Abstract The thermal degradation and kinetic analysis for oil palm frond (OPF) trunk (OPT) with its ashes were investigated using thermogravimetric approach (TGA). OPF ash, OPT ash mixtures are used as a natural source of catalysts in the pyrolytic conversion wastes to bioenergy. TGA experiments conducted range heating rates 10-100 K/min from temperature 323 K 1173 K. Coats-Redfern model is app...

*Cheema, N; +*Salkeld, S; **Hawkins, N; **Bailey, K; *Cook, S +*Fellowship of Orthopaedic Researchers, Inc., Metairie, LA [email protected] INTRODUCTION: The purpose of this study was to determine if particulate pyrolytic carbon debris was generated during wear simulation of the Regain™ lumbar nuclear disc replacement articulating on cortical bone. The Regain device is fabricated from pyrolyti...

The combination of delocalized units for the fast pyrolysis biomass to produce bio-oil followed by centralized gasification appears as an economically attractive option full-scale production syngas because transportation is less costly than that biomass. First goal this study lies in validation a feeding device made up line-thermostated at 60–80 °C and non-atomizing injector cooled water. This ...

The nature and composition of the surface of pyrolytic graphite and the consequent possible effects, when the material is used as an electrode. are considered on the basis of the structure of the graphite and of the handling and/or treatment to which the electrodes may have been exposed. Because of the relatively limited studies on pyrolytic graphite, certain aspects of the behavior of other ty...

The immediate catalytic conversions of pyrolytic bio-oils from pine sawdust and soybean shell over mesoporous catalysts (silica, alumina, silica-alumina) their combinations with Y zeolite, were studied. effect mesoporosity acidity on the bio-oil deoxygenation conversion into hydrocarbons was investigated. Pyrolysis performed in an integrated pyrolysis–upgrading reactor, for 7 min under a 30-ml/...

A scalable technique of chemical vapor deposition (CVD) growth of ultra-thin graphitic film is proposed. Ultra-thin graphitic films grown by a one-step CVD process on catalytic copper substrate have higher crystallinity than pyrolytic carbon grown on a non-catalytic surface and appear to be more robust than a graphene monolayer. The obtained graphitic material, not thicker than 8 nm, survives d...

The pyrolytic kinetics of Phragmites australis was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for P. australis with Dollimore method. The values of apparent activation energy, the most probable mechanism f...

The slow pyrolysis characteristics of lignocellulosic biomass and its three major components via a Thermogravimetric Analyzer coupled with Fourier Transform Infrared Spectrometer (TGA-FTIR) was studied. Different compositions ratios cellulose, hemicellulose, lignin, olive pomace, sunflower waste, pinecone were selected. main decomposition temperature ranges xylose (hemicellulose) lignin showed ...
