Bio-oil production from pyrolysis and steam pyrolysis of soybean-cake: product yields and composition
(Pergamon-Elsevier Science LTD, 2002)
The slow pyrolysis of soybean cake in a fixed-bed reactor was investigated under three different atmospheres: static, for determining the effects of pyrolysis temperature and particle size, nitrogen and steam. The liquid ...
Production of biocrudes from biomass in a fixed-bed tubular reactor: product yields and compositions
(Elsevier Sci LTD, 2001)
Fixed-bed pyrolysis in a tubular reactor were conducted on three biomass samples, Euphorbia rigida, sunflower (Helianthus annuus L.) pressed bagasse and hazelnut (Corylus avellana) shells, to determine the possibility of ...
Evaluation of the role of the pyrolysis temperature in straw biomass samples and characterization of the oils by GUMS
(American Chemical Society, 2008)
The aim of this study is to investigate the variation of thermal conversion of agricultural wastes in a fixed bed reactor with temperature and elucidating the chemical structure of oil products formed during the process. ...
Optimization of desilication parameters of low-silica ZSM-12 by Taguchi method
(Elsevier Science BV, 2019)
Zeolite ZSM-12 was synthesized by a direct hydrothermal method and subsequently desilicated by alkaline treatment under different conditions. Changes in the properties of the zeolite samples were investigated by XRD, ...
Nano-12-Tungstophosporic Acid Cesium Salt Synthesized by Ultrasound as Catalyst for Alkylation of Benzene with dec-1-ene
(Walter De Gruyter GMBH, 2017)
Nano 12-tungtophosphoric acid cesium salt (Cs-TPA) was synthesized under ultrasonic irradiation in nanoscale. The obtained catalyst was characterized by various methods. These analyzes indicate that the chemical structure ...
Optimization of bio-oil production using response surface methodology and formation of polycyclic aromatic hydrocarbons (PAHs) at elevated pressures
(Elsevier Science BV, 2016)
This paper aims at the optimization of bio-oil yield obtained from poplar sawdust pyrolysis. A response surface methodology was carried out to optimize the experimental conditions. The factors investigated were temperature, ...
Influence of Zinc Oxide on Thermoplastic Elastomer-Based Composites: Synthesis, Processing, Structural, and Thermal Characterization
(Wiley-Blackwell, 2016)
It was aimed to investigate how thermal conductivity and stability properties of synthesized thermoplastic elastomers were influenced by zinc oxide (ZnO) additives which differed in size and surface treatment. ZnO particles ...
Kinetic Study of the Formation of Isopropyl Alcohol by Transesterification of Isopropyl Acetate with Methanol in the Presence of Heterogeneous Catalyst
(American Chemical Society, 2014)
The kinetics of the transesterification of isopropyl acetate with methanol to methyl acetate and isopropyl alcohol catalyzed by Lewatit MonoPlus S100 H+ was studied in a pressurized batch reactor. In the temperature range ...
Antioxidant and free radical scavenging activities of Rhus coriaria and Cinnamomum cassia extracts
(Akademiai Kiado, 2003)
Antioxidant and free radical scavenging activities of the extracts of sumac (Rhus coriaria) fruits and cassia. (Cinnamomum cassia) cortex were studied. Plant samples were extracted with methanol:water (80:20) and an aliquot ...
Removal of Dye Stuffs from Waste Water: Electrocoagulation of Acilan Blau Using Soluble Anode
(1992)
An attempt was made to remove a dye such as Acilan Blau usingan electrochemical method. In the process a bipolar packed bed electrochemical reactor consisting of soluble electrodes was used and operated in the batch mode. ...
