Surface sediments collected from 33 stations along the Ambarli Harbor, the Sea of Marmara, were analyzed for petroleum aromatic hydrocarbons by UV-fluorescence. Higher concentrations of total aromatic hydrocarbons were found of all the samples collected during May 2009, with levels ranging 1860 and 72 μg/g eq oil (205 and 7 μg/g chrysene eq.). The spectra indicate dominant pyrolytic origins in ...

The problem of plastic waste is very flourished in the current era modern life. In this study, a three-condenser pyrolysis reactor was applied to obtain fuels form oil#1, oil#2, and oil#3 from waste. Gas Chromatography-Mass Spectroscopy (GC-MS) technique carried out analyze fuel for profiling study. Characterization using GC-MS indicated domination hydrocarbon compounds found oil#1. existence o...

This study investigated catalytic microwave pyrolysis of Douglas fir sawdust pellets using carbon catalysts produced from corn stover. The effects of catalyst to biomass ratio on the bio-oil, syngas, and biochar yields were determined. Functional groups (carbonyls, phenolics, lactones, carboxyls) of carbon catalysts and GC/MS analysis were used to study the catalytic pyrolysis of Douglas fir sa...

A reactor was designed and commissioned to study the fast pyrolysis behavior of banagrass as a function of temperature and volatiles residence time. Four temperatures between 400 and 600°C were examined as well as four residence times between ~1.0 and 10 seconds. Pyrolysis product distributions of bio-oil, char and permanent gases were determined at each reaction condition. The elemental compos...

In this study, sewage sludge and mycelial waste from antibiotic production were pyrolyzed in a batch scale fixed-bed reactor as examples of two kinds of typical industrial biomass wastes with high nitrogen content. A series of experiments were conducted on the rapid pyrolysis and the slow pyrolysis of these wastes in the temperature range from 500–800 °C to investigate the Fuel-N transformation...

We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to...

fast pyrolysis is an attractive technology for biomass conversion, from which bio-oil is the preferred product with a great potential for use in industry and transport. corn wastes (cob and stover) and eucalyptus wood are widely being produced throughout the world. in this study, fast pyrolysis of these two materials were examined under the temperature of 500 °c; career gas flow rate of 660 l h...

A pyrolysis study on a species of brown algae Saccharina japonica was carried out in a fixed-bed reactor. The yields of bio-oil and bio-char obtained at 450 C were 47 % and 33 %, respectively. The raw S, japonica, ethanol and acid pretreated samples and the resulting pyrolysis products were also characterized with respect to proximate and ultimate analysis, and higher heating value. The crude b...
