Introduction

1. Background of standard formulation and analysis of technical evolution

With the increasing global attention to environmental protection, nitrogen oxide (NOx) emissions from marine diesel engine exhaust have become a focus of attention. Selective catalytic reduction (SCR) technology, as an efficient denitrification method, is widely used in the field of marine engines. The formulation of this standard GB/T 37352-2019 aims to standardize the product quality and technical requirements of marine SCR honeycomb denitrification catalysts to ensure their effectiveness and reliability in marine diesel engine exhaust treatment systems.

2. Comparison of standard frameworks

Standard Dimensions	GB/T 37352-2019	Comparison Standards
Terms and Definitions	The definitions of key terms such as units and modules are clarified.	It is consistent with GB/T 33104-2016, and the specific requirements for honeycomb catalysts are supplemented.
Product specifications	The recommended number of holes is 25-50 holes/square inch.	The flexibility requirements for module assembly methods have been increased.
Technical requirements	Include key indicators such as unit appearance, geometric dimensions, and compressive strength.	Added specific parameters for aging tests and vibration tests to ensure the stability of catalysts in actual applications.

3. Implementation suggestions

Choose the appropriate catalyst model: According to the power and exhaust conditions of the ship diesel engine, reasonably select the number of holes and specifications. For example, it is recommended to use a catalyst with 40 holes or higher density under high load conditions.

Strictly follow the test methods:In the factory inspection and type inspection, focus on key indicators such as denitrification efficiency, compressive strength and specific surface area to ensure that product quality meets the standard requirements.

Pay attention to installation and maintenance:The installation of the catalyst module should follow the technical manual provided by the manufacturer, especially the volume change requirements after the vibration test, and the status of the catalyst should be checked and recorded regularly.
