  • Pitch bonded carbon electrode
    Patent number: 4086156
    Abstract: This invention relates to the production of chemical pitch by stripping under reduced pressure steam cracker tar to obtain a pitch having an initial boiling point of between 350.degree. C and 400.degree. C at atmospheric pressure, heat soaking the pitch at 360.degree. to 420.degree. C in the absence of air or oxygen at sub-atmospheric to 4 atmospheres absolute and stripping under reduced pressure the soaked pitch to obtain a product having a minimum softening point (R and B) of 75.degree. C. This pitch can be mixed with coke to make electrodes especially suitable for aluminium production.
