Petroleum coke (often abbreviated pet coke or petcoke) is a
carbonaceous solid delivered from oil refinery coker units or other
cracking processes.[1] Coking processes that can be employed for
making petcoke include contact coking, fluid coking, flexicoking
and delayed coking. Other coke has traditionally been delivered
from coal.
This coke can either be fuel grade (high in sulphur and
metals) or anode grade (low in sulphur and metals). The raw coke
directly out of the coker is often referred to as green coke.[1] In
this context, "green" means unprocessed. The further processing of
green coke by calcining in a rotary kiln removes residual volatile
hydrocarbons from the coke. The calcined petroleum coke can be
further processed in an anode baking oven in order to produce anode
coke of the desired shape and physical properties. The anodes are
mainly used in the aluminium and steel industry.
Petcoke is over *0 percent carbon and emits 5 to *0 percent
more carbon dioxide (CO2) than coal on a per-unit-of-energy basis
when it is burned. As petcoke has a higher energy content, petcoke
emits between *0 and *0 percent more CO2 than coal per unit of
weight.[2] The difference between coal and coke in CO2 production
per unit energy produced depends upon the moisture in the coal
(increases the CO2 per unit energy *- Heat of combustion) and
volatile hydrocarbon in coal and coke (decrease the CO2 per unit
energy).
