Hazelnut Kernel Oil Case Study

Amazing Essays
Metin GUMUS et al.,[1]. In this study, hazelnut (Corylus avellana L.) kernel oil was tested and studied as an alternative fuel in diesel engines. The hazelnut kernel oil is made to undergo transesterfication process for reducing the viscosity of the oil. The processed hazelnut kernel oil possesses all the properties of biodiesel used in the diesel engine. The suitable transesterification reaction conditions for hazelnut kernel oil are volumetric ratio of the reactants in the ratio 1:5, reaction temperature 65 ◦C, potassium hydroxide is used as a catalyst in this process. This increased the Brake Thermal Efficiency (BTE) and slightly reduced the Brake Specific Fuel Consumption (BSFC) for Lower HOME content blends B5 and B20.The maximum BTE …show more content…
Madyira et al.,[5]. In This paper, Daniel M. Madyira reports on analysis and study of using sunflower oil as an diesel blends for the production of biodiesel as alternatives to diesel fuel. Biofuels are now recognized as an alternative viable option. Some of the difficulties of using biodiesel in conventional diesel engines are their higher viscosity, acidity levels that influences the structural integrity of the engine and low density which results in low calorific value and leading to incomplete combustion. In this process, in the presence of Sodium hydroxide catalyst and methanol batch transesterfication is applied to sunflower oil for the production of biodiesel. The biodiesel was characterized and then conducted using Nuclear Magnetic Resonance (NMR), bomb calorimetry, sulphur content tests and Gas Chromatography (GC) and acidity and flash point …show more content…
Srithar et al.,[7]. In this paper, Srithar proposes that Biodiesel produced from vegetable oils has considered as a promising alternate fuel and also says that the performance study and analysis of two biodiesels from mustard oil and pongamia pinnata oil and they are blended at various mixing ratios with diesel. The result of performance of the dual biodiesel in engine and exhaust emissions were studied in a single cylinder, air cooled, direct injection and high speed diesel engine at different engine loads with a constant engine speed of 3000 rpm. The emissions of smoke opacity, nitrogen oxides and hydro carbon of dual biodiesel blends were higher when compared to that of diesel. But the exhaust gas temperature when compared to that of diesel was lower with dual biodiesel. From the experimental study results, the thermal efficiency and mechanical efficiency of Blends A were slightly higher than the diesel. Blend B and Blend C are very closer when compared to the diesel values. The Brake Specific Fuel Consumption values of dual biodiesel blends were in accordance to that diesel. Some blends produced slightly lower CO and CO2 when compared to that of diesel. Thus it produces a considerable advantage of diesel while using the dual biodiesel

    Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1].

    The purpose of this stage is mixing the generated Isobutylene that comes from the Oleflex unit with the excess amount of methanol manufactured by QAFAC to produce MTBE. Two isobutylene spheres (V 3101, V 3102) are designed to store 2,400 m3 other than storing requirements. These spheres can receive isobutylene after shutdown in the downstream and they are continuously charge and receive Isobutylene in initial startup and normal shutdown. The feed passes through highly acidic ion exchange (V 2302), low temperature and relatively high pressure, these conditions are required to mix Isobutylene with methanol to produce MTBE. MX 2301 is the Mixer in this stage of the process that mixes isobutylene that comes from (V 3101, V 3102) with Methanol from Methanol drum (V 2303).…

    Addition-ally, ABE29.5W0.5 produced a lower NOx and CO and also increased UHC, but showed de-creased NOx and CO emissions compared to ABE30 and pure gasoline. Another study done by the same authors [226] also evaluated the effect of water-containing ABE-gasoline blends (ABE30, ABE85, ABE29.5W0.5 and ABE29W1) on combustion, performance, and emission characteristics of SI engine. In addition, ABE29W1 was compared with gasoline under vari-ous equivalence ratios and engine loads. The results revealed that ABE29W1 generally had a higher engine torque (3.1–8.2%) and lower CO (9.8–35.1%), UHC (27.4–78.2%) and NOx (4.1–39.4%) than those of gasoline. Study has investagated by [227] that reported a comparative study of high-alcohol-content gasoline blends in SI engines.…

    The present work is aimed at the improvement of performance, combustion and emission characteristics of a rice bran biodiesel-biogas run dual fuel diesel engine through adjustment of compression ratio (CR), and injection timing (IT) of pilot fuel. For experimentation, a single cylinder, direct injection, variable compression ratio diesel engine is converted into a dual fuel diesel engine by connecting a venturi gas mixer at the inlet manifold. A set of combinations comprising of CRs of 17, 17.5 and 18, and ITs of 23⁰, 26⁰, 29⁰ and 32⁰ before top dead centre (BTDC) at different loading conditions are considered. The combination of IT = 32⁰ BTDC and CR = 18 is found to produce a maximum brake thermal efficiency of 25.88% and a liquid fuel replacement…

    The brake thermal efficiency of engine running on SVOs is found to be lower, whereas the brake specific fuel consumption is higher compared to diesel [1-3]. With regard to exhaust gas emissions, some studies reported that SVOs increase the production of CO, CO2 and unburned HC emissions, while NOx is found to be reduced compared with diesel [2, 4]. The higher viscosity and low volatility of SVOs are reported to be the cause of inferior performance, thus preheating the oil before injection showed an increase in performance and emissions reduction. It has been observed that preheating increases the brake thermal efficiency and reduces the emissions compared to unheated SVOs, whereas preheating improves the atomisation and spray characteristics bringing the properties of SVOs closer to diesel [5,…

    Liquefaction and gasification in supercritical water (SCW) are two processes for transferring substances into liquid and gaseous fuels, which is special for high moisture substances6. Supercritical water, which is serve as the solvent and the reactant in these reactions, mainly decreases mass transition restrictions in ambient condition water; therefore, it helps to accelerate the chemical reactions largely9. However, the vaporization of water along with raw materials is required by traditional pyrolysis and gasification method to convert high-moisture substances, which causes lowering thermal efficiency2. Recent researches have shown that SCW method of gasification produces enormous amount of tar waste water, which have toxic substances such…
