Influence of an oxygenated additive on emission of an engine fueled with neat biodiesel
Emissions Nano-fluid Turbulence
2018/4/2
Biodiesel obtained from mustard seed is found to be a promising alternative for petroleum diesel fuel owing to its similarity in physical and chemical properties. In this work, TiO2 nano-fluid which a...
Influence of Degree of Unsaturation of Fatty Acid Methyl Ester on Oxidative Deterioration Behavior of Model Biodiesel Mixed Diesel Fuel
Biodiesel Fatty acid methyl ester Oxidation stability Sludge Sulfur compound
2010/9/8
In order to investigate the influence of fatty acid methyl ester (FAME) on oxidative deterioration behavior of biodiesel mixed diesel fuel, FAME/tetradecane mixtures were prepared as model biodiesel/d...
Influence of water on yields and isotopic fractionations of gas hydrocarbons generated from oil cracking
crude oil pyrolysis experiment water gas yield carbon and hydrogen isotope
2017/8/9
Few investigations have been made to discuss the influence of water on the yields and carbon and hydrogen isotopic ratios of gas hydrocarbons generated from oil cracking although water occurs in oil r...
Influence of Preparation Factors on Ca/P Ratio and Surface Basicity of Hydroxyapatite Catalyst
Hydroxyapatite Calcium/phosphorus ratio Basicity Basic site density
2009/8/4
We aimed at precision control of the basicity of hydroxyapatite (Ca10(PO4)6(OH)2; HAP) and paid attention to four key factors in the synthesizing process—the solution's Ca/P ratio, pH, temperature and...
Influence of Ultraviolet Absorbers on Decomposition of Hydroperoxide by Hindered Amine Light Stabilizers
Hydroperoxide Decomposition HALS UVA Synergism
2009/8/4
The interaction between hindered amine light stabilizers (HALS), and ultraviolet absorbers (UVA) was investigated, in order to clarify the reason why they generally show synergism, although UVA belong...
Control of Macropore Structure of Hydrocracking Catalyst by Silica-alumina Particle Size and Influence on Hydrocracking Activity and Middle Distillate Selectivity
Hydrocracking Diffusivity Macropore structure Particle size Middle distillate selectivity
2009/7/28
Hydrocracking (HC) catalysts consisting mainly of silica-alumina and a small amount of ultra stable Y type (USY) zeolite were prepared with silica-alumina powders of different mean particle sizes, an...
Influence of Catalyst Support and Reaction Gas on Decomposition of Methane over Ni Catalysts
Methane decomposition Nickel catalyst Carbon nanotube Glycothermal method
2009/7/24
Nickel-catalyzed decomposition of methane into carbon and hydrogen was examined using a thermogravimetric apparatus. The Ni catalyst supported on zirconia synthesized by the glycothermal method gave ...
Influence of Corrosion Products on Magnetic Flux Leakage Signals in Inspection of Far-side Metal-loss Defects in Oil Storage Tank Bottom Floors
Non-destructive testing Magnetic leakage field Oil storage tank
2009/7/24
Magnetic flux leakage testing (MFLT) is a reliable inspection method for far-side metal loss type flaws. Corrosion products of ferromagnetic substances are generated in wet environments, so may affe...
An influence of acetic acid on the carbon dioxide corrosion of 13 % Cr tubing in Minami-Nagaoka gas field
Minami-Nagaoka gas field 13 %Cr steel tubing localized corrosion
2009/5/8
Localized corrosion was found on inner surfaces of 13 %Cr steel tubing at shallow depths in deep, hot corrosive Minami-Nagaoka gas wells. Judging from the high penetration rates of corrosion pits, fa...
