Dr. Yonit Boguslavsky & Dr. Maria Alesker, R&D, Dotz Nano

As a solid sorbent start-up, our journey in developing a post-combustion CO2 capture solution has been a rollercoaster of learning and innovation. Beginning with synthesis, where novel materials are meticulously crafted, we progress through characterization, shaping, and into the critical phases of kinetics, stability studies and model validation. Here is a walkthrough of our experience in developing a new solid sorbent, offering insights into the systematic approach we’ve taken to contribute to the evolving landscape of carbon capture solutions:

From Concept to Composition: Solid Sorbent Synthesis

In the initial development phase of solid sorbents for carbon capture, the synthesis process emerges as a critical cornerstone, laying the foundation for our journey toward cost-effective, sustainable and energy-efficient post-combustion CO2 capture technology. With a focus on robustness and high yield, we have meticulously refined a synthesis procedure that consistently yields the desirable material for carbon capture applications. The outcome of this stage is a finely crafted porous material presented in powder form. While this powdered substance isn’t yet ready for real-world applications, it serves as a pivotal starting point for further exploration and characterization.

In-Depth Characterization of Sorbent Properties

In the crucial stage of characterization, we delved into a comprehensive examination of key properties essential for effective carbon capture. Through a series of rigorous tests, we assessed the material’s CO2 uptake capacity, ensuring it meets the desired efficiency criteria. Drawing on insights from various sources in the field of sorbent development, we also scrutinize its selectivity towards other gases, a crucial factor for real-world flue gas applications where a multitude of gases may be present. Additionally, our characterization process involved an in-depth analysis of surface area and pore size distribution, essential parameters influencing solid adsorbent performance. By employing techniques such as BET analysis, we gained a nuanced understanding of the material’s structural intricacies.

Form Follows Function: Shaping Our Next-Gen Sorbent

This stage includes the task of determining the optimal form that our material should take for seamless integration into point-source carbon capture systems. Through thoughtful consideration and experimentation, we explore various shapes such as pellets and beads, aiming to identify the configuration that maximizes the sorbent’s efficiency within the intended application. This stage involves not only shaping the material but also revisiting key characteristics through repeated testing. By conducting assessments of CO2 uptake, selectivity towards other gases, and analyzing surface area, pore size, and distribution post-shaping, we gain crucial insights into how the shaping influences the sorbent’s performance. This stage ensures that our shaped sorbent aligns with the optimal criteria for effective carbon capture.

Navigating Gas Flow Dynamics and Process Modeling in Sorbent Kinetics Studies

In the Kinetics Studies stage, our focus shifts towards evaluating the dynamic behavior of gas flow through the sorbent pellets, a pivotal step in understanding the sorbent’s real-world sweet-spot application. This phase involves not only experimental assessments but also sophisticated process modeling, aimed at identifying the optimal conditions for maximizing the sorbent’s efficiency. By comprehensively modeling various scenarios, including different flue gas compositions, we aim to pinpoint the most effective processes that align with our sorbent pellets’ characteristics. This iterative approach ensures not only a fundamental understanding of the kinetics involved but also guides us toward refining the overall carbon capture process. Through this stage, we bridge the gap between laboratory synthesis and practical implementation in post-combustion CO2 capture, propelling our sorbent technology closer to real-world conditions.

Stability Studies: Assessing Sorbent Longevity in Carbon Capture

In the stability and performance studies stage, our attention turns to the endurance and longevity of our sorbent as we subject it to a series of rigorous adsorption and desorption cycles. This critical phase aims to quantify the sorbent’s resilience over time and repeated use, providing essential insights into its practical applicability in sustained carbon capture scenarios. In this stage, we assess how well our material retains its key properties throughout numerous cycles to determine its economic viability and long-term effectiveness in real-world carbon capture applications. Through a meticulous development process, we strive to ensure that our sorbent not only captures carbon efficiently but does so consistently over an extended operational lifespan.

From Theory to Reality: Small-Scale Validation of Sorbent Performance

In the Model Validation stage, we transition from theoretical considerations to practical validation by constructing a small-scale laboratory system. This critical step involves testing the parameters derived from our models, using specific flue gas compositions to simulate real-world industry conditions. By creating this controlled environment, we seek to confirm the accuracy and reliability of our theoretical predictions, ensuring that our sorbent performs consistently and effectively in a given scenario. This stage acts as a bridge between theoretical development and practical implementation, providing a crucial final validation before advancing our solid sorbent technology toward larger-scale applications.
