Pyrolysis and Catalytic Upgrading of Lignocellulosic Biomass Using Metal Loaded Zsm-5 Zeolite
(Eta-Florence Renewable Energies, 2016)
The present study is aimed to catalytic upgrading of bio-oil obtained from beech wood sawdust pyrolysis over metal-loaded ZSM-5 zeolites. Ni modified ZSM-5 zeolites synthesized with varying metal loading ratios (1-10 wt. ...
Adsorptive removal of phenol from aqueous solutions on activated carbon prepared from tobacco residues: Equilibrium, kinetics and thermodynamics
(Elsevier Science BV, 2011)
This study consists of producing high surface area activated carbon from tobacco residues by chemical activation and its behavior of phenol removal from aqueous solutions. K(2)CO(3) and KOH were used as chemical activation ...
Bio-oil from olive oil industry wastes: Pyrolysis of olive residue under different conditions
(Elsevier Science BV, 2005)
Olive residues were pyrolysed in a fixed bed reactor under different pyrolysis conditions to determine the role of final temperature, sweeping gas flow rate and steam velocity on the product yields and liquid product ...
Thermal decomposition behavior of tobacco stem Part II: Kinetic analysis
(Taylor & Francis Inc, 2016)
As a continuation of the previous study on the thermal degradation behavior of tobacco stem, this work is focused on the kinetics of pyrolytic decomposition. Thermogravimetric analysis of tobacco stem samples was conducted ...
Upgrading of fast pyrolysis bio-oil over Fe modified ZSM-5 catalyst to enhance the formation of phenolic compounds
(Pergamon-Elsevier Science LTD, 2017)
The present study is aimed to investigate the upgrading of beech sawdust pyrolysis bio-oil through catalytic cracking of its vapors over Fe-modified ZSM-5 zeolite in a fixed bed tubular reactor. The zeolite supported iron ...
