Adsorptive removal of phenol from aqueous solutions on activated carbon prepared from tobacco residues: Equilibrium, kinetics and thermodynamics
(Elsevier Science BV, 2011)
This study consists of producing high surface area activated carbon from tobacco residues by chemical activation and its behavior of phenol removal from aqueous solutions. K(2)CO(3) and KOH were used as chemical activation ...
Microwave assisted transesterification of waste frying oil and concentrate methyl ester content of biodiesel by molecular distillation
(Elsevier Sci LTD, 2013)
In this study, microwave assisted transesterification of waste frying oil was carried out in the presence of sodium methoxide (NaOCH3). Parametric studies were performed to investigate suitable reaction conditions such as ...
Use of sesame stalk biomass for the removal of Ni(II) and Zn(II) from aqueous solutions
(Iwa Publishing, 2012)
In this study an agricultural residue, sesame stalk, was evaluated for the removal of Ni(II) and Zn(II) metal ions from aqueous solutions. Biosorption studies were carried out at different pH, biosorbent dosage, initial ...
Optimization of biodiesel production from castor oil using factorial design
(Elsevier Science BV, 2013)
In this study, optimization of biodiesel production from castor oil using full factorial design was investigated. The biodiesel production was carried out in a batch laboratory scale reactor by alkaline-catalyzed ...
Thermal decomposition behavior of tobacco stem Part II: Kinetic analysis
(Taylor & Francis Inc, 2016)
As a continuation of the previous study on the thermal degradation behavior of tobacco stem, this work is focused on the kinetics of pyrolytic decomposition. Thermogravimetric analysis of tobacco stem samples was conducted ...
Methanol to hydrocarbons over large cavity zeolites: Toward a unified description of catalyst deactivation and the reaction mechanism
(Academic Press Inc Elsevier Science, 2010)
The reaction mechanism for the conversion of methanol to hydrocarbons over three large cavity zeolites, H-beta, H-MCM-22, and H-mordenite, has been investigated. (13)C methanol was co-reacted with (12)C benzene to study ...
Combined effect of a plasticizer and carvacrol and thymol on the mechanical, thermal, morphological properties of poly(lactic acid)
(Wiley, 2018)
In this study, the effects of the monotherpenic phenol concentration on the properties of biocomposites containing plasticized poly(lactic acid) (PLA) with acetyl tributyl citrate (ATBC) were investigated. The monotherpenic ...
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 ...
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 ...
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 ...
