Title: Production of concentrated mesophase pitch
Inventor: YAMADA YOSHIO
IPC: C10C3/10
Filed: 1984-07-18
Abstract: PURPOSE:To obtain continuously the titled pitch which is homogeneous, has evenness in particle size and is highly concentrated, by using a cylindrical reactor in which the inner diameter of a precipitation part is smaller then that of a heat treatment part, and conducting a reaction while keeping the temp. of the precipitation part and the heat treatment part at specified temp. CONSTITUTION:A cylindrical reactor in which the aperture ratio of a heat treatment part 2 to a precipitation part 4 is 1.5-3/1, an inclination part is inclined at an angle of 5-15 deg. to the axis of a tower and the volume of the heat treatment part including the inclination part 3 is 2-4 times that of the precipitation part 4, is used. A raw pertoleum or coal pitch is placed in said reactor. While introducing N2 gas through a gas introducing pipe 7, the temp. of the heat treatment part 2 is kept at 350-470 deg.C and the temp. of the precipitation part 4 is kept at 200-350 deg.C by a temperature controlling part 6, e.g., by means of a mantle heater or an electric furnace to thereby allow a reaction to processed and to grow the formed mesophate sphere into a given size. After the mesophase spheres are precipitated and agglomerated in the precipitation part 4, heating is stopped and the concentrated mesophase pitch phase is taken out. If necessary, concentration and separation are carried out by using a matrix pitch soluble and mesophase pitch-difficulty soluble pitch.
