摘      要：Dimethyl carbonate(DMC)is an environmentally oxygenated compound which can be used efficiently for soot *** paper compared the soot reduction,soot nanostructure and oxidation reactivity from inverse diffusion flames(IDFs)of the hydrocarbon fuels,namely n-heptane and isooctane doped with *** of DMC additions on soot reduction were *** addition is more effective for the soot reduction of n-heptane/DMC IDF than isooctane/DMC *** morphology and nanostructures of soot particles were investigated by Transmission Electron Microscopy(TEM)and High Resolution TEM(HRTEM),and the soot graphitization and oxidation reactivity were analyzed by X-ray Diflfraction(XRD)and Thermogravimetric Analyzer(TGA),*** results of HRTEM images showed that many larger aggregates were observed for the structures of soot particles from IDFs with DMC *** soot particles exhibited more liquid-like material,more amorphous,higher disorganized layers,and less graphitic than that of IDFs without DMC *** increasing of DMC blending rate,soot particles changed younger to have shorter fringe length,higher tortuosity,and greater fringe *** on the XRD and TGA results,the degree of the soot graphitization level decreased;the soot mass lost significantly faster,and the soot become more reactive.
