Section 03 · Coal chemistry
Deep conversion
of solid fuel
We turn coal from an energy resource into valuable chemical feedstock: turnkey coal-chemical complexes and the revamping of existing coal-fired plants with chemical conversion cycles.
HSS integrates gasification, hydrogenation, catalytic and deep fractional processing in a single cycle — without the Fischer–Tropsch process.

Coal preparation and gasification
Syngas (CO + H₂) and in-house hydrogen — no separate hydrogen plant required.

Two-stage hydrogenation
Coal hydrogenation on own hydrogen, followed by heavy hydrocarbon processing.

Catalytic cracking and fractionation
Deep fractional processing with intermediate products recycled back into the process.

Marketable chemistry and energy
Gasoline and diesel fractions, BTX, phenol, naphthalene, anthracene oil, hydrogen, sulphur. Residues become heat.

Traditional coal chemistry versus HSS
The industry today runs coking, gasification (Lurgi, Shell SCGP, GE/Texaco, Siemens GSP), direct (DCL) and indirect (ICL) liquefaction — usually as separate plants. HSS integrates their advantages into one complex.
| Criterion | Traditional technologies | HSS technology |
|---|---|---|
| Core technology | Gasification, coking, direct or indirect liquefaction as separate processes | Integrated deep-conversion complex in one cycle |
| Hydrogen supply | Separate plant or external supply | In-house production from coal by gasification |
| Conversion depth | 30–60% depending on technology | Up to 90–95% integrated feedstock use |
| Product range | Limited: coke, syngas, liquid fuel | 10+ products: gasoline, diesel, BTX, phenol, naphthalene, anthracene oil, H₂, sulphur |
| By-products | Partial processing, significant waste | Maximum reuse of intermediate streams |
| Energy efficiency | Average | Higher — internal heat generation and recovery |
| Environmental profile | Considerable waste and emissions | Waste minimised, practically waste-free |
| Investment case | Exposed to the market for one or two products | Reduced market risk through a broad product line |
