H-Coal

H-CoalTS converts coal directly into liquid fuels. Coal conversion typically reaches 95%. It is the most efficient process with a typical yield of four to five barrels of oil per ton of coal on a moisture-free basis – including coal gasification that supplies hydrogen. The major products are: high naphthenic naphtha, diesel fuel with good cold flow properties and low sulfur fuel oil that can meet specifications after downstream reforming or hydroprocessing.

Technology description

The H-Coal Process, for direct conversion of coal to high quality distillate fuels, uses our commercially proven H-Oil ebullated-bed reactor system. Coal is crushed and pulverized to finely sized particles, and mixed with recycle oil to make a slurry that can easily pass up and out of the reactor with the liquid and gaseous products, while the much larger catalyst particles remain in the ebullated-bed reactor.
Extruded catalyst is periodically replaced in the reactor, without shutdown. It is only weakly prone to metal poisoning and can be regenerated.

The need for improved yield and selectivity have led to the two-stage catalytic coal liquefaction process H‑CoalTS (two stage).The two-stage process enables the optimization of the operating conditions in each reactor.

The H-CoalTS reactor system is superior to other thermal or slurry based catalyst systems currently under evaluation and it uses a fully commercially proven technology.

Shenhua company chose Axens technology for the first DCL unit in the world

Unconverted residue can be utilized either as solid flakes or as additional feed to a gasification unit.

The environmental footprint of the liquefaction unit can be reduced using carbon capture and storage. Up to 80% of the CO2 can be captured.
