When the ammonia-to-carbon ratio, water-to-carbon ratio and temperature of the total reaction materials are constant, the equilibrium conversion rate will be a certain value. () 2. When the liquid ammonia-to-carbon ratio, water-to-carbon ratio and temperature are constant, the equilibrium conversion rate is a constant value. () 3. The ammonia-to-carbon ratio and water-to-carbon ratio are constant, and the carbon dioxide equilibrium conversion rate will only depend on temperature. () 4. Since the rate of dehydration of methane in the liquid phase is much slower than the rate of methane generation, dehydration of methane becomes the control step of the overall process. () 5. Since the formation of methylammonium is a strongly exothermic reaction, increasing the temperature is always detrimental to the improvement of conversion rate. ()
