Abstract

One potential process to incorporate coal or coal-derived materials into existing refinery operations is the addition of coal to delayed cokers, which we refer to as "co-coking". A zero ash yield decant oil blended in a 4:1 ratio with a relatively low ash yield bituminous coal and fed into a laboratory delayed coker, results in a new carbon product that has yet to be thoroughly characterized. Different sections of the coke artifact were cut at progressively further distances from the feed inlet and characterized by various techniques. Ash yields and petrography show that the top and bottom sections are similar, whereas they are clearly different in the middle two sections. Real densities and the concentration of certain major elements (Si and Fe) of the calcined cokes were outside of the range suitable for anode or electrode grade coke. To solve these problems better raw materials will be selected for future experiments (i.e., a low ash yield coal).
