01 Professional Team, Sincere Service

Every colleague served the customers seriously, they listened carefully to customers’ inquiries and accurately solve their concerns. From basic activated carbon knowledge to detailed application in the equipment, their professional detailed explanation had won widely praise by customers! 

02 Technical Exchange, Win-win Cooperation

HANYAN had shared experience on VOCs treatment in the exhibition in meeting hall with topic Analysis of Activated Carbon Specifications for VOCs Treatment and Its Influence on Adsorption Performance, in order to help customers to know more technologies knowledge and correctly select activated carbon and use it effectively. What’s more, our vice president, Jane, was invited by HB for an interview. In the interview, Jane had introduced our company, products and also specifications analysis of activated carbon.

03 Innovative Product, First Show

In response to the policy call of the National Environmental Protection Bureau, HANYAN actively researches and develops high-end quality activated carbon. At present, we has successfully developed and mass produced honeycomb activated carbon with CTC≥75% and Iodine value≥800mg/g, which meets the environmental protection standard, and has made great contribution to the application of gas phase adsorption of VOCs treatment.

Honeycomb Activated Carbon Engineering Guide

Honeycomb Activated Carbon Engineering Guide

This engineering guide consolidates key technical principles behind honeycomb activated carbon performance, including airflow resistance, CPSI, contact time, and breakthrough behavior. Designed for industrial gas-phase filtration professionals, it provides a structured framework for system-level evaluation and optimization.

Why CPSI Alone Cannot Define Honeycomb Activated Carbon Performance

This article explains why CPSI (cells per square inch) should not be treated as a standalone performance indicator for honeycomb activated carbon filters. By examining airflow behavior, contact time, adsorption kinetics, and carbon utilization, it highlights the limitations of CPSI-only comparisons and provides a more practical engineering perspective for industrial gas-phase filtration design.
