China Drying Network News Recently, Datang International Chemical Technology Research Institute Co., Ltd. applied for "a method and device for producing synthetic natural gas" obtained the national invention patent authorization. The patent provides a continuous process for producing methane-rich gas with a methane mole fraction of 94% from the coal gasification product without the use of an expensive recycle compressor, which reduces operating costs and also reduces reactors, waste boilers, and steam. Superheater material requirements. The technology has low requirements on the operating temperature of the catalyst, the catalyst bed is not easy to fly, the carbon evolution can be suppressed, the energy consumption in the methanation process can be significantly reduced, and the process flow is reasonable, operability is strong, and energy is saved.
