Process for producing electrode binder asphalt
Abstract
Abstract ONE HOUR TO PRODUCE AN ASPHALTIC COMPOSITON OF INCREASED SPECIFIC GRAVITY AND SUITABLE FOR THE AFOREMENTIONED USE AS CARBON ELECTRODE BINDERS. ASPHALTIC COMPOSITIONS SUITABLE FOR USE AS BINDERS FR CARBON ELECTRODES CAN BE PREPARED BY A CONTINUOUS PROCESS OF POLYMERIZATION FROM A FEED STOCK COMPRISING A HIGH BOILING OIL PORTION OF THE PRODUCT OBTAINED FROM CATALYTIC CRACKING OF PETROLEUM GAS OILS, PROVIDED THAT PORTION (CYCLE STOCK) IS FURTHER CRACKED IN THE ABSENCE OF CATALYST AND FRACTIONATED TO REMOVE LIGHT ENDS. A SUITABLE POLYMERIZATION IS CONDUCTED IN THE PRESENCE OF AIR AT A RATE FROM ABOUT 6 TO ABOUT 30 STANDARD CUBIC FEET OF AIR PER MINUTE PER BARREL OF LIQUID, AT A TEMPERATURE FROM ABOUT 750*F. TO ABOUT 850*F., AND FOR A PERIOD NOT WEXCEEDING
