	TZ-A Series Adsorbents The TZ-A series is a range of adsorbents specially developed by our company for the coke oven gas pressure swing adsorption (PSA) hydrogen production process. This series includes PSA-exclusive silica gel, activated alumina, hydrogen production molecular sieves, and activated carbon. Among them, the molecular sieve (TZ-A0301) is a flagship product. Under optimal process conditions, this adsorbent can achieve a hydrogen purity of 99.9999%.Application: Coke oven gas PSA hydrogen production process.
	TZ-B Series Adsorbents The TZ-B series is designed for the precise removal of impurities such as tar, naphthalene, benzene, and sulfur from coke oven gas. It offers multiple models that can be combined with corresponding processes to meet customers' varying requirements for purified gas. The precision naphthalene removal adsorbent is a commonly used product, capable of reducing naphthalene content to 1 mg/Nm³ under appropriate process conditions.Application: Coke oven gas temperature swing adsorption purification process.
	TZ-C Series Adsorbents The TZ-C series is a high-temperature and high-pressure resistant adsorbent developed specifically for pressure swing adsorption and temperature swing adsorption processes. These products can optimally regulate PSA and TSA process parameters, protect key adsorbents for long-term use, and ensure operational safety. The series is available in multiple specifications, with TZ-C0101 as a representative product.Application: Pressure swing adsorption and temperature swing adsorption processes.
	TZ-D Series Adsorbents The TZ-D series is a range of adsorbents specially developed by our company for the coke oven gas temperature swing adsorption (TSA) process. These products are used for the preliminary purification of coke oven gas, featuring exceptional adsorption performance for tar and the ability to optimally regulate inlet gas flow distribution. The series includes multiple specifications, with TZ-D0101 (polymer activator-impregnated adsorbent) as a representative product.Application: Preliminary purification of coke oven gas via temperature swing adsorption.
	TZ-H Series Adsorbents The TZ-H series is designed exclusively for pressure swing adsorption (PSA) hydrogen production units. It primarily consists of 5A molecular sieves and 13X molecular sieves, with the 5A molecular sieve (TZ-H0302) as a flagship product. Under optimal process conditions, this adsorbent can achieve a hydrogen purity of 99.9999%.
	TZ-P Series Adsorbents The TZ-P series encompasses a variety of catalysts developed for chemical production processes. This series includes multiple products, with TZ-P0201 as a representative product—a palladium catalyst specifically engineered for deoxygenation processes.Application: Deoxygenation processes.
	TZ-T Series Desulfurizers The TZ-T series desulfurizer is a high-efficiency solid desulfurizer for removing hydrogen sulfide (H₂S) at ambient temperature. It is widely used for H₂S removal from natural gas, oilfield associated gas, and other gas sources. It can operate at ambient temperature, under normal or pressurized conditions, and features high sulfur capacity, high purification efficiency, and strong adaptability.Application: Dry desulfurization processes.
	TZ-ET New High-Efficiency Desulfurizers The TZ-ET new high-efficiency desulfurizer series uses high pore volume activated carbon as a carrier, incorporating weak alkaline substances and nitrogen doping to selectively catalyze the oxidation of H₂S for targeted removal. It boasts an exceptional sulfur capacity of 50–90%, enabling high-precision desulfurization at high space velocities, with a desulfurization accuracy of ≤ 1.0 mg/Nm³. Additionally, these desulfurizers are renewable.
	TZ-SJ Type Adsorbents The TZ-SJ hydrolysis catalyst is a high-performance catalyst developed by Shanghai Tongtong Chemical Technology Co., Ltd. specifically for the hydrolytic conversion of organic sulfur impurities (mainly carbonyl sulfide (COS) and carbon disulfide (CS₂)) in coke oven gas. This catalyst series offers stable performance, high hydrolysis efficiency, low energy consumption, and fast conversion rates. Under optimal process conditions, it achieves a COS conversion rate of ≥ 98% and a CS₂ conversion rate of ≥ 80%.
