Biogas Steam Reforming in Wastewater Treatment Plants: Opportunities and Challenges

Hydrogen as an energy vector is going to play important role in the global mix. On other hand, wastewater management has become a worldwide concern, urban settlements have been considerably increasing for decades. Consequently, biodigestion produce biogas (rich methane) water treatment plants could be interesting starting point obtain valuable gas that can converted into hydrogen through steam reforming. The aim of this work was review main aspects concerning reforming from plants. For purpose, whole chain, production and purification, considered, paying attention challenges new technologies its optimization. Thus, wide range possibilities offered, direct use syngas high purification (mainly pressure swing adsorption or membrane reactors), presenting advantages disadvantages. In any case, catalysts seems essential, such sulfide coke deposition control should addressed. conclusion, applied reality, with serious implementation at industrial level, according techno-economic assessment.
