The aggressiveness of the MSG molten salt reaction will decompose any carbon-bearing material into a gaseous stream. The reactions can be operated at pressure by simple pressurization of the input water stream and feedstock. The MSG process occurs at pressure in a single reactor but occurs in three steps: 1) reaction of sodium carbonate with water and carbon generating sodium, carbon dioxide, and hydrogen; 2) instantaneous reaction of sodium with water generating sodium hydroxide and hydrogen; and 3) reaction of sodium hydroxide with carbon and water generating sodium carbonate and hydrogen. Experimental data indicates the feed stock ratios can be adjusted so the net of the reactions can be either slightly exothermic or slightly endothermic. The output can be adjusted by changing the operating conditions to generate hydrogen, synthesis gas, or methane. The net chemical reactions with the system operated for synthesis gas are shown below.
Na2CO3 + 3 C + H2O -- > 2 Na + 4 CO + H2 Equation 1
2 Na + 2 H2O --> H2 + 2 NaOH Equation 2
2 NaOH + C + H2O --> Na2CO3 + 2 H2 Equation 3
The paper will discuss the status of the technology and show data from the laboratory experiments and discuss the status of the pilot plant currently in fabrication.
