Abstract

CO2 + C = 2CO; 2CO +2H2O = 2 H2 + 2CO2; CO2 + C+ 2H2O = 2 H2  + 2CO2;

C + 2H2O = 2 H2 + CO2  - 179 Kj / 393 = 0.455 C.

C + 2H20 = 0.5 * CH4 + H20 + 0.5 * CO2;

C + H20 = 0.5 CH4 + 0.5 * CO2 – 52 Kj /393 = 0.13 C.

If domestic cost in Central Europa is USD 100.0/MT of C and CO2 is USD 20.0 /MT of CO2, so

H2 = (1.455 *12 * 100  - 1.455 * 44 * 20) /4 = 116 = 11 cent /kg H2

CH4 = (1.13 * 12 * 100 – 0.63 *44 * 20) / 8 = 100 = USD 70.0 /1000m3 CH4
