Plastics have become an indispensable part of our daily life. Due to its non biodegradable nature it cannot be easily disposed off. Pyrolysis is a tertiary recycling method which can convert plastics into valuable petroleum resources. In this work, pyrolysis of waste high density polyethylene (HDPE) plastic was carried out in a fixed bed reactor heated for a final temperature of 500°C under a heating...
Nowadays the electricity demand in non-interconnected areas of Colombia (ZNI in Spanish) is high and usually scattered throughout the Colombian territory, in this way its connection to the national distribution grid is infeasible, because of its remoteness and difficult access. To ensure the energy supply in the ZNI diesel generators are used, however the generation with diesel is expensive, and creates...
The article describes computational methods for determination of cetane index of diesel fuels; the most accurate method is established. On the basis of the experimental data, equations for calculation of the low-temperature properties of diesel fuels were developed. These equations allow to calculate pour point and cold filter plugging point of diesel fuels with an error not exceeding 1 °C.
The symbiotic relationship between internal combustion engines (Otto and Diesel) and petroleum-derived fuels (gasoline and Diesel oil) has characterized the entire road traffic scene for more than 100 years. To date, the increasingly stringent demands on vehicles and engines could be complied with by harmonizing the further development of engines and fuels. According to the current state of the art,...
In this paper we try to export a regression equation which describes the variation of humidity of Diesel fuel with time. A hydrophilic polymer is used to eliminate humidity from diesel fuel and the regression analysis shows that the maximum decrease of humidity in an hour it is of about ˜ 35%.
Higher heating value (HHV) is one of the important parameter in performance modeling of thermal systems. The HHV of liquid fuels is determined experimentally, which is time consuming and expensive. From literature survey it is observed that the HHV of few fuel oils is a function of viscosity. The authors have deduced a correlation of HHV and viscosity of diesel fuel. This paper discusses development...
Monitoring the boiling point of a diesel fuel is an important step to understand the characteristics of the diesel fuel. This study evaluated the feasibility of adaptive linear neuron (Adaline) as a predictive model to predict the boiling point of diesel fuel based on near infrared spectrum. The parameters of learning rate and training cycle that involved in the optimization process were examined...
The paper presents materials of the investigation into the single-phase process of desulfuring of the diesel fuel with the use of the microwave electromagnetic energy process as an initiator at a temperature not exceeding 100 °C. Aluminum, zinc, copper and iron ions were used as chemisorbents, which enable to obtain the residual sulfur content at the level of the EURO-4 standard, and with the use...
To characterize diesel fuel for use and thereby establish a framework of definition and reference, various classifications are used in different countries—within the grades, there are variations in the specifications for the physical and chemical compositions of the fuel. Diesel fuels originally were straight‐run products obtained from the distillation of crude oil. One of the test methods resolves...
An experimental investigation has been conducted to study diesel fuel reforming by a recirculation type electrohydrodynamic atomization system (REHDA). The fuel in the EHD atomization system was injected through a hollow tube electrode that was powered using a high voltage pulse power supply. A hollow ring on the ceramic holder for the hollow tube served as the ground electrode. Experiments were performed...
Biodiesel has been gaining increased attention as a nontoxic, biodegradable and renewable new green alternative diesel fuel. Production of biodiesel can be synthesized by chemical or by lipase methods, while lipase method has more advantages compared to chemical synthetic method. In this article, the microbial strains with activity of lipase were isolated from long time oil-contaminated soil and strain...
In this paper, a novel biodiesel named rapeseed oil monoester of ethylene glycol monomethyl ether has been developed, which has one more ester group than traditional biodiesel. It was synthesized and structurally identified through FT-IR, 1H NMR analyses. Engine test results show that when atested diesel engine is fueled with this biodiesel in place of 0#diesel fuel, engine-out smoke emissions can...
Oxidative desulfurization of real diesel was carried out at mild conditions( atmospheric pressure) in presence of phosphotungstic acid/semi-coke catalysts. The effects of two phase volume ratio, reaction temperature, on the efficiency of desulfurization were investigated. meanwhile, treatment of model solution of cyclohexane containing BT, DBT and 46-DMDBT with our ODS system at 80°C in 1h.
With the great development of automobile industry and road system, the pollution of automobile exhaust becomes more and more serious, also mercury pollution. Burning mercury-rich fuel oil was thought the essence of pollution source. It's found that elemental mercury (Hg0), divalent reactive gaseous mercury (RGM), and particulate mercury (Hg (p)) from gasoline. The content of mercury is LPG>;gasoline>;...
The effects of Methyl-Tetra-Butyl-Ether (MTBE), as an additive, on the performance, combustion and the emission characteristics of a compression ignition (CI) engine are investigated experimentally. The experimental set-up consists of a diesel engine coupled with an eddy current dynamometer, AVL Di-gas analyser, AVL smoke meter and a data acquisition system is used. The di-gas analyzer is used to...
The study mainly deals with the causes of air pollution in Gulbarga related to buses. Particularly it focuses on the suggestion to curb the vehicular pollution by the use of biodiesel. The pollution loads have been calculated and compared by considering usage of the biodiesel in place of conventional diesel fuel in buses. For the purpose of this study, the three depots of the NE-Karnataka Road Transport...
Expectation on the hydrogen economy has been drawing diverse applications of hydrogen and synthesis gas. From transport, environmental issues to chemical industries, One of the representative examples is on board reforming of diesel fuel. Synthesis gas from reforming of fuel can be used as reducing agent for NOx reduction process. Also the reformate gas can be supplied to engine during engine start-up...
One of the most promising applications for wind energy is its use in electric power systems for remote isolated locations. Currently most remote and isolated communities depend on conventional diesel fuel for their electricity supply. Diesel generations in these locations are expensive mainly due to the escalating fuel costs. The associated maintenance costs and transportation costs are also relatively...
Though experiment of the waste edible oil fuel, life cycle assessment methods of the waste edible oil fuel and diesel fuel were introduced in the process of preparation and combustion. The results showed that the petroleum diesel oil of the blended fuel proportion reduce, contamination index value also reduced except eutrophication potential. The petrochemical diesel oil system is more serious than...
Mineral processing is one of the most energy intensive industrial operations with important direct emissions given by the Diesel fuel used in mining equipment like haul trucks for mineral transportation and indirect emissions generated by the use of electrical energy in grinding mills, slurry pumps and high-current rectifiers. Therefore, there is a challenge for improving the efficiency of energy...
