Abstract: A two-step process for producing microspherical pitch or green coke particles having an average diameter of 30-200 .mu.m from finely divided petroleum or coal pitch having a softening point of 60.degree.-220.degree. C. and a fixed carbon content of 40-75 wt %. In the first step the material pitch is fluidized in the stream of a gas substantially inert to the pitch at a temperature of 100.degree.-800.degree. C., the mixed stream is rapidly cooled to 30.degree.-400.degree. C., and microspherical pitch particles are recovered with or without separate recovery of an oily product. In the second step the pitch spheres are further subjected to thermal cracking and polycondensation by use of a fluidized bed at a temperature of 350.degree.-520.degree. C. for a retention time of 1 min. to 3 hours, and microspherical green coke particles and a light cracked oil are recovered. In both steps a pressure between the ordinary level and 10 kg/cm.sup.2 is used.

Abstract: The invention provides a method for the preparation of a pitch spinnable into pitch filaments as a precursor of carbon fibers starting from a pitch material such as coal tar and coal tar pitch. Different from the conventional procedure involving hydrogenation of the starting pitch, the starting pitch in the inventive method is first heated together with an aromatic oil, preferably, in the presence of a cracking catalyst such as silica-alumina and zeolite at 350.degree. to 500.degree. C. for 10 to 60 minutes under no pressurization with hydrogen and, after removal of insoluble materials, then heated at a temperature of 430.degree. to 600.degree. C. The thus obtained pitch for spinning has good spinnability and the carbon fibers prepared from the pitch have a unique microscopic structure and excellent physical properties exceeding by far the conventional pitch-based carbon fibers and approximating the HP-grade carbon fibers prepared from polyacrylonitrile fibers.
