Biomass screening for syngas production by flash photopyrolysis

Hubert Girault, Mathieu Soutrenon, Wanderson Oliveira Da Silva

A few seconds flash photopyrolysis is used as efficient screening tool for the investigation of selected biomass in producing syngas, hydrogen and biochar. This innovative approach allowed rapid pyrolysis of the biomass, which was followed by a precise gas ...

Investigation and modeling of odors release from membrane holes on daily overlay in a landfill and its impact on landfill odor control

Sami Rtimi

In the present work, we studied the NH(3)and H2S odor fluxes between the exposed working area and the HDPE covering film holes of the daily overlay in an actual landfill site with a daily operating area of 1600 m(2)in Hangzhou, China. We showed that the od ...

Siloxane compounds in biogas from manure and mixed organic waste: Method development and speciation analysis with GC-ICP-MS

Christian Ludwig, Debora Foppiano, Mohamed Tarik

A novel method for the determination of linear and cyclic siloxane compounds (L2, L3, D3, D4, D5, and D6) in biogas was developed by combining gas chromatography (GC) with inductively coupled plasma mass spectrometry (ICP-MS). Using a continuous liquid que ...
