Abstract
PURPOSE: To obtain a pitch composition with improved miscibility with another compounding material without deteriorating characteristics of modified petroleum pitch, by solidifying and granulating a molten mixt. consisting of petroleum pitch obtd. by the heat treatment of asphalt and petroleum asphalt.
CONSTITUTION: A molten mixt. consisting of 1pt. wt. petroleum pitch of softening temp. 160W220°C obtd. by the heat treatment of asphalt and 1/4W4pts.wt. petroleum asphalt of softening temp. 30W80°C is solidified and granulated. The petroleum pitch obtd. by the heat treatment of the asphalt is one thermally modified by blowing superheated steam at about 600W700°C into a vacuum residue obtd. in a petroleum refining process, one modified by heating to 400W500°C without use of steam, etc. The petroleum asphalt is straight asphalt which is a residue from atmospheric or vacuum distillation of petroleum, a propane-deasphalted asphalt obtd. by deasphalting said residue by propane extraction, etc.
