Apparatus and Process for Energy Self-sustainable and High-yield Conversion of Acid Gases (H2S and CO2) into Syngas

H2S and CO2 are two well-known emissions with cumbersome management not yet established bulk utilization plans. The invention converts in syngas and, as the only by-products, elemental sulphur water by means of a dedicated (i) Regenerative Thermal Reactor (RTR) (ii) Acid Gas to (AG2S) process layout thanks overall reaction: 2 + = H2 CO S2 H2O. reaction is globally endothermic, but it can energetically supplied situ minor injection oxygen/air. oxygen generates exothermic S O2 SO2 an appropriate amount so achieve preserve optimal conversion temperature. generated for energy sustainability therefore converted within layout. once-through 75%v 50%v CO2. unreacted reactants split from by-products recycled upstream complete conversion. first utilizing no sources, neither bio nor fossil, generate hence, hydrogen. Two moles obtained every three emissions, also achieving total neutralization relevant cut Technology development has reached out industrialization level. laboratory testing been developed Politecnico di Milano, at facilities Center Sustainable Process Engineering Research (SuPER); bench-scale tests have exerted Sotacarbo Energy SpA industrial application just started Itelyum Regeneration srl, ecorefinery exhausted oil recovery.
