Abstract
Scanning electron microscope, X-ray energy dispersive spectroscopy and thermal gravimetric analyzer were used to detect the surface structure, chemical component and combustion characteristics of petroleum coke particulate matter (PM) samples and PM samples from the exhausts of engine fueled with petroleum coke slurry (PCS) and No. 0 diesel fuel respectively. The results show that PM samples from PCS array sparsely, but PM samples from diesel array closely, cohering mutually. The diameter of PM from PCS is somewhat bigger than that of petroleum coke PM, but in some sort smaller than that of PM from diesel. The superficial major element contents of PM from PCS, such as C, O and S element, are close to those of PM from diesel. But the C and S element contents of PM from PCS are lower than those of petroleum coke, and O element content is higher than that of petroleum coke. The volatile component concentration of PM from PCS is higher than that of petroleum coke, but lower than that of PM from diesel. The fixed carbon content of PM from PCS is lower than that of petroleum coke, but higher than that of PM from diesel. The ignition temperature and burnout temperature of fixed carbon content of PM from PCS and diesel are similar, but both are higher than those of petroleum coke.
