The consumption of oil fuel in Java shows that more than 70% of oil fuel is consumed in metropolitan cities, 14.2% is consumed in big cities, and 15.67% is consumed in medium cities. The variables of urban transport system powerfully influencing on oil fuel consumption are motor vehicles and roads. The influence of city typology (the number of population and) on oil fuel consumption is greater ...
Due to limited energy resources, high energy demand and constrict emission norms led the researchers to find alternative fuel for IC engines. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Many alternative fuels have been developed and commercialized like alcohols, biodiesel, LPG, CNG etc. pyro...
Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...
various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...
A three-phase nonisothermal heterogeneous model for describing the hydrotreating reactions in a trickle-bed reactor with complete catalyst wetting was solved. It includes correlations for determining solubility data, mass-transfer coefficients, and properties of the compounds under operating conditions. The model, based on the two-film theory and mass-transfer resistance at the gas-liquid and l...
A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by conventional oil recovery methods. Further downstream, the petroleum industry is facing challenges to remove sulfur, metal, nitrogen as well as undesirable organic compounds from the crude. Conventional secondary recovery methods such as water and gas injections helped to increase the productivity of the well...
The petrochemical industry is traditionally a high energy consumption industry, thus saving in this of great significance terms trying to achieve the national goal “carbon-peak and carbon neutrality” China. Diesel one main products enterprises. diesel hydrotreating (HDT) unit relatively due reaction temperature pressure HDT reactors. In order further explore units under different operating cond...
In the present study, the high viscosity of the jatropha curcas oil was decreased by preheating. The effect of fuel inlet temperature on performance of diesel engine is evaluated. A single cylinder, four stroke, constant speed, air cooled, direct injection diesel engine developing a power output of 3.7 kW at 1500 rev/min typically used in agricultural sector was tested using neat jatropha oil a...
