Zusammenfassung:	The invention discloses preparation and application of a camellia shell modified activated carbon adsorption decolorizing agent, and relates to the technical field of grease decolorization. The preparation method of the camellia shell modified activated carbon adsorption decolorizing agent comprises the following steps: mixing camellia shell powder with water, and carrying out hydrothermal carbonization to obtain camellia shell hydrothermal carbon; and mixing the hydrothermal carbon with a phosphoric acid solution, activating at a high temperature, and carrying out temperature programming under the protection of inert gas to carry out carbonization activation reaction, thereby obtaining the camellia shell modified activated carbon adsorption decolorizing agent. The invention aims to modify camellia shells into an adsorption decolorizing agent, the adsorption decolorizing agent is applied to decolorization of tea oil obtained from tea seeds, and the defects that an existing decolorizing agent is weak in decolo
