description | Provided are activated carbon, a preparation method therefor, and the use thereof in grease, and same belong to the technical field of grease processing. The mass percentage content of silica in the activated carbon is 5.5% to 30%. According to the present invention, by controlling the conductivity, pH, silica content and/or metal ion content of rice husk ash, and after grease is reacted under non-vacuum conditions, the phosphorus content and soap content in the grease can be reduced and the color of the grease can be improved under the premise of satisfying the physical properties of a transesterified grease, and the contents of a 3-MCPD ester and GE in grease can be simultaneously reduced, such that a high-quality, low-pollutant transesterified grease is obtained, wherein the degree of transesterification can be controlled by process parameters. The content of each pollutant in the final product of grease can be effectively controlled while completing transesterification modification, which is suitable for |
