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 ...
Fixed-bed pyrolysis of Daphne (Laurus nobilis L.) seed
(Taylor & Francis Inc, 2003)
Fixed-bed slow pyrolysis experiments have been conducted on a sample of daphne seed to determine the effects of pyrolysis temperature, particle size, and heating rate on the pyrolysis product yields and chemical compositions. ...
Bio-oil from olive oil industry wastes: Pyrolysis of olive residue under different conditions
(Elsevier Science BV, 2005)
Olive residues were pyrolysed in a fixed bed reactor under different pyrolysis conditions to determine the role of final temperature, sweeping gas flow rate and steam velocity on the product yields and liquid product ...
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 ...
Pyrolysis of walnut shell in a well-swept fixed-bed reactor
(Taylor & Francis Inc, 2004)
Fixed-bed fast pyrolysis experiments have been conducted on a sample of walnut shell to particularly determine the effects of pyrolysis temperature, heating rate, particle size, and sweep gas flow rate on the pyrolysis ...
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 ...
