All Products
Molecular Sieve

Hengye offers a wide range of molecular sieve products, which are specialized to perform specific separation tasks that allow our users to create a cleaner, higher value end product that meets environmental and industrial requirements. Hengye offers type 3A, 4A, 5A, 13X and specialty zeolites, which have different adsorption capabilities and selectivity and are used in a wide range of industrial processes such as natural gas purificationair separationpetroleum refiningethanol dehydration, and more. Depending on your requirements, our various molecular sieves can adsorb a range of contaminants from compounds such as water, which has a relatively small molecular diameter, to molecularly larger compounds such as heavy mercaptans and sulfides.

Type 3A molecular sieve is used to dehydrate unsaturated hydrocarbon streams and selectively removes water from these streams. This dehydration process allows these hydrocarbon streams to be separated in cryogenic units or transported.

• used to dehydrate unsaturated hydrocarbon streams
• capable of removing water to meet most specifications
• allows hydrocarbon streams to be further processed

Type 4A molecular sieve is used for the dehydration of hydrocarbon streams and can selectively remove contaminants from both liquid phase and vapor phase streams. Type 4A is capable of adsorbing molecules that are smaller than 4 angstroms in diameter, such as water, while allowing larger molecules, such as methane, to pass along to the desired product stream. This purification process allows the hydrocarbon streams to be further separated in cryogenic recovery and is more easily transported.

• used for the dehydration hydrocarbon streams
• capable of removing water to meet most specifications
• allows hydrocarbons to be further processed and transported
• offers an advantageous adsorption capacity

Type 5A molecular sieve is commonly used in air prepurification units to produce oxygen, hydrogen, and other purified gases by removing water, carbon dioxide, nitrogen, and more from he feed stream. The removal of these contaminants is essential for compressed air systems and for purifying gas streams. In gas processing applications, Type 5A is able to adsorb certain mercaptans while still small enough to block larger hydrocarbons from entering the crystal.

• can be used to create high purity gas streams
• capable of removing water, carbon dioxide, and some mercaptans
• allows gas to be further separated, processed or otherwise used
• low cost, while remaining effective compared to 13X molecular sieve

Type 13X molecular sieve is commonly used to deeply dehydrate feed gas prior to cryogenic separation by removing water, carbon dioxide, and hydrocarbons from feed gas. The removal of these contaminants will allow the feed gas to be further separated into the desired product stream. Type X crystals are shaped differently from Type A crystals are tend to offer much larger pore sizes, about 9 Angstroms in diameter. 13X molecular sieve is often used to produce oxygen or in cryogenic distillation processes to deeply dehydrate LNG and LPG streams. There are many variations of Type X crystals with most common being Type 13X.

• used to deeply dehydrate feed gas
• capable of removing water, carbon dioxide, and hydrocarbons
• allows gas to be further separated or otherwise used in compressors
• offers an advantageous adsorption capacity for a wide range of impurities

Specialized molecular sieves are required in a variety of applications in many different sizes and forms. Specialized clays, blending ratios, ion exchanges, and more can be used to create these non-standard grade molecular sieves. Our specialized zeolites have carefully controlled properties that offer superior abilities such as zeolites with high density to allow more capacity per bed and zeolites with proprietary blending processes, which allows deep dehydration or ultrahigh purification abilities. Aside from being designed with specifications that allow improved adsorption or efficiency, zeolites can also be promoted or exchanged with cations to offer very specific functions such as mercury removal, separating nitride and light hydrocarbons from air, or for use in >fluid catalytic crackers.As the manufacturer, Hengye has the capability to produce custom designed products that fit your exact specifications.

Our molecular sieve, or zeolite, is manufactured through a specialized production process that creates reliable, uniform zeolite crystals. These zeolite crystals can be used in powder form or blended with clays to form beads or extrudates. Mixing zeolite with clay produces products that are more durable and easier to handle than powders, which enables molecular sieve technology to be utilized in a wide range of industrial processes. Choosing the right particle size is crucial for your operation and the choice is typically based on the operating pressure requirements, the method of adsorption (PSA vs TSA), production requirements, and overall cost concerns. If given the option in particle size, it’s important to consider the desired Mass Transfer Rate, pressure requirements, and cost control, while minding the requirements for crush strength and adsorption capacity per cycle. The blending of zeolite and clay is performed in a controlled environment with clean equipment to optimize the performance of the zeolite products and ensure that each production batch will meet or exceed industry standards as provided in our Specification Sheets.

Activated Alumina

Activated alumina is a versatile product that is available in a wide variety of grades and forms and used in many applications including bulk dehydration, purifying water, chloride adsorption, sulfur removal, sulfur recovery, and more.

Activated alumina is commonly used in bulk dehydration processes and frequently used as a guard layer to protect more expensive adsorbents and catalysts. As an desiccant, activated alumina is most commonly used to selectively remove water from gases or liquids and can be applied in both PSA and TSA units.

Regenerable activated alumina relies on its physical adsorption properties to adsorb moisture and other contaminants from liquid or vapor streams and can be applied in both PSA and TSA units. Activated alumina can be used to purity various feed streams, such as removing fluorine from drinking water, for purifying hydrocarbon streams, or for drying liquids and gases. Activated alumina offers a high physisorption capacity while maintaining durability and is suitable for cryogenic air purification including use in air dryers and the purification of carbon dioxide, nitrogen, oxygen, and more.

Non-regenerable activated alumina relies on a promoter to offer chemical adsorption capabilities for specialized processes. The promoter reacts with contaminants to create a chemical bond and removes the contaminant from the process stream; this is also the reason why promoted aluminas cannot be regenerated. Promoted activated alumina is more commonly used in liquid phase processes, due to its chemisorption capabilities, which can function at higher temperatures compared to nonpromoted alumina. 

Standard Options
Beads: 1/4 inch, 3/16 inch, 1/16 inch, 7×14 mesh

Non-Standard Options
Beads: 1/2 inch, 14×28 mesh, powder, and more…

Catalysts

Our catalysts are promoted with compounds that increase catalytic function such as titanium dioxide or soda. Catalysts are specialized products that are used to lower the required temperature for a reaction to occur. Typically, a catalyst has a high surface area, which offers a location to assist the occurrence of these desired reactions. Hengye manufactures various types of catalysts from applications such as chloride scavenging for use in reformate stream purification and sulfur removal from natural gas or petroleum streams.

In the Claus process, sulfur is recovered from H2S and can be used for an array of purposes including fertilizer additives. Our SulCat Series offers multiple catalysts for the Claus Process, whether high alumina, promoted or blended, or a Claus Catalysts with high titanium dioxide content to facilitate the conversation of various sulfur compounds into hydrogen sulfide to be suitable for recovery. Hengye offers these product variations to suit the needs of our users, depending on environmental requirements and feed composition. Alumina SulCat can be used for recovery of sulfur from H2S. Promoted SulCat, Blended SulCat, or Super SulCat can be used to recover sulfur from H2S while also converting COS and CS2 into H2S to further remove the content of sulfur from the stream.

Hydro SulCat is a specialized sulfur catalyst for tail gas hydrogenation. For increased sulfur recovery, some units are equipped with a tail gas unit where SO2 is recovered to be recycled back into the sulfur recovery unit to react with H2S and form sulfur.
