Provided is a production technology of amino-lignin diesel. An alkali lignin solution is precipitated by an acid to obtain crude lignin. The crude lignin, ammonia and hydrogen peroxide undergo an ammonium reaction. After the reaction liquid is centrifuged, the supernatant is an amino-lignin solution. Then the obtained amino-lignin solution is slowly added to a proportioned mixed liquid which comprises an emulsifier, an auxiliary emulsifier, an oil modifier and diesel with a certain rate. The mixed liquid is uniformly dispersed through a physical means. After dispersion is carried out cyclically for certain times, the mixed liquid is taken for natural precipitation for 1 to 2 days. The supernatant liquid after filtering is the amino-lignin diesel. The amino-lignin diesel of the production technology has the advantages of containing no mental elements, having high content of the lignin, and having less carbon deposition during the long-term engine operation.
