Carbonaceous ion exchange materials

Claim 1

A METHOD FOR PRODUCING CARBONACEOUS ION EXCHANGE MATERIALS, COMPRISING: FUSING AND CRUSHING ASPHALTENES, OBTAINED BY THE SOLVENT PRECIPITATION OF OXIDIZED ASPHALT TO OBTAIN GRANULAR ASPHALTENES HAVING A SIZE OF ABOUT 20 TO 80 MESH; ADDING ABOUT 1-10 PARTS OF 20% OLEUM TO EACH PART OF GRANULAR ASPHALTENES WHILE STIRRING AND CRUSHING LARGE PARTICLES; MAINTAINING THE TEMPERATURE AT LEAST EQUAL TO ABOUT 180*F. BUT NOT MORE THAN ABOUT 280* F.; WHEN GELATION AND AN APPARENT DRY POINT IS REACHED, CRUSHING TO A SIZE LESS THAN ABOUT 10 MESH BUT GREATER THAN ABOUT 80 MESH; HEATING THE CRUSHED PARTICLES TO A TEMPERATURE OF ABOUT 280*F.-350*F. WHILE STIRRING; QUENCHING THE HOT PARTICLES IN COLD WATER; REMOVING EXCESS LIQUID FROM THE MIXTURE AND WASHING WITH ADDIDITONAL COLD WATER TO REMOVE UNREACTED STRONG ACIDS; SCREENING SAID PARTICLES THROUGH ABOUT A 12 MESH SCREEN; WASHING THE PARTICLES PASSING THROUGH SAID SCREEN WITH BOILING WATER UNTIL THE EFFLUENT WATER IS COLORLESS; AND DRYING SAID PARTICLES AT A TEMPERATURE OF ABOUT 170*F. TO 190*F. UNTIL SAID PARTICLES HAVE A MOISTURE CONTENT OF ABOUT 20-80%.
