Method for preparing synthesis gas through carbonate hydrogenation in molten salt system
The invention discloses a method for preparing synthesis gas by hydrogenating carbonate under a molten salt system, which comprises the following steps: mixing soluble salt with carbonate ore powder to obtain a mixture, heating the mixture to enable the soluble salt to be in a molten state, and carrying out hydrogenation reaction under the condition of introducing hydrogen to prepare the synthesis gas. According to the method, the synthesis gas is prepared by hydrogenating the carbonate in the molten salt environment, the reaction process can be accelerated under the condition of no catalyst, and the reaction efficiency between the carbonate and hydrogen is effectively improved by the impregnation effect of the molten salt, so that the conversion rate of the carbonate is remarkably improved, and the improvement of the reaction activity is further promoted; ionic conductivity and active sites of the molten salt are combined with a stable temperature environment maintained by high specific heat capacity of the molten salt, and ideal conditions are provided for effective reaction of carbonate powder and hydrogen.
