Abstract:
Biogas is a clean and environmental friendly fuel that is generated typically from anaerobic degradation of biomass. Biogas, consisting mainly of CO2 and CH4, is an attractive renewable carbon source and its exploitation would be advantageous from both a financial and an environmental point of view. For syngas production the CO2 reforming of CH4 or Dry reforming of methane (DRM) reaction has been proposed as the most promising one. DRM has attracted considerable scientific interest in the past years, as it offers the possibility of simultaneous removal of two inexpensive and abundant carbon containing sources, which are also greenhouse gasses, and their transformation into useful chemical products. Moreover, the utilization of CO2 as a feedstock for producing chemicals is tempting not only because it can contribute to the mitigation of greenhouse gas emissions, but also because it is an interesting challenge in exploring new concepts and new opportunities for catalysis and the chemical industry. In view of the production of useful chemicals and synthetic fuels, the dry reforming reaction of biogas catalyzed by nickel on alumina catalysts seems an appropriate way to produce syngas which is suitable for methanol or Fischer–Tropsch synthesis reactions which require H2/CO ratio of 1 to 2.
