VOC Treatments

There are several options of Volatile Organic Compounds (VOC) Treatment, including destructiveness and non-destructive methods. Combustion method, Biological Oxidation, Thermal Oxidation, Photocatalytic Oxidation (PCO), and Low-temperature plasma (LTP) along with its integration technology are classified as destructiveness, while Physisorption, Coagulation method and Membrane separation technique are belong to Non-destructive methods.

Zeolite catalyst adsorbents are used for VOC treatment by physisorption method, which has a long operation life for more than ten years, it can be regenerated repeatedly for 2000 cycles without any performance degradation.

There Are Mainly Two Applications for Zeolite Catalysts Using in VOC Treatments.

For Zeolite Concentration Runner Equipment (ZCRE)

Zeolite Concentration Runner (ZCR) is made by ceramic fiber as its basic material, with our Hydrophobicity zeolite covered onto the surface of ZCRE, as a adsorption material, it can be designed and made to cellular disc shape, which to be regarded as the core part of Zeolite concentration runner technology.

Adsorption in Fixed Bed

Xing materials R & D team broke through technical barriers of low efficiency or insufficient adsorption volume for the zeolite catalysts, which have negative impact on stability and constancy.

Xing Materials Zeolite Catalyst Characteristic

In target demand for the environmental industry, Xing material production engineers prepared two types catalysts for VOC gas treatment, ZMS-5 zeolite catalyst and Y-type zeolite adsorbents, which are selectively adsorbing various VOC gas in customers demands.
Meanwhile Xing materials advantage for zeolite catalyst are specific as HYDROPHOBIC NATURE, High Adsorption Capacity for n-hexane (C6H14), HYDROPHOBIC NATURE, High Adsorption Capacity for n-hexane (C6H14), Hydrothermal Stability (no change of Crystal Structure after 1200℃ roasting), Acid Fastness (remove all kinds of acids except for Hydrofluoric Acid), Shape Selectivity (Adsorbent Pore Character), Long Operation Life (more than 8 years).

Mainstream Application Area for Zeolite Molecular Sieves

Adsorption Products for the Natural Gas Process Industry
Generally, natural gas used to produce chemical raw materials contains saturated water, H2S, organic sulfur (mercaptan), CO2 and other impurities. In order to meet the needs of liquefaction, deep cooling and other processes, the impurities need to be removed as much as possible to achieve the application requirements of the finished gas product.

Drying and Purification
Water will significantly raise the dew point of natural gas, making it freeze in the process of liquefaction, pipeline transportation or deep cooling separation, and then form a hydrocarbon hydrate that can precipitate out and block the equipment and pipelines. This presents potential and significant safety risks. In addition, H2S and CO2 in natural gas can easily react with other substances, resulting in acid and alkaline corrosion of the pipeline equipment.

It is one of the most widely used and mature methods to deep dehydrate and dry natural gas by molecular sieve.
