A b s t r a c t Substantially nonadhesive pitch spheres having an average diameter of 30-200 µm, oil content of 55-15 wt%, fixed carbon content of 45-85 wt% and softening point of not lower than 80°C and capable of maintaining the spherical shape at ordinary temperature and under compression at 1 kg/cm2 are provided. The pitch spheres are produced by atomizing molten pitch in an inert gas stream and rapidly cooling the atomized pitch. The pitch spheres may be converted to green coke spheres by heat- treating the pitch spheres to accelerate polymerization thereof. The spherical pitch and green coke particles are easy to handle, transport, store and use.
