Newman, B A

This patent describes improvement in a premium coking process in which an aromatic mineral oil is subjected to delayed coking conditions in a coking drum to convert the mineral oil to premium coke and to volatile coking by-products having a predetermined nominal velocity in the coking drum. The improvement comprises reducing the coarse grain CTE of the premium coke by increasing the nominal velocity of the volatile coking by-products in the coking drum above the predetermined nominal velocity.
