ZHQ‑03 Adsorbent (Modified Activated Clay)

ZHQ‑03 Adsorbent (Modified Activated Clay)

Produced by Qingdao Zhonghaiquan Environmental Protection New Materials Co., Ltd., ZHQ‑03 Adsorbent (Modified Activated Clay) features zero equipment corrosion and purely physical adsorption.

The product has been widely applied at dozens of enterprises including Qilu Petrochemical, Tianjin Petrochemical, Shijiazhuang Petrochemical, Qingdao Refinery, Dalian Fujia, Dongming Petrochemical, Shandong Tianhong, Sinochem Hongrun and Fujian Tenglong, winning consistent favorable comments from all customers.

I. Features and Functions of ZHQ-03 Adsorbent

Prepared with activated clay as the main raw material, ZHQ-03 Adsorbent adopts silicon-aluminum oxides during the production process to adjust its surface acidity. It can catalyze olefins to condense into macromolecular olefin compounds and adsorb the compounds in its pore channels.

This product possesses the advantages of large specific surface area, fast adsorption speed, high adsorption capacity and zero corrosion to equipment. Its adsorption capacity is 4-6 times that of ordinary activated clay. It is widely applicable for aromatics refining in aromatic hydrocarbon units and reforming units, as well as the adsorption refining of lubricating oil in refinery units and anthraquinone degradation products in hydrogen peroxide production enterprises.

(1) Amorphous Silica-Alumina: It has a large specific surface area and relatively abundant medium-strong acid sites. It is adopted to catalyze the condensation of olefins into macromolecular substances and adsorb these substances in its pore channels.

(2) Activated Clay: It features a large pore volume and weak acidity, which can adsorb olefins and condensed products and stably store them in internal pores.

(3) The biggest difference between the new ZHQ-03 adsorbent and products from other manufacturers lies in its pure physical adsorption property. It effectively solves the unsolvable drawbacks of conventional products, including strong equipment corrosiveness, high heavy metal content and serious environmental pollution.

(4) Other domestic manufacturers of modified activated clay still adopt the first-generation production process phased out by our company, which adds zinc chloride during production. This process has a fatal shortcoming of causing severe equipment corrosion, a common problem widely found by end users.
