Supercritical water gasification of waste oils as a source of syngas
2021
A huge amount of waste oil is produced worldwide. Also substantial amount of virgin oils is available that are interesting candidates for upgrading into syngas. Supercritical water gasification (SCWG) can be considered as an aqueous phase reforming process to produce syngas from oils. In this work, a variety of waste and virgin oils were gasified in a continuous down-flow autoclave reactor at supercritical conditions. Experiments were carried out at 430 °C and 660 °C, 25 MPa, with a residence time in the range 103-170 s, in order to investigate gasification and carbon efficiency, hydrogen yield and composition of the produced gas. All the analysed feedstocks were suspended in water at vario…

Supporting Inter-Agency Collaboration in Emergency Management: Recurring Challenges Relevant for CSCW
2023
Emergency management requires effective collaboration between different agencies. This work implies several challenges due to a heterogeneous mix of actors with different procedures, practices, and support tools. Despite being focused in various research streams, emergency responders still report challenges with sharing information and establishing shared situational awareness in responding to complex events. The paper presents results from a large-scale digital tabletop exercise that illustrate recurring challenges related to support for collaborative procedures, a communication network structure combining several media, use of geocollaborative tools, and configuration of collaborative env…
Supercritical hydrothermal synthesis of ZnO nanopowders beyond the critical point : understanding of nucleation and growth steps
2014
The supercritical hydrothermal synthesis of nanopowders (especially metal oxide) has been widely studied. To the best of our knowledge, no nanoparticle formation mechanism has been published yet. In this prospect, this study is dedicated to the understanding of metal oxide nanoparticle nucleation and growth mechanisms. For this purpose, zinc oxide is used as a model material. First, the influence of synthesis operating conditions such as pressure, temperature, pH, precursor concentrations and solution flow rates on particle morphological properties (size, particle size distribution or morphologies) has been investigated. Hence, two approaches have simultaneously been carried out. The first …

La visualisation au service de l'analyse d'interactions Implémentation d'une forme de visualisation générique au sein d'un environnement d'analyse de…
2009
International audience; La visualisation de traces d'interactions est une composante importante de leur analyse dans le cadre de l'évaluation d'usages d'EIAH collaboratifs. Différentes présentations permettent en effet aux chercheurs de plus facilement explorer des corpus parfois très complexes. Dans cet article, nous examinons les besoins de chercheurs désirant visualiser et analyser des traces d'interaction et introduisons la notion de partition d'interaction, une forme générique de visualisation adaptée à ces besoins. Nous montrons de quelle manière cette fonction a été implémentée au sein de Tatiana, un environnement d'analyse de traces. En particulier, nous illustrons comment l'archite…
