Pyrolysis kinetics of walnut shell and waste polyolefins using thermogravimetric analysis
(Elsevier Sci LTD, 2017)Co-pyrolytic behavior and kinetics of walnut shell (WS), polypropylene (PP), low density polyethylene (LDPE) and their blends were investigated using a thermogravimetric analyzer. WS and plastic samples were blended weight ... -
Preparation of Ni-based catalysts to produce hydrogen from glycerol by steam reforming process
(Pergamon-Elsevier Science LTD, 2016)Nickel and Nickel-Palladium-catalysts supported on Al2O3-ZrO2, Al2O3-ZrO2-La2O3 and on Olivine were synthesized using a combination of sol-gel and wet impregnation methods. The influence of the formulation on their textural ... -
Optimization of Alkaline Pretreatment for Enzymatic Saccharification of Poppy Stalks
(North Carolina State University Dept Wood & Paper Sci, 2014)Response surface methodology (RSM) was employed to optimize dilute alkaline pretreatment conditions for the maximum glucose yield of poppy stalk, with respect to NaOH concentration (1.0 to 3.5%, w/v), pretreatment temperature ... -
Beneficial-Effects of Hydrogen Pressure in the Pyrolysis of Biomass - a Study of Euphorbia-Rigida
(Elsevier Science BV, 1993)Fixed-bed pyrolysis and hydropyrolysis experiments at different temperatures and pressures have been conducted on a sample of Euphorbia Rigida extracted with n-hexane and methanol to remove low molecular mass terpenoids ... -
Effect of Lignite Addition and Steam on the Pyrolysis of Turkish Oil Shales
(Butterworth-Heinemann LTD, 1992)Steam was found to be a more effective sweep gas than nitrogen at low velocities in fixed-bed pyrolysis of Goynuk oil shale but, at higher velocities and in fluidized-bed pyrolysis, the differences were considerably less ... -
Steam pyrolysis of an industrial waste for bio-oil production
(Elsevier Science BV, 2011)Potato skin, a food industry waste, was pyrolysed under three different atmospheres namely static, nitrogen, and steam to produce bio-oil and its derivatives. The oil yield obtained at 550 degrees C was 24.77% in static ... -
The effect of pyrolysis atmosphere on bio-oil yields and structure
(Taylor & Francis Inc, 2017)A food industry waste, almond shell, was pyrolyzed under three different environment static, nitrogen, and steam to produce bio-oil and its derivatives. The oil yield obtained at pyrolysis temperature of 600 degrees C was ... -
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, ... -
