Microwave Heating Application To Produce Dehydrated Castor Oil
(American Chemical Society, 2011)
Dehydrated castor oil (DCO) is the best known and most widely used of all the oils commonly termed "synthetic" drying oils. DCO imparts good flexibility, rapid drying, excellent color retention, and water resistance to ...
Alkali catalyzed transesterification of cottonseed oil by microwave irradiation
(Elsevier Sci LTD, 2007)
In this work microwave assisted transesterification of cottonseed oil was carried out in the presence of methanol and potassium hydroxide (KOH). Parametric studies were done to investigate the optimum conditions (catalyst ...
Fatty acids of the seeds of Origanum onites L. and O-vulgare L.
(Springer Heidelberg, 2004)
Seed oils of Origanum onites L. from the Antalya and Mugla regions and O. vulgare L. from the Kirklareli region of Turkey were extracted with hexane in a Soxhlet apparatus. The oil yields were 14.1-20.0 and 18.5%, respectively. ...
Comparision of real waste (MSW and MPW) pyrolysis in batch reactor over different catalysts. Part I: Product yields, gas and pyrolysis oil properties
(Elsevier Sci LTD, 2013)
Pyrolysis of municipal solid waste (MSW) and municipal plastic waste (MPW) have been investigated in batch reactor at 500, 550 and 600 degrees C both in absence and presence of catalysts (Y-zeolite, beta-zeolite, equilibrium ...
Equilibrium, kinetic, and thermodynamic studies of the adsorption of Fe(III) metal ions and 2,4-dichlorophenoxyacetic acid onto biomass-based activated carbon by ZnCl2 activation
(Elsevier Science BV, 2017)
This study investigated the preparation of activated carbon from low-cost biomass as precursor and the using of obtained activated carbon for the removal of Fe(III) and 2,4-D pollutants from model solution. The different ...
Thermogravimetric characteristics and kinetics of scrap tyre and Juglans regia shell co-pyrolysis
(SAGE Publications LTD, 2014)
The degradation kinetics of Juglans regia shell, scrap tyre and their blends were investigated using a thermogravimetric analysis method. Experiments were performed under dynamic conditions and a nitrogen atmosphere in the ...
The production and evaluation of bio-oils from the pyrolysis of sunflower-oil cake
(Pergamon-Elsevier Science LTD, 2002)
Sunflower (Helianthus annus L.)-oil cake pyrolysis experiments were achieved in a fixed-bed tubular reactor. The effects of nitrogen flow rate and final pyrolysis temperature on the pyrolysis product yields and chemical ...
The Effects of Different Catalysts on the Pyrolysis of Thistle, Onopordum Acanthium L.
(Taylor & Francis Inc, 2013)
Fixed-bed fast pyrolysis experiments have been conducted on a sample of thistle, Onopordum Acanthium L. The experiments were performed in a fixed-bed tubular pyrolysis reactor to investigate the effects of sweeping gas ...
Biodiesel production from waste frying oils: Optimization of reaction parameters and determination of fuel properties
(Pergamon-Elsevier Science LTD, 2012)
Alkali-catalyzed transesterification of waste frying oils (WFO) was carried out in various conditions to investigate the effects of catalyst concentration, reaction time, methanol/oil molar ratio, reaction temperature, ...
Flue gas desulfurization by citrate process and optimization of working parameters
(Elsevier Science Sa, 2010)
In this study, model flue gas was bubbled into 0.25 L tribasic sodium citrate (TSC) solution being in 0.5 L glass absorber to remove its SO2 content. Size of gas bubbles, absorption temperature, gas flow rate, solution ...
