Abstract
There is disclosed pitch prepared from petroleum pitch, which is normally considered to be inferior to coal tar pitch, which petroleum pitch has properties to equal that of coal tar pitch. That is to say, that the softening points, the Conradson carbon, the toluene insolubles and the quinoline insolubles can be matched with those obtained from coal tar pitch. In addition the properties of the petroleum pitch can be varied to meet end user specifications.
