China Catalyst Holding Co.,Ltd. (688235.SH) is a high-tech enterprise specializing in the research, development, production, and sales of specialty zeolites and novel catalytic materials. It operates within the catalysts and auxiliaries manufacturing subsector of the chemical raw materials and chemical products manufacturing industry, with its core positioning as a provider of high-performance zeolite materials and their application solutions. The Company’s primary business spans four major directions: zeolite catalysts, environmental protection catalytic materials, new-energy catalytic materials, and chemical process solutions. Its product portfolio includes representative zeolites such as ZSM-5, SAPO-34, SSZ-13, Beta, and Y-type, which are widely applied across petroleum refining (catalytic cracking, alkylation, isomerization), coal chemical industry (methanol-to-olefins, MTO), environmental protection denitrification (SCR catalyst supports), new energy (hydrogen purification, CO₂ capture), and fine chemical industries. Leveraging proprietary core technologies—including hydrothermal synthesis of zeolites, precise control of crystal grain size, construction of hierarchical pore structures, and metal modification—the Company has established a full-chain R&D system covering fundamental research, pilot-scale amplification, and industrial mass production. As of the end of 2023, it held 79 authorized invention patents and had led or participated in formulating three industry standards. The Company has obtained ISO 9001, ISO 14001, and ISO 45001 management system certifications, and holds a Safety Production License, a Pollutant Discharge Permit, and hazardous chemicals trading registration qualifications. Its Dalian production base has been designated by the Ministry of Industry and Information Technology (MIIT) as a cultivation base for “specialized, sophisticated, distinctive, and innovative” small and medium-sized enterprises; several of its products have been included in the “Guidance Catalogue for First-Batch Application Demonstration of Key New Materials (2024 Edition).” The Company has delivered customized zeolite catalysts to research institutes and refineries under Sinopec and CNPC; SAPO-34 has achieved large-scale application in MTO units. SCR denitrification catalyst supports are supplied in bulk to leading domestic environmental protection equipment manufacturers. The 13X zeolite for hydrogen purification and specialized CO₂ adsorption zeolites have completed pilot-scale verification and entered the customer integration phase. Its business covers over 20 provinces, municipalities, and autonomous regions nationwide, with primary customers concentrated in East China, North China, and Northeast China. International operations are in the initial expansion stage, with samples already exported to South Korea, India, and certain Middle Eastern countries. The Company is open to diverse forms of collaboration with upstream and downstream industrial chain partners, including technical cooperation, customized development, joint research efforts, and industrialization support.
