Honeycomb Zeolite

Technology Introduction

1. The main material of honeycomb molecular sieve is natural zeolite, an inorganic microporousmaterial composed of SiO2, Al2O3, and alkali metals or alkaline earth metals;

2. It has uniform micropores, with pore sizes comparable to general molecular sizes, an internal pore volume accounting for 40-50% of the total volume, and a specific surface area of 300-1000 m2/g;

3. Due to the uniform pore size distribution, significant variations in structure and composition, it features high temperature resistance, non-flammability, good thermal stability, and hydrothermal stability.

Working Principle

The desorption uses hot air as the desorption medium, and this hot airflow comes entirely from the residual heat after catalytic combustion within the system. The concentrated organic waste gas after desorption enters the catalytic combustor for purification treatment, requiring no additional energy, greatly reducing operating costs. For the same treatment volume, it is about 1/20 of the direct catalytic combustion method and 1/10 of the molecular sieve adsorption.

Desorption Methods

⑴ Offline Desorption

This method involves manually transferring the adsorption-saturated molecular sieve to a specialized desorption device located in a safe area for desorption. During molecular sieve

desorption, it is completely separated from the pipelines and adsorption beds in the adsorption system. This method is safe and reliable but involves complicated operations.

⑵ Online Desorption

When the molecular sieve is saturated, the adsorption/desorption valve switches its working state directly, then hot air is used to desorb the adsorption bed.
