Abstract:
     A process for preparing CO2 gas fertilizer features use of quantitative acid-supplying apparatus to supply the strong-acidic solution to the solution of ammonium hydrogen carbonate by controlling the flowing speed of said strong-acidic solution and the reaction of both solutions can release high-purity CO2 gas. After reaction is finished, neutralizing agent is added to neutralize residual acid and to obtain neutral solution N fertilizer that can be directly used as top application.
