Selected papers from the latest issue:Lasers Used in Analytical Micropyrolysis

Publication year: 2011

Laser micropyrolysis gas chromatography mass spectrometry (GCMS) allows analytical pyrolysis to be conducted with micro-spatial resolution. Despite the large range of contemporary laser sources, most previous laser pyrolysis studies have been conducted with continuous wave (CW) infrared irradiation. Here, the laser micropyrolysis analysis of a Sydney torbanite was conducted with three different laser sources–1. CW 532nm; 2. Q-Switched (QSw) pulsed 1064nm; and 3. Q-Sw pulsed 266nm - to compare the molecular analyses attributes of different laser types (λ: 266–1064nm; CW or QSw). The CW 532nm laser irradiation consistently produced high concentrations of n-hydrocarbons, with lesser amounts of cyclic and aromatic...

Determination of Kinetic Parameters and Analytical Pyrolysis of Tobacco Waste and Sorghum Bagasse

Publication year: 2011
Source: Journal of Analytical and Applied Pyrolysis, In Press, Accepted Manuscript, Available online 4 August 2011
C.R., Cardoso , M.R., Miranda , K.G., Santos , C.H., Ataíde
The thermal decomposition of tobacco waste and sorghum bagasse was investigated by non-isothermal thermogravimetric analyses, applying slow heating rates and well-defined conditions. The purpose of evaluating the decomposition was to estimate the kinetic parameters of the analyzed materials. Activation energies and Arrhenius exponential factors were inferred by different estimation methods: the classical methods of Ozawa and Starink and the independent parallel reactions model. The analytical pyrolysis was performed in a micro-pyrolyzer coupled to a gas chromatographer/mass spectrometer. Values of activation energy obtained with single step reaction models by the Ozawa method were: 103.94kJ/mol for tobacco waste and 120.01kJ/mol for sorghum...
