  • Petroleum Coke:
    • Petroleum coke (aka petcoke) is a byproduct of oil refinery with coker units. There are two types of petcoke. Green petcoke can be used as fuel, and calcined petcoke for the manufacture of dry cells, electrodes, etc. (i.e., anode grade coke).
    • Green Petroleum Coke:
      • Green petroleum coke has either a sponge coke or a shot coke morphology. Because of its high heating value and low ash content, green petcoke is often used as fuel blended with coal in coal-fired boilers in power plants or cement kilns, and sometime even used as the sole fuel. Green petcoke has a relatively high sulfur content. This is not a problem for cement manufacturers because the alkaline conditions in a preheater scrub SO2 out of the exhaust gas. In power plants, SO2 is usually captured from exhaust gas by SO2 scrubber units.
    • Calcined Petroleum Coke:
      • Calcined petroleum coke usually has needle morphology. It is produced by calcining green petcoke with low metal content. It is often used to make anodes used in the aluminum, titanium, and steel industries.
  • Coal:
    • There are several types of coal: sub-bituminous coal, bituminous coal and anthracite. We currently export both thermal and metallurgical (coking) coal, with high energy (>11,000 BTU) and low to medium sulphur content (<3%). Most of them are of bituminous coal.
