The invention relates to the field of forming of Chabazite molecular sieves, in particular to a method for mold pressing and forming of a Chabazite molecular sieve. The inventor uses water as a structure support agent in the mold pressing and forming process. The method is characterized in that the damage to the Chabazite molecular sieve by pressure is reduced by compression, the adsorption property of the Chabazite molecular sieve is maintained, and the problem of degrading of adsorption property of methane, carbon dioxide and the like after mold pressing and forming of Chabazite is solved. The method for mold pressing and forming of the Chabazite molecular sieve has the advantages that the technology is simple, the cost is low, the effect is excellent, and the method can be applied to large-scale production.
