Sulfur, chlorine, oxygen, arsenic and oil removal media spanning ambient- to medium-temperature duty across ammonia, methanol, hydrogen and syngas trains.
Sinotech's purification media portfolio addresses sulfur, chlorine, oxygen, arsenic, oil and trace-contaminant removal across ammonia, methanol, hydrogen and syngas process trains. The family spans ambient- and medium-temperature desulfurizers, dechlorination agents, deoxygenation and dearsenization catalysts, a COS hydrolysis catalyst, an oil absorbent and an activated-carbon adsorbent — each matched to contaminant type, concentration and operating temperature window.
Ultra-purification guard agent removing inorganic and organic sulfur to 0.02 ppm ahead of methanation and other deep-purification duties.
Dechlorination agent pair for ambient-temperature chlorine removal from hydrogen, nitrogen, synthesis gas, reformer tail gas and liquid alkanes.
Nickel-alumina catalyst for ammonia decomposition into hydrogen and nitrogen, also applied to natural-gas intermittent reforming and partial-oxidation syngas duty.
Activated-alumina catalyst that hydrolyzes COS to H2S at low temperature, enabling deep organic-sulfur removal alongside ambient-temperature H2S desulfurizers.
Dry ambient-temperature H2S removal agent reducing sulfur below 1 ppm, tolerant of steam, coal tar and small amounts of carbon black under harsh conditions.
Multi-promoter activated carbon for fine removal of benzene, naphthalene, CS2, mercaptans and other organic sulfur species; regenerable and pairable with SPF-548.
Nano-active zinc-oxide desulfurizer with up to 35% saturated sulfur capacity, in medium-temperature and ambient-temperature grades for fine gas and liquid purification.
Silicate-carrier oil absorbent that protects ammonia synthesis, shift and fine-chemical catalysts from oil carryover, without removing H2S or breaking down under moisture.
Platinum-palladium dehydrogenation catalyst removing hydrogen from CO2 feed gas to below 50 ppm, eliminating hydrogen-oxygen explosion risk in fertilizer plants.
Palladium-alumina deoxygenation catalyst removing trace oxygen via reaction with hydrogen and CO, applied across metallurgy, electronics and chemical purification systems.
Copper-zinc-aluminum oxide purification agent removing arsenic, chlorine and sulfur from olefin feed monomers ahead of polyolefin polymerization.

SPF-505 is an ultra-purification guard agent that takes feed-gas total sulfur from 0.1 ppm down to 0.02 ppm. It removes inorganic and organic sulfur simultaneously, with particular strength against organic sulfur, high sulfur capacity, good stability and a wide operating temperature window — supplied in cylinder and spherical forms.
SPF-512 (gas-phase) and SPF-514 (gas/liquid-phase) remove inorganic chlorine at near-ambient temperature. SPF-512 offers high chlorine capacity and high active-component content; SPF-514's small particle size gives chlorine capacity comparable to liquid-phase dechlorination agents, with better steam resistance. Organic chlorine should be hydrogenation-converted before either agent is used.
SPF-528 is a sintered nickel-alumina/calcium-aluminate catalyst that cracks ammonia into hydrogen (reducing gas) and nitrogen (protective gas), and also supports natural-gas intermittent reforming or light-hydrocarbon partial oxidation for ammonia or methanol synthesis gas. It is rated for long-term operation between 800 and 1200°C with good resistance to mechanical breakage under thermal fluctuation.
SPF-536 hydrolyzes COS to H2S at low temperature (COS + H2O → H2S + CO2), converting carbonyl sulfide into a form that ambient-temperature H2S desulfurizers can remove. Built on a specially treated activated-alumina carrier, it needs no pre-reduction and achieves COS conversion of 90% or higher, with an expected service life of about two years.
SPF-548 is a dry, ambient-temperature iron-oxide desulfurizer that brings H2S down to below 1 ppm across coal gas, coke oven gas, liquefied gas, biogas and CO2 process streams. It holds high activity and sulfur capacity at normal or pressurized operation and tolerates steam, trace carbon black and coal tar under demanding field conditions.
Sinotech's activated carbon adsorbent is treated with multiple promoters for ambient-temperature, normal or pressurized adsorption duty. It removes high-molecular organics such as benzene and naphthalene, plus CS2, mercaptans, thioethers, disulfides, SO2 and other organic sulfur species, and also adsorbs H2S directly. Paired with an ambient-temperature iron oxide desulfurizer (SPF-548), it supports true ambient-temperature fine desulfurization and can be regenerated through multiple cycles.
Cross-reference: this process-gas activated carbon shares duty with Sinotech’s dedicated Activated Carbon & Adsorption Media family — see that page for the full grade range and selection parameters.
SPF-560 (medium-temperature) and SPF-560A (ambient-temperature) are nano-active zinc-oxide desulfurizers reacting H2S to ZnS. Under industrial conditions SPF-560 takes treated gas below 0.1 ppm H2S with saturated sulfur capacity up to 35%, while SPF-560A extends the same chemistry to ambient-temperature service with adjustable ZnO content for different plant requirements.
SPF-572 and SPF-574 are cylindrical, silicate-carrier oil absorbents that protect ammonia synthesis, shift and fine-chemical synthesis catalysts from oil carryover, extending catalyst life and maintaining activity. Developed pore structure gives high oil capacity and mechanical strength without removing H2S, and the pellets resist powdering or sludging at high temperature or under water immersion.
SPF-585 (catalogued under model SPF-585B) is a platinum-palladium dehydrogenation catalyst that removes hydrogen from CO2 feed gas, positioned as a domestic alternative to imported dehydrogenation catalysts. It brings residual hydrogen in tail gas below 50 ppm, removing the hydrogen-oxygen explosion risk in downstream handling.
SPF-592 is a palladium-alumina deoxygenation catalyst that removes oxygen via reaction with hydrogen, carbon monoxide and similar reducing gases. High deoxygenation activity, good stability and long service life support single-pass oxygen removal to below 1 ppm across a broad temperature and pressure range.
SPF-604 is a copper-zinc-aluminum oxide purification agent developed for arsenic removal, dechlorination and desulfurization in olefin feed monomers. It delivers good activity at normal temperature with high arsenic- and sulfur-removal efficiency, protecting downstream polyolefin catalyst from these poisons.
