The invention relates to a method for anti-adhesion nitrogen increase in the process of producing vanadium nitride, and belongs to the technical field of vanadium nitride alloy production. The technical scheme comprises the following steps of: pretreating raw pellets before the vanadium nitride raw pellets enters a furnace to be fired, and putting the raw pellets into graphite powder, wherein a pretreatment method of sticking and coating the graphite powder on the surface is adopted, and the graphite powder is taken as an anti-adhesion material; and putting the raw pallets uniformly stuck with the graphite powder into a reaction furnace for firing. By the method, the problem of adhesion among products in the process of producing vanadium nitride can be effectively solved, the appearance quality of the products and the finished product ratio are improved, the surface area of nitriding reaction can be increased by 1/8 to 1/2 when the vanadium nitride pellets are fired, and the graphite powder on the surfaces of the pellets can consume partial residual oxygen and protect vanadium carbide/vanadium nitride in the pellets so as to prevent the vanadium carbide/vanadium nitride from being oxidized, improve the nitrogen content in the products and improve the grade and yield of the products. The method is suitable for all vanadium nitride production modes, particularly production of vanadium nitride by the most mature horizontal pusher kiln method at present.
