Fuel-Grade Pet Coke (Green)
Green coke by sulphur, HGI & calorific value
Fuel-grade petroleum coke — green coke, uncalcined, straight off the delayed coker — is contracted against a short list of numbers that decide whether it works in your kiln or burner. Sulphur (typically 3–6.5%, occasionally under 3% for premium low-sulphur lots) is the first and it is usually the constraint, because it governs your SO₂ compliance and, in a cement kiln, how much sulphur the clinker chemistry can absorb before you get build-up and preheater blockage. Hardgrove Grindability Index (typically 35–45) determines whether your mill can actually pulverise the coke at rate — a low HGI is hard coke and it will cost you throughput. Net calorific value runs ≥ 8,000 kcal/kg and often 8,200–8,500, which is the whole commercial case: pet coke undercuts thermal coal on delivered cost per gigacalorie. Volatile combustible matter (8–12%) drives ignition behaviour and flame stability, total moisture (≤ 8%, often 6–8% as shipped) is deadweight you pay freight on, and ash is remarkably low at ≤ 0.5%.
You buy fuel-grade rather than calcined coke when you are burning it, full stop — cement precalciners and kilns, circulating fluidised-bed and pulverised-coal power boilers, lime and glass furnaces, and blending with coal to lift the calorific value of a low-rank feed. Calcined coke costs several times more and its entire value is in carbon purity and real density for anode use; feeding it to a kiln would be burning money. The practical selection question inside fuel grade is therefore not fuel-vs-calcined but sulphur band against your emissions permit and HGI against your mill. CBIL brokers fuel-grade green coke from US Gulf, Saudi and Chinese sources, connecting refinery and trader allocations with industrial off-takers against SGS certification of sulphur, NCV, HGI, VCM, ash and moisture. Supply is structured in bulk Handysize and Supramax parcels on FOB and CFR terms around your discharge port and burn schedule — send your sulphur ceiling and mill HGI floor and we will work the allocation to it.

Fuel-Grade Pet Coke (Green) — buyer questions
What sulphur level should I specify for a cement kiln?
It is set by two things: your emissions permit and your clinker chemistry. Most kilns run comfortably on 4–6.5% sulphur coke because the raw meal absorbs SO₂ into the clinker, but the moment your sulphur-to-alkali ratio goes out of balance you get preheater build-up and blockages long before you get a stack problem. If you are already running high-sulphur raw material or short on alkali, a 3–4.5% lot is worth the premium. Tell us your permit ceiling and current kiln sulphur balance rather than just asking for the cheapest tonne.
Why does HGI matter as much as calorific value?
Because you cannot burn what you cannot grind. HGI 35–45 is normal for pet coke and it is materially harder than most thermal coal. If your mill was sized for coal, a low-HGI lot will cut throughput and can bottleneck the whole kiln or boiler. Cheap coke that halves your mill rate is not cheap. Give us your mill's HGI floor and we will filter on it.
How much cheaper is pet coke than thermal coal in practice?
Compare on delivered cost per gigacalorie, not per tonne. Pet coke lands at 8,000–8,500 kcal/kg against 5,500–6,000 for typical thermal coal, so a tonne does substantially more work and you move fewer tonnes of freight for the same heat. The offset is sulphur and lower volatiles, which is why most plants blend rather than fire pet coke neat.
What parcel size do you work?
Bulk vessel — Handysize and Supramax are the standard trade lanes, so 25,000–60,000 MT parcels. Supply is structured on FOB and CFR terms around your discharge port draft and consumption schedule. Smaller trial cargoes are possible where a lane already exists but they price accordingly.
