Zinc Oxide Desulfurizer for LPG and Liquid Hydrocarbon Purification
HONREL supplies zinc oxide desulfurizer for LPG and liquid hydrocarbon purification, including replacement products for existing fixed beds. We match the grade to the sulfur composition, liquid-phase conditions, required outlet specification and current bed data.
Send HONREL the feed name and confirm whether it remains liquid through the vessel. Add the sulfur analysis, inlet and outlet limits, operating temperature, current product data sheet and required quantity. We will compare the duty with the available HONREL zinc oxide desulfurizer grades and quote the corresponding product and supply quantity.

The sulfur species decides whether the product fits
For H2S removal, zinc oxide reacts to form zinc sulfide and water:
ZnO + H2S → ZnS + H2O
BASF documents the same irreversible reaction(source: https://download.basf.com/p1/8a8082048fa5910c018fc44d6cb06434/en/Zn_9201_Datasheet_Technical_Data_Sheet_English.pdf) for zinc oxide sulfur adsorbents used with hydrocarbon feedstocks. This reaction gives ZnO its role as a fine purification material for H2S removal.
Liquid hydrocarbon feeds may contain H2S together with COS, CS2 and other sulfur compounds. HONREL uses active ZnO with functional components to combine H2S adsorption with the conversion and absorption of organic sulfur such as COS and CS2. This makes the product series suitable for fine desulfurization in LPG and other liquid hydrocarbon purification duties.
For a mixed sulfur feed, provide the compound breakdown where laboratory data are available. HONREL uses this information to select the appropriate grade, confirm the applicable specification and prepare the required quantity. Total sulfur remains useful, while the sulfur profile makes product matching more precise.
Which HONREL grade should an LPG buyer compare?
HONREL supplies three extruded zinc oxide desulfurizer grades. HY310-C covers low and normal temperature purification, while T305 and HY306-G serve higher temperature duties. The published specifications give procurement teams a direct basis for comparing the required grade.
| HONREL grade | Published temperature range | ZnO or active components | Breakthrough sulfur capacity | Extrudate size | Lateral compressive strength |
|---|---|---|---|---|---|
| HY310-C | 0 to 150°C | ≥90% | ≥10 wt% at 30°C | φ3 to 5 × 5 to 10 mm | ≥60 N/cm |
| T305 | 150 to 400°C | ZnO ≥95% | ≥20 wt% | φ3 to 5 × 5 to 15 mm | ≥40 N/cm |
| HY306-G | 150 to 450°C | ≥95% | ≥20 wt% at 220°C; ≥30 wt% at 350°C | φ3 to 5 × 5 to 15 mm | ≥60 N/cm |
HY310-C is the principal grade to compare for a low or normal temperature purification duty because its published range starts at 0°C. T305 and HY306-G target higher-temperature service. HONREL completes the selection by matching the feed phase, sulfur compounds and required outlet specification with the grade data.
Plants replacing an existing product can also use the HONREL zinc oxide grade replacement guide to compare the current TDS with HY310-C, T305 or HY306-G.
What to send when replacing an existing adsorbent
The fastest route to a credible replacement offer is the current TDS or COA. It shows the chemistry and particle form. It also records the density, strength and declared sulfur capacity that the existing vessel was loaded to accept.
Add the current loading quantity or available bed volume. HONREL publishes a density of approximately 1.0 kg/L for its three grades, with grade-specific tolerances. This lets the supplier compare the likely loading mass without asking the buyer to redesign the vessel.
The feed analysis should identify H2S, COS, CS2, mercaptans and total sulfur where those results are available. Include water and oxygen, plus any contaminant known to foul the current bed.
For liquid service, identify the hydrocarbon and operating temperature. Provide the pressure and confirm whether the product remains fully liquid through the adsorbent vessel.
Finally, provide the required outlet sulfur limit and how the plant measures it. A total-sulfur limit, an H2S limit and a copper strip requirement describe different acceptance tasks. They should not be merged into a single vague request for “deep desulfurization.”
HONREL uses this information to recommend the grade, calculate the corresponding supply quantity and prepare the technical documents required for purchasing approval.
A useful COA must support receiving inspection
A procurement specification should request more than ZnO content. For a fixed bed, the batch documentation should identify the supplied grade, appearance, particle-size range, density, mechanical strength, abrasion rate and the applicable chemical or sulfur-capacity specification.
We publishes lateral compressive strength of at least 60 N/cm for HY310-C and HY306-G. The T305 figure is at least 40 N/cm. Published abrasion limits are no more than 5.0% for HY310-C and HY306-G, compared with no more than 6.0% for T305. These values give buyers clear items to place on the purchase specification and check against the batch COA.
The test basis should accompany the sulfur-capacity figure. Our identifies the applicable temperature beside its published capacity values, giving the buyer a consistent basis for product comparison and purchasing approval.
Where zinc oxide fits in LPG purification
A published study in the Journal of Energy Chemistry evaluated ZnO with commercial LPG and found that it could remove sulfur compounds at different feed concentrations. In industrial purchasing, the feed analysis converts this application into a defined product specification.
HONREL matches the sulfur profile with the active composition, temperature range and sulfur-capacity specification of the available grade. Particle size and mechanical strength are then aligned with the fixed bed and the current material. This gives an LPG producer or hydrocarbon processor one documented basis for technical review, purchasing and incoming inspection.
For other process streams, see HONREL’s overview of zinc oxide desulfurizer applications and its separate guide to natural gas desulfurization with zinc oxide.
Request a specification match and supply quotation
For a replacement order, send HONREL the current TDS or COA, loaded quantity, feed phase, sulfur analysis, temperature range, required outlet limit and destination port. For a new LPG or liquid hydrocarbon purification project, send the same process summary together with the planned bed volume or required trial quantity.
HONREL will compare the request with HY310-C, T305 and HY306-G and confirm whether one of these grades is an appropriate starting point. The quotation can then follow the actual specification and quantity instead of a generic zinc oxide listing.
