Abstract: A quantitative evaluation method for activation energy of pyrolysis of graded diesel particulates is disclosed, relating to the technical field of diesel particulate emission. The present disclosure includes four major steps: grading of particulates, pretreatment of the particulates, thermogravimetry test for the particulates in different particle size ranges, and mathematical analysis on obtained thermogravimetric data by using a Flynn-Wall-Ozawa (FWO) formula.
