The coke microcrystalline texture was studied by a high resolution transmission electron microscopy combined with digital image analytical technique (HRTEM-DI). The length, inclination angle and curvature characterization parameters of coke microcrystalline texture may be used to express the size of coke microcrystal, the order degree of microcrystalline lamellar and the order degree of microcrystalline stacking. The developed crystallographic index which is used to characterize the size and order degree could better reflect the effect of coke crystallinity on the coke reactivity.
