WebBlue hydrogen is when natural gas is split into hydrogen and CO2 either by Steam Methane Reforming (SMR) or Auto Thermal Reforming (ATR), but the CO2 is captured and then stored. As the greenhouse gasses are captured, this mitigates the … WebJun 1, 2024 · ATR uses O2 and steam with direct firing in a refractory-lined reactor with a catalyst bed. It is more cost-effective than SMR, but it requires a substantial feed gas pre-treatment investment, and the fired heater produces CO2 emissions (FIG. 2).

WebFeb 1, 2024 · The results indicate that when uncertainty is considered, SMR-52% and ATR are economically preferable to NGD and SMR-85%. SMR-52% could outperform ATR-CCS when the natural gas price decreases and ... Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. The reaction takes place in a single chamber where the methane is partially oxidized. The reaction is exothermic due to the oxidation. When the ATR uses carbon dioxide the H2:CO ratio produced is 1:1; when the ATR uses steam the H2:CO ratio produced is 2.5:1 The reactions can be described in the following equations, using CO2: WebAdvanced SMRs offer many advantages , such as relatively small physical footprints, reduced capital investment, ability to be sited in locations not possible for larger … citavi web and desktop bundle
