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

ABSTRAKT

A catalytic conversion of the natural gas in liquid hydrocarbons is studied and used since many years. Generally, it is done in two steps: conversion of the natural gas in the synthesis gas by catalytic oxidation of methane ("steam reforming") and conversion of the synthesis gas in liquid hydrocarbons by the Fischer-Tropsch process. In this paper, we show that the production of the synthesis gas from methane, in presence of the carbon dioxide or water steam, is possible at atmospheric pressure without catalysts in an electric transferred arc or atmospheric pressure cold discharge like the gliding arc [GLIDARC]. The transferred arc allows obtaining a conversion rate of methane higher than that in the GLIDARC, but with a lower energetic efficiency. The gliding arc reactors have a structure well adapted to the gas injection, notably for the oxidation of CH4 by the water steam at relatively low temperature (350°C) without formation of the soot.
