Co-Mo, Ni-Mo and Fe-Mo hydrodesulfurization systems plus a Cu-Zn-Al methanol-to-hydrogen catalyst, matched to feedstock and downstream guard-bed duty.
Sinotech's hydrogenation platform covers organic-sulfur conversion ahead of zinc-oxide desulfurization, plus catalytic hydrogen generation from methanol. Co-Mo, Ni-Mo and Fe-Mo active systems are matched to feed type — natural gas, oilfield gas, coke oven gas, light oil or methanol — and reviewed alongside downstream guard-bed configuration.
Co-Mo or Co-Ni-Mo hydrodesulfurization catalyst converting organic sulfur ahead of zinc-oxide polishing, reducing treated organic sulfur to below 0.1 ppm.
Ni-Mo hydrogenation catalyst with strong organic-sulfur conversion capability for natural gas, refinery gas, water gas and light-oil feedstocks.
Fe-Mo hydrodesulfurization catalyst available in a plant-sulfided grade and a sulfur-free, non-sulfiding grade for coke oven gas, refinery gas, water gas and light oil.
Copper-zinc-alumina catalyst for hydrogen production by methanol steam reforming, built on a co-precipitation process for large effective copper surface area and stability.
| Area | Technical Control Focus | Industrial Relevance |
|---|---|---|
| Active System Selection | Co-Mo / Ni-Mo / Fe-Mo matching | Matches feedstock sulfur form and conversion target |
| Organic Sulfur Conversion | Outlet organic sulfur level | Determines downstream zinc-oxide guard-bed load |
| Operating Window | Temperature, pressure, LHSV/GHSV, H2/oil ratio | Defines integration with feed-gas and reformer systems |
| Strength & Form | Strip / spherical pellet strength | Supports loading and service life |
Each model in the family, set out by process duty, application and role. Full technical datasheets are available on request.
SHY-410 (Co-Mo) and SHY-410A (Co-Ni-Mo) convert organic sulfur in natural gas, oilfield gas, coke oven gas and light-oil feedstocks ahead of zinc-oxide polishing. Uniform active-component distribution gives high activity, good low-temperature performance and long service life, taking treated organic sulfur down to below 0.1 ppm when run in series with a zinc oxide desulfurizer.
SHY-420 is a Ni-Mo hydrogenation catalyst with special promoters on an alumina support, offering strong organic-sulfur conversion across natural gas, refinery gas, water gas and light-oil duty, with good low-temperature activity and mechanical strength.
SHY-440 and SHY-440Y are Fe-Mo hydrodesulfurization catalysts made by co-impregnation, offered in a grade requiring in-plant sulfiding (SHY-440) and a sulfur-free, non-sulfiding grade (SHY-440Y). Both deliver high activity and good low-temperature performance for organic-sulfur conversion across coke oven gas, refinery gas, water gas and light-oil streams.
SHY-485 is a Cu-Zn-Al catalyst — CuO as the main active component with ZnO/Al2O3 as spacer components — made by a co-precipitation process with proprietary promoters. A large effective copper surface area and well-suited pore structure deliver high activity and stability for hydrogen production via methanol steam reforming.
