Abstract

Methane gas (CH4) is the main inducer of the so called greenhousegases effect. Recent scientific researchaims to minimizethe accumulationof this gasin the atmosphereand to developprocessescapable of producingstable materialswith added value. Thermal plasmatechnology isa promising alternativeto these applications, since it allows obtaining H2 and solid carbon from CH4, without the parallel formation of byproducts such as CO2 and NOx. In this work, CH4wasdegraded bythermal plasmain order to producehydrogen(H2) andcarbonblack. Thedegradation efficiencyofCH4,selectivityforH2 production as well as the characterizationof carbon blackwerestudied.The best resultswereobtainedin the CH4 flow rate of 5L min-1the degradation percentage and the selectivity forH2production reached98.8 % and 48.4 %, respectively. Atflow rates of lessthan 5L min-1 the selectivityforH2 productionincreasesand reaches91.9 %. Thecarbonblack has obtained amorphous with hydrophobic characteristics and can be marketed to be used in composite material, and can also be activated chemically and/or physically and used as adsorbent material.
