The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

SINOPSIS

Gasification is a thermochemical path that makes it possible to convert biomass into gases. The main requirements for the transformation process are both a high mass rate transformation and a low content of organic impurities (tars) in the produced gas (syngas).
An allothermal process of gasification, based on the use of thermal plasma to supply the energy for bio-oil conversion is being studied at the CEA (Commissariat à l'Energie Atomique) Cadarache, bio-oil being produced by a pre-processing of biomass by flash pyrolysis. The purpose of this study is to demonstrate the feasibility and cost-effectiveness of the gasification of bio-oil by a thermal plasma process. Indeed, it is expected that the high level of temperature and presence of oxygenated active species in the plasma flow may help to reduce the tar content below 0.1 mg/Nm3, a required value for the Fischer Tropsch post-process and increase the mass yield.
The first step of the work consists in developing a model that takes into account the plasma flow inside the reactor and the liquid material treatment in order to increase the understanding of the process and determine the optimal operating parameters of the plasma reactor.
The bio-oil injected under the form of a liquid jet is subjected to fragmentation, evaporation and chemical reactions in the plasma jet. The modeling work presented in this paper is focused on the break up of the droplets formed by the disintegration of the liquid jet. It uses the Computational Fluid Dynamics (CFD) code Fluent 6.3. Numerical predictions are compared with experimental data obtained with a shadowgraphy system.
