Phthalocyanine Cobalt Desulfurization Catalyst Price & Bulk Supply
HONREL supplies PDS-HY phthalocyanine cobalt desulfurization catalyst for wet oxidation desulfurization in coke oven gas, semi-water gas, synthesis gas, refinery gas and biogas treatment.
Bulk quotations are based on the required grade, quantity, packing and delivery terms. For continuous desulfurization units, catalyst consumption also matters. A lower purchase price has little value if the system needs a higher make-up rate to hold the required H₂S outlet.

PDS-HY Grades and Specifications
PDS-HY is a blue-grey powder soluble in ammonia water and alkaline solutions. HONREL offers Superior, First-Class and Qualified grades.
| Спецификация | Начальство | First-Class | Квалифицированный |
|---|---|---|---|
| Размер частиц | ≤850 мкм | ≤850 мкм | ≤850 мкм |
| Плотность | ≤0,80 г/см³ | ≤0,80 г/см³ | ≤0,80 г/см³ |
| Insoluble substance | ≤5.0% | ≤8.0% | ≤10.0% |
| Catalytic activity | ≥0.040 min⁻¹ | ≥0.030 min⁻¹ | ≥0.020 min⁻¹ |
| Cobalt content | ≥3.0% | ≥2.70% | ≥2.50% |
| Dichloroporphyrin cobalt sulfonate | ≥70.0% | ≥65.0% | ≥60.0% |
The difference is not just the product label. Higher grades have tighter insoluble-matter limits, higher cobalt content and higher specified catalytic activity.

Wet Desulfurization Performance
PDS-HY is used in circulating wet oxidation systems to support H₂S removal, solution regeneration and sulfur separation.
HONREL specifies H₂S desulfurization efficiency above 99% and an organic sulfur removal rate of 50–80% under the stated process conditions.
For coke oven gas and semi-water gas duties, the listed operating range includes:
| Параметры процесса | Газ коксовой печи | Полуводяной газ |
|---|---|---|
| Catalyst concentration | ≥30 ppm | ≥30 ppm |
| Absorption temperature | 30–35°C | 25–35°C |
| Температура регенерации | 35–40°C | 35–45°C |
| pH | 8–9 | 8–9 |
| Эффективность регенерации | ≥80% | ≥80% |
| Liquid-gas ratio | ≥12 L/m³ | ≥12 L/m³ |
| Suspended sulfur | ≤1.5 g/L | ≤1.5 g/L |
| By-salts | ≤250 g/L | ≤250 g/L |
For ammonia-based desulfurization, volatile ammonia is specified at 6.0–8.0 g/L. For alkali systems, sodium carbonate is specified at 0.4–0.6 mol/L.
Catalyst Consumption Is the Better Cost Indicator
PDS catalyst is used in a circulating solution, so plants normally purchase material for both the initial charge and routine make-up.
This makes actual catalyst consumption more useful than comparing product price per kilogram alone.
The operating result depends on more than dosage. H₂S loading, pH, regeneration air, by-salt concentration and sulfur separation all affect how much fresh catalyst the unit consumes.
When H₂S slip increases, simply adding more PDS is not always the answer. Poor regeneration or sulfur build-up can increase chemical consumption without fixing the root cause.
For an operating plant, the useful KPI is:
Catalyst make-up ÷ H₂S removed
This gives procurement a much better basis for evaluating long-term supply, right?
Regeneration and Sulfur Separation
PDS-HY is designed for regenerative wet oxidation rather than one-pass chemical treatment.
HONREL specifies regeneration efficiency of ≥80% under its listed conditions. Good regeneration helps maintain activity in the circulating solution and control fresh catalyst make-up.
Sulfur handling is equally important.
PDS-HY promotes the formation of larger sulfur particles for easier separation and is intended to reduce suspended sulfur, tower blockage and rising resistance.
In day-to-day operation, the numbers worth watching are:
H₂S outlet, catalyst make-up, suspended sulfur and tower differential pressure.
These directly affect chemical consumption, cleaning frequency and plant availability.
Bulk Supply for Continuous Desulfurization Units
Bulk demand normally comes from three requirements:
Initial charge + routine make-up + plant stock
A new unit needs enough material to establish the required catalyst concentration in the circulating solution.
An operating plant can use its current make-up history to estimate routine demand. This is usually more reliable than ordering against a generic dosage figure.
Plant stock then covers normal consumption and the required delivery cycle.
HONREL can supply PDS-HY for regular industrial purchasing as well as project requirements. Buyers can specify the required quality grade, quantity, packing, destination and delivery schedule.
Промышленное применение
PDS-HY is intended for wet oxidation sulfur removal where H₂S needs to be continuously absorbed, oxidised and separated from a circulating solution.
Typical duties include coke oven gas desulfurization, synthesis gas purification, semi-water gas treatment, refinery gas sweetening and biogas H₂S removal.
The product is suitable for ammonia-based and alkaline desulfurization systems within the specified operating conditions.
For plants with changing feed composition or high sulfur loading, current gas and solution data can be used to confirm the supply requirement.
Bulk PDS-HY Supply from HONREL
HONREL supplies three PDS-HY grades with defined cobalt content, catalytic activity and active-component specifications.
For an existing desulfurization unit, send the current product grade, gas flow, inlet H₂S, catalyst concentration, make-up rate and required quantity. HONREL can use the operating data to confirm the requested product and prepare a bulk quotation.

Часто задаваемые вопросы
What grades of phthalocyanine cobalt desulfurization catalyst does HONREL supply?
HONREL supplies Superior, First-Class and Qualified PDS-HY grades. They differ mainly in cobalt content, active-component content, insoluble matter and specified catalytic activity.
What is the recommended PDS-HY concentration?
A catalyst concentration of ≥30 ppm for the listed coke oven gas and semi-water gas operating conditions.
What H₂S removal performance does PDS-HY provide?
HONREL specifies more than 99% H₂S desulfurization efficiency under the stated process conditions. Actual plant performance depends on feed composition and operating conditions.
Is PDS-HY suitable for coke oven gas desulfurization?
Yes. Coke oven gas is one of the specified industrial uses, with defined catalyst concentration, temperature, pH, regeneration and liquid-gas ratio conditions.
How much PDS-HY is needed for bulk supply?
For an existing unit, current catalyst make-up is the most useful starting point. For a new system, the circulating solution volume and required catalyst concentration are needed to determine the initial charge.
How can I request a bulk quotation?
Send HONREL the required PDS-HY grade, quantity, destination and delivery requirement. For an operating unit, including current H₂S load and catalyst consumption helps confirm the supply requirement.
