A Comparative Characterization of the HPA-MCM-48 Type Catalysts Produced by the Direct Hydrothermal and Room Temperature Synthesis Methods
(Hindawi LTD, 2012)
MCM-48 type support materials synthesized by the direct hydrothermal synthesis (HTS) and room temperature synthesis (RTS) methods were incorporated with tungstophosphoric acid (TPA) in the range of 10-40 wt% by using a wet ...
Bio-oil production via co-pyrolysis of almond shell as biomass and high density polyethylene
(Pergamon-Elsevier Science LTD, 2014)
Biomass from almond shell (aS) was co-pyrolyzed with high density polyethylene (HDPE) polymer to investigate the synergistic effects on the product yields and compositions. The pyrolysis temperature was selected as 500 C, ...
Rapid and catalytic pyrolysis of corn stalks
(Elsevier Science BV, 2009)
Non-catalytic and catalytic rapid pyrolysis of corn stalks was studied in a tubular fixed-bed reactor. The optimum operating conditions giving the highest liquid yield was determined as pyrolysis temperature of 500 degrees ...
Comparative analysis of pyrolysis oils and its subfractions under different atmospheric conditions
(Elsevier Science BV, 2006)
In this paper comparative analysis of bio-oils and their subtraction from static, sweeping gas and steam pyrolysis of apricot pulp, a food industry waste, was investigated. Experimental studies were conducted in a well-swept ...
Kinetics of esterification of acetic acid with 1-octanol in the presence of Amberlyst 36
(Elsevier Science BV, 2012)
Kinetic data on the esterification of acetic acid with 1-octanol were obtained from both uncatalyzed and heterogeneously catalyzed reactions using a stirred batch reactor in toluene. The equilibrium constant, K-C, which ...
A Comparative Study on Characterization of 12-Tungstophosphoric Acid Cesium Salt Depending on Synthesis Methods
(Asian Journal Of Chemistry, 2014)
12-Tungstophosphoric acid cesium salt, Cs2.5H0.5PW12O40, exhibits high catalytic activity for various kinds Of acid-catalyzed reactions. This excellent catalytic effect of Cs2.5H0.5PW12O40 is attributed to its strong acidity ...
Investigation of the effect of low temperature low time alkali pretreatment on hazelnut shells composition and enzymatic hydrolysis
(Gazi University, Fac Engineering Architecture, 2017)
In this study, effect of low temperature-short time alkali pretreatment of hazelnut shells on glucose recovery after enzymatic hydrolysis was investigated. NaOH pretreatment was found to give the highest glucose recovery. ...
Thermo-catalytic co-pyrolysis of recovered heavy oil and municipal plastic wastes
(Elsevier Science BV, 2016)
In this work municipal plastic wastes were co-pyrolyzed together with waste plastic derived heavy oil at 500 degrees C in a stirred batch reactor using beta-zeolite, y-zeolite and m-Ni-Mo-catalysts. The effect of the heavy ...
Ethanol production from hazelnut shells through enzymatic saccharification and fermentation by low-temperature alkali pretreatment
(Elsevier Sci LTD, 2017)
Low-temperature sodium hydroxide (NaOH) pretreatment, enzymatic saccharification and ethanol fermentation were evaluated for hazelnut shell cellulose to fermentable sugars and ethanol. Maximum glucose recovery (48.33 g/100 ...
Paper Based, Expanded Graphite/Polypyrrole Nanocomposite Supercapacitors Free from Binders and Current Collectors
(Electrochemical Soc Inc, 2018)
Expanded graphite (EG) - polypyrrole (PPy) hybrid nanocomposites are used for the fabrication of paper-based highly flexible supercapacitor devices. Brush-painted EG electrodes are utilized as electrodes for the electrodeposition ...
