From: Synthesis of Methane Hydrate from Ice Powder Accelerated by Doping Ethanol into Methane Gas

Conversion ratio of methane hydrate from ice for reaction time of 24 h at different temperatures. Red triangle, the conversion ratio for the system without ethanol added; and blue square, the conversion ratio for the system with ethanol added. Blue and red dashed lines stand for the average values of the conversion ratio for the system, respectively, with and without ethanol added.
