Method for preparing ink wax

The invention discloses a method for preparing ink wax. The method comprises carrying out hydro-conversion on an F-T synthesis product as a raw material under action of a catalyst, carrying out distillation on the hydrogenation product to obtain a component as a sweating raw material for a distillation range and carrying out emulsification and sweating to obtain a desired product. Based on the ordinary sweating method, airflows pass through a wax layer and carry away a liquid component in the sweating process so that a solid component and the liquid component are forcibly separated, and preferably, the sweating raw material and water or a salt solution are emulsified so that the liquid component can be fast discharged. The method has the advantages of low equipment investment, simple production process, low operation cost, safety, energy saving and no solvent pollution. The product has a narrow melting range and can be used as ink wax. 本发明公开了种油墨用蜡的生产方法。该方法以F-T合成产物为原料，在催化剂作用下进行加氢转化；加氢产物经蒸馏制备适宜馏程的组分作为发汗原料；再经乳化、
