Introduction

With increasingly stringent environmental protection requirements, the importance of flue gas denitrification technology in the industrial field has increased significantly. GB/T 35209-2017 "Technical Specification for Regeneration of Flue Gas Denitrification Catalysts" provides clear technical guidance for the determination, detection and application of regenerated catalysts, aiming to improve resource utilization efficiency and reduce environmental pollution.

Background of Standard Formulation

This standard was proposed by the China Petroleum and Chemical Industry Federation and is managed by the National Technical Committee for Chemical Standardization. Its drafting units include Datang Nanjing Environmental Protection Technology Co., Ltd., Zhejiang DeChuang Environmental Protection Technology Co., Ltd. and other industry-leading companies, fully reflecting the advantages of combining industry, academia and research.

Interpretation of Technical Specifications

GB/T 35209-2017 specifies the terms and definitions, regeneration determination rules, regeneration steps and detection methods for flue gas denitrification catalyst regeneration. The following is a professional analysis of the key contents:

Dimensions	Technical requirements	Implementation points
Renewable determination rules	Unit appearance, physical and chemical properties	Must meet the index requirements of Table 1 and Table 2
Regeneration steps	Cleaning, chemical cleaning, ultrasonic cleaning and other process flows	Flexibly adjust the plan according to the cause of catalyst deactivation
Detection method	Appearance inspection, physical and chemical properties test, reaction performance determination	Must refer to GB/T 31584 and GB/T 31587 and other standards

Professional term analysis and practical application cases

Deactivated Catalyst: refers to the flue gas denitrification catalyst whose activity has been attenuated due to physical or chemical factors. For example, after long-term operation, the catalyst surface is covered with dust, causing its pores to be blocked, and regeneration is required.

Catalyst Regeneration: The process of restoring the performance of deactivated catalysts through physical and chemical methods. For example, ultrasonic cleaning technology is used to remove blockages in the catalyst pores, thereby restoring its activity.

Comparative analysis of standard frameworks

The following is a comparative analysis of GB/T 35209-2017 and international advanced standards:

Dimensions	GB/T 35209-2017	International standards (such as EN 16731)
Judgment rules	Based on unit appearance and physical and chemical performance indicators	Emphasis on catalyst activity recovery rate and mechanical strength
Regeneration process	Cleaning, chemical cleaning, ultrasonic cleaning, etc.	High-pressure cleaning, high-temperature roasting, etc.
Testing methods	Refer to GB/T series standards	Adopt ISO international general test methods

Implementation suggestions

In order to ensure the effective implementation of the technical specifications for flue gas denitrification catalyst regeneration, the following suggestions are put forward:

Enterprise level:Establish a sound regeneration process management mechanism and equip professional testing equipment and personnel.
Industry level:Strengthen standard publicity and technical training to promote industry technical exchanges and cooperation.
Policy level:Introduce supporting incentive policies to encourage enterprises to adopt green regeneration technology.

Conclusion

The implementation of GB/T 35209-2017 will significantly improve the resource utilization efficiency of flue gas denitrification catalysts and reduce environmental pollution. Through scientific judgment, standardized regeneration process and strict testing, we can ensure that the quality and performance of the regenerated catalyst meet the expected requirements.
