Comparison of H2/CO2 ratio in collected gas and temperature reduction in desorber As the H2/CO2 ratio increases, the temperature at the bottom of desorber will decrease. Stoichiometrically, the ideal H2/CO2 ratio is 4 for the methane synthesis process and 3 for the methanol synthesis process (See area within ellipse in the figure). The phase-separation solvent is characterized by a low regeneration temperature, and the H2 stripping regeneration process can further lower the regeneration temperature.
