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™ رغوة الميلامين 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:

الهواء المحيط
↓
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:

• Sorbent Carrier
• Porous Scaffold
• دعم منظم
• إطار عمل أحادي الأبعاد

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

و

مقاومة منخفضة لتدفق الهواء

SINOYQX™ open-cell رغوة الميلامين is being evaluated as a potential architecture for:

Low-Pressure-Drop Sorbent Support

Future development can focus on:

• نفاذية الهواء
• هبوط الضغط
• سرعة الهواء
• بنية المسام
• سمك الرغوة
• Sorbent loading
• Sorbent distribution
• Mass-transfer efficiency

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.

قد تتضمن العملية النموذجية ما يلي:

CO₂ Adsorption
↓
Sorbent Saturation
↓
تجديد
↓
إطلاق ثاني أكسيد الكربون
↓
Sorbent Reuse

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

The support structure and other inactive components may also absorb heat.

Parasitic Thermal Load

SINOYQX™ standard melamine foam has a typical density of approximately:

8.5 كجم / م XNUMX

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

تشمل الفوائد المحتملة ما يلي:

• Improved sorbent utilization
• Greater gas-solid contact
• Lower inactive structural fraction
• Reduced module weight
• تحسين كفاءة المواد
• More compact sorbent architecture

The objective is to use less structural material while supporting more active capture chemistry.

Key Performance Parameters to Validate

This application should currently be treated as a:

Joint Development Concept

rather than a fully validated commercial DAC product.

The following parameters should be evaluated together with the sorbent developer.

Sorbent Loading

Determine how much active sorbent can be retained per:

• Foam mass
• Foam volume
• وحدة تخزين

while maintaining acceptable airflow and mechanical stability.

CO₂ Uptake

Evaluate both:

CO₂ / Sorbent Mass

و

CO₂ / Module Volume

to understand both material-level and module-level performance.

هبوط الضغط

Establish performance curves across different:

• Foam thicknesses
• Pore structures
• Sorbent loadings
• Air velocities

The goal is to generate:

Air Velocity vs. Pressure Drop

data for contactor design.

Sorption Kinetics

يقيم:

• معدل الامتصاص
• Desorption rate
• Breakthrough behavior
• Mass-transfer performance

الكتلة الحرارية

السؤال الرئيسي هو:

How much inactive material must be heated and cooled during each regeneration cycle?

استقرار ركوب الدراجات

• Foam fatigue
• Sorbent shedding
• تشكيل المسحوق
• Pore structure changes
• الاستقرار الأبعاد

Additional Application: Thermal Insulation in DAC Systems

Melamine foam may also be evaluated for a second, more conventional role within DAC infrastructure.

Potential insulation locations include:

• Regeneration equipment
• الأنابيب عملية
• قنوات التدفئة
• CO₂ processing equipment
• حاويات المعدات

By reducing unnecessary heat loss, thermal insulation can support lower heating demand within DAC equipment.

This application is separate from the sorbent-support concept and is closer to established industrial insulation use cases.
