PUB in RO showed high potential HTL for co-processing different refinery streams existing refineries. Co-processing experiments were conducted a continuous unit under processing co...

Biofuel is a prominent alternative fuel because of its environmental benefits and similar physiochemical properties to diesel fuel. This study investigated the impact of high quality refined, bleached and deodorized (RBD) coconut oil blends and fuel throttle setting on performance and exhaust emissions of diesel engine. The criteria regulated emissions and particulate-phase polycyclic aromatic ...

Biodiesel, the methyl ester of vegetable oil is a renewable, low environmental impact and potential as a green alternative fuel for diesel engine. High oil prices and growing concerns over climate change are driving investment and innovation in the biofuels sector as countries and industry increasingly look towards renewable bioenergy to replace fossil fuels. This study examines fuel properties...
