Preparation and characterization of pyrolytic chars from different biomass samples
(Elsevier Science BV, 2012)
In the present work four different biomass samples (pine cone, soybean cake, corn stalk and peanut shell) were pyrolyzed to 550 degrees C in an inert gas atmosphere and a comparison between the properties of chars produced ...
Humulus lupulus As a Raw Material for Bio-oil Production via Slow Pyrolysis
(Gazi University, 2017)
Humulus lupulus, a kind of hop plant agricultural waste was pyrolysed in a fixed bed reactor with a heating rate of 10 degrees C min(-1) in the presence of N-2 atmosphere. The effect of pyrolysis temperature was investigated ...
Impregnation of 12-tungstophosphoric acid on tonsil: An effective catalyst for esterification of formic acid with n-butyl alcohol and kinetic modeling
(Elsevier Science BV, 2014)
Esterification of formic acid with n-butanol was catalyzed by dodecatungstophosphoric acid, H-3 PW12O40 (DTP) impregnated on tonsil earth. A series of catalysts containing 10%, 20% and 30% of DTP on tonsil earth were ...
Pyrolysis Kinetics and Thermal Decomposition Behavior of Polycarbonate - a Tga-Ftir Study
(Vinca Inst Nuclear Sci, 2014)
This study covers the thermal degradation of polycarbonate by means of Thermogravimetric Analyzer coupled with Fourier transform infrared spectrometer (TGA-FTIR). Thermogravimetric analysis of polycarbonate was carried out ...
Kinetics of the Hydration of Ethylene Oxide in the Presence of Heterogeneous Catalyst
(American Chemical Society, 2009)
Kinetic data on the hydration of ethylene oxide was obtained from both uncatalyzed and heterogeneously catalyzed reactions using a pressurized batch reactor. Amberjet 4200/HCO(3)(-) was used as the heterogeneous catalyst, ...
Kinetic Study of the Hydration of Propylene Oxide in the Presence of Heterogeneous Catalyst
(Assoc Chemical Eng, 2017)
The kinetics of the hydration of propylene oxide was studied using a pres-surized batch reactor for both uncatalyzed and heterogeneously catalyzed reactions. Lewatit MonoPlus M500/HCO3- was used as heterogeneous cat-alyst, ...
Reaction kinetics of the catalytic esterification of acrylic acid with propylene glycol
(Elsevier Science BV, 2009)
The kinetics of esterification of acrylic acid with propylene glycol has been studied in the presence of Amberlyst-15 as a heterogeneous catalyst. The reaction was realized in a batch reactor at different temperatures and ...
Thermal decomposition behavior of tobacco stem Part I: TGA-FTIR-MS analysis
(Taylor & Francis Inc, 2016)
In the present study, the thermal degradation behavior of tobacco stem was examined by means of a thermogravimetric analyzer (TGA) under nitrogen atmosphere at temperature range of 25-1,000 degrees C. The TG curve indicated ...
Sonochemical synthesis and loading of PbS nanoparticles into mesoporous silica
(Elsevier Science BV, 2018)
A sonochemical method was used for simultaneous synthesis and loading of lead sulfide (PbS) nanoparticles into mesoporous SBA-15 (Santa Barbara Amorphous). In this study, the effect of different loading ratios (30, 45, 60, ...
Investigation of the Dissolution Kinetics of Meta-Kaolin in H2SO4 Solution
