Dalian Haixin Chemical Co., Ltd. products

Y Zeolite is a kind of micropores crystal material with framework structure, and the basic structure element is Si-O and Al-O tetrahedron which can form the secondary structure element like 4 membered ring, 6 membered ring and 8 membered ring by Si-O or Al-O bond. By connected with each other, the secondary structure element can form β cage.8 β cages arrange as diamond crystal pattern, and each C in diamond structure is replaced by β cage, and adjacent β cages are connected as Si-O -Si （Al）with 6 membered rings to form octahedral zeolite cage. A cell unit can be formed by connected octahedral zeolite cages with 12 membered rings.12-membered ring is the main window of octahedral zeolite cage with 0.74 nm of pore diameter.

ZSM-5 from Dalian Haixin Chemical Co., Ltd has high hydrothermal stability, high specific surface area, outstanding shape selective catalytic effect, wide range of silicon to aluminum ratio, unique surface acidity and low carbon deposition. Based on above advantages, our ZSM-5 can be widely used in many fields include oil refining industry, fine chemical industry as well as environment protection industry. In addition, ZSM-5 with different silicon to aluminum ratio can be used in different application fields.

SSZ-13 molecular sieve，with chabazite (CHA) topology, consists of AlO4 and SiO4 tetrahedron connected end to end by oxygen atoms, formed a ellipsoid cage ï¼ˆ0.73 nm×1.2 nm）with eight membered ring structure and three-dimensional cross channel structure. The size of pore is 0.38 nm×0.38 nm and the specific surface area is up to 700 m2/g. SSZ-13 shows excellent performance of NOX removal from automobile exhaust, MTO, and CO2 absorption and separation, owing to ordered pore structure, good hydrothermal stability, and more surface proton acidic center and exchangeable cations.

SAPO-34 from Dalian Haixin Chemical is formed by introducing Si into the Aluminum phosphate framework with PO2+、AlO2+ and SiO2 tetrahedron, electronegativity, surface proton acidic center and exchangeable cations. The silicon aluminum phosphate zeolite with different topological structure and acidity can be prepared by changing the synthesis conditions and the Si content. SAPO-34 is widely used in catalytic conversion of light alkanes to light alkenes, C4~C8 linear alkenes/alkanes cracking to light alkenes, purification of automobile exhaust, catalyst carrier, membrane separation materials and luminous material because of its three-dimensional cross channel, the eight membered ring orifice diameter and medium acid center.

Molecular sieve activated powder is a molecular sieve after original powder dehydration, it has good dispersibility and a fast rate of absorption, it is used in adsorption in special situations in industry: Mixed with the material dispersion adsorption; as amorphous desiccant and so on. As additives or binders aggregate for coatings, paints, resins and certain, to lower moisture, eliminate bubbles, increase uniformity and strength; This product can also be as a desiccant to add to the insulating glass combined rubber.

Pd catalyst is mainly used for deep purification and deoxy for hydrogen, argon, nitrogen and other gases, widely used in a large fertilizer plant, hydrogen plant. The product has high catalytic activity, high-deoxy-depth, easy to operate, safe to use, do not need regeneration, long life characteristics. The product use activ ated alumina or titania as a carrier, which can meet different demand for the customers.

HC-6 deoxidizing agent is used to remove oxygen from propylene for propylene polymerization. It is also used to deeply remove trace oxygen form non-acidic gas. Characteristics:high adsorption capacity, high crush strength.

Carbon Molecular Sieve used in the PSA Nitrogen generation, the Nitrogen generation by Pressure Swing Adsorption (PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristics of the Carbon Molecular Sieves (CMS).

Insulating glass desiccant from Dalian Haixin Chemical is mainly suitable for moisture absorption in the insulating glass to avoid fogging, even at very low temperature to keep clear and transparent and improve the thermal insulation performance of insulating glass, extend the service life of the insulating glass.

The effective pore opening of molecular sieve 3A is 3 Angstrom. It adsorbs only water.By pore optimization, our product is with high adsorption speed,high crush strength,long life time and anti-contaminative.All these advantages have made it come to be the most essential and necessary desiccant for the applications in petroleum and chemical industries.
