STUDY ON GC-MS PROFILE OF FUELS PRODUCED FROM PLASTIC WASTE CONVERSION VIA THREE-CONDENSER PYROLYSIS REACTOR

Bacterial mutagenicity of pyrolysis tars produced from chloro-organic fuels.

Droplets of toluene and three chlorinated organics, ortho-dichlorobenzene, 1,2-dichloroethane, and trichloroethylene, were pyrolyzed in pure nitrogen. The composition and bacterial mutagenicity of the product tars were measured. The presence of organic chlorine was found to affect both pyrolysis product tar composition and total tar mutagenicity. Pyrolysis in the absence of chlorine produced ta...

Pyrolysis-GC/MS fingerprinting of environmental samples

This paper describes four recent applications of analytical pyrolysis in environmental science and engineering. In all applications, samples were analyzed in order to provide information about the origin of organic matter or changes to an organic matrix. In the first application, pyrolysis-gas chromatography/mass spectrometry (GC/MS) and pyrolysis-GC/flame ionization detection (FID) were used t...

Study of Analytical On-line Pyrolysis of Oils from Macauba Fruit (Acrocomia sclerocarpa M) via GC/MS

Estudos pirolíticos dos óleos vegetais das partes (endocarpo mais mesocarpo e epicarpo) do fruto da Macauba (Acrocomia sclerocarpa M.) foram realizados sob atmosfera de hélio usando-se um pirolisador de filamento modelo Girdel 75 -Py -1, conectado diretamente a um CG/EM. Os experimentos foram realizados em diferentes temperaturas e tempos de pirólise, para avaliar como estes parâmetros afetam o...

Polymer Analysis Using Pyrolysis-GC-FTIR-MS and GC-AED

Catalyst-assisted Conversion of Pyrolysis Bio-oil into Fuels

The aldol condensation of model compounds furfural and acetone on the selected base catalysts have been performed. The activity of MgO was compared with industrially produced hydrotalcite and the series laboratory prepared hydrotalcites. Si×MAl2O4 hydrotalcites (M = Mg, Zn, Ni, Co, Cu, and Fe) were prepared by the solgel method at low calcination temperature of 300°C. The properties of the cata...
