Kinetics of esterification of acetic acid with n-amyl alcohol in the presence of Amberlyst-36
(Elsevier Science BV, 2011)
The kinetics of esterification of acetic acid with amyl alcohol has been studied in the presence of Amberlyst-36 in its H(+) form in a batch reactor. Experimental findings showed that the reaction is controlled by chemical ...
Fast pyrolysis of sunflower-pressed bagasse: Effects of sweeping gas flow rate
(Taylor & Francis Inc, 2002)
Sunflower (Helianthus annus L.)-pressed bagasse pyrolysis experiments were performed in a fixed-bed tubular reactor. The effects of nitrogen flow rate and final pyrolysis temperature on the pyrolysis product yields and ...
Production and characterization of pyrolysis oils from Euphorbia macroclada
(Taylor & Francis Inc, 2004)
In this work, Euphorbia macroclada were pyrolyzed in a laboratory-scale fixed bed reactor. The influence of final pyrolysis temperature, heating rate, and pyrolysis atmosphere on the product Yields was investigated. Pyrolysis ...
Kinetics study of esterification of acetic acid with isobutanol in the presence of amberlite catalyst
(Elsevier Science BV, 2003)
Kinetic data on the esterification of acetic acid with isobutanol have been obtained from both the uncatalyzed and heterogeneously catalyzed reactions using a stirred batch reactor in dioxane. The equilibrium constant, ...
The effect of pyrolysis atmosphere on bio-oil yields and structure
(Taylor & Francis Inc, 2017)
A food industry waste, almond shell, was pyrolyzed under three different environment static, nitrogen, and steam to produce bio-oil and its derivatives. The oil yield obtained at pyrolysis temperature of 600 degrees C was ...
Optimization of structural combinations on the performance of a PEMFC's MEA
(Elsevier Science BV, 2008)
In this study, the Taguchi method was applied to determine optimum structural combination of a membrane electrode assembly (MEA) in obtaining maximum power density of a PEMFC. Performance measure analysis was also followed ...
Comparison between the "slow" and "fast" pyrolysis of tobacco residue
(Elsevier Science BV, 2007)
In this study, the trends in yields and product compositions of slow pyrolysis and fast pyrolysis were determined and compared with each other. Slow pyrolysis of tobacco residues with particles of between 0.425 and 0.850 ...
Pyrolysis of Peach Pulp: Effect of Chemical Additives
(Taylor & Francis Inc, 2014)
Peach pulp and impregnated sample have been investigated as an alternative feedstock to obtain fuels and chemicals. The effect of a series of operation variables was studied. The maximum oil was obtained as 23.24% at the ...
Optimization of parametric performance of a PEMFC
(Pergamon-Elsevier Science LTD, 2007)
In this study, the Taguchi method was applied to determine optimum working conditions in obtaining maximum power density of a PEMFC. Performance measure analysis was also followed by performing a variance analysis, in order ...
Sonochemical synthesis and loading of PbS nanoparticles into mesoporous silica
(Elsevier Science BV, 2018)
A sonochemical method was used for simultaneous synthesis and loading of lead sulfide (PbS) nanoparticles into mesoporous SBA-15 (Santa Barbara Amorphous). In this study, the effect of different loading ratios (30, 45, 60, ...
