Melamine Foam for Direct Air Capture
Lightweight 3D Sorbent Support for Low-Energy Carbon Removal Systems
Direct Air Capture (DAC) technologies are moving beyond sorbent chemistry alone.
As DAC systems scale, engineers must also address how large volumes of ambient air move through the capture structure, how much inactive structural mass must be heated during regeneration, and how effectively the sorbent is distributed throughout the contactor.
SINOYQX™ is exploring open-cell melamine foam as a:
Lightweight 3D Sorbent Support
for next-generation Direct Air Capture systems.
In this concept, melamine foam does not capture CO₂ by itself.
Instead, it serves as a lightweight porous carrier that can potentially support specialized CO₂ sorbents within a three-dimensional open-cell structure.
Why DAC Needs More Than Better Sorbents
Ambient air contains a relatively low concentration of CO₂.
To remove meaningful quantities of carbon dioxide, DAC systems must therefore process very large volumes of air.
This means that system performance depends not only on:
How much CO₂ can the sorbent capture?
but also on:
How efficiently can air reach the sorbent?
If the sorbent structure creates excessive airflow resistance, the system may require higher fan power and greater electrical energy input.
At the same time, if the sorbent is supported on heavy metal, ceramic or other structural materials, these inactive components may also need to be repeatedly heated and cooled during regeneration.
For next-generation DAC systems, the engineering challenge is therefore increasingly becoming:
Sorbent Chemistry + Sorbent Architecture
3D Open-Cell Sorbent Architecture
SINOYQX™ меламин көбігі features a continuous three-dimensional open-cell structure.
Unlike a conventional two-dimensional surface, air can move through the internal porous network of the foam.
This creates an opportunity to study sorbent coatings, impregnation and surface-functionalization methods that distribute active capture materials throughout the structure.
A potential configuration could be:

3D Open-Cell Melamine Foam
↓
CO₂ Sorbent Distributed on the Foam Skeleton

Gas-Solid Contact
↓
CO₂ Capture by the Active Sorbent
↓
Remaining Air Continues Through the Structure
In this system, the melamine foam acts as:
The active CO₂ capture function remains with the specialized sorbent chemistry.
Potential Benefit 1: Lower Airflow Resistance
Supporting Low-Pressure-Drop DAC Contactor Design
Direct Air Capture requires large-volume air handling.
For this reason, pressure drop is an important system-level engineering parameter.
A highly dense contactor structure may provide a large surface area but can also increase airflow resistance.
The goal is therefore not simply to maximize surface area.
The real engineering objective is to find a balance between:
Effective Gas-Solid Contact

SINOYQX™ open-cell меламин көбігі is being evaluated as a potential architecture for:
Low-Pressure-Drop Sorbent Support
Future development can focus on:
The key relationship to characterize is:
Air Velocity vs. Pressure Drop
under realistic sorbent-loading conditions.
Potential Benefit 2: Ultra-Low Structural Mass
Reducing Inactive Thermal Load During Regeneration
Many Direct Air Capture processes operate through repeated adsorption and regeneration cycles.

During thermal regeneration, the energy input does not only heat the sorbent itself.

Parasitic Thermal Load
SINOYQX™ standard melamine foam has a typical density of approximately:
8.5 кг / м³
Its very low structural mass makes it a candidate for evaluation as an:
Ultra-Low-Thermal-Mass Sorbent Support
The potential engineering pathway is:
Lower Support Mass
↓
Lower Inactive Structural Heat Capacity
↓
Less Non-Active Material Repeatedly Heated During Each Cycle
↓
Potentially Lower Regeneration-Related Energy Demand
The final performance metric should not simply be material weight.
The relevant system-level metric is:
Energy Consumption per Ton of CO₂ Captured
Potential Benefit 3: More Active Sorbent per Unit Structural Mass
Traditional planar substrates mainly support active material on an external surface.
A three-dimensional porous scaffold offers the possibility of distributing sorbent throughout an internal network.
This creates an opportunity to explore:
More Active Surface per Unit Structural Mass
