A commercially available sorbent, commonly used in packed bed configurations, is selected as the benchmark sorbent, while a monolithic geometry is also examined to assess its potential performance. The process is modelled using Aspen Adsorption and incorporates physico-chemical data in DAC environmental conditions, including binary isotherms under humid condition. In a reference case comparing the two geometries, the packed bed exhibits higher productivity (2.4 kgCO₂/(h.m³)), while the monolith achieves 1.2 kgCO₂/(h.m³). However, the monolith allows for a significant reduction in pressure drop and associated fan work by about two orders of magnitude. These findings highlight the trade-off between productivity in favor of packed bed and energy requirement in favor of monolithic design. A sensitivity analysis is then conducted on various environmental and process parameters such as sorbent and bed dimension, air velocity, temperature and humidity, adsorption/desorption loading, mass transfer kinetic, and regeneration pressure, temperature, and steam flowrate.

China has pledged the dual carbon goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060, underscoring the urgency and scale of the challenge. While Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising approach, its large-scale implementation in emission-intensive industrial clustered region faces significant infrastructural challenges. Specifically, the optimal layout of regional CCUS clusterization and CO₂ transport networks remains unclear, particularly in highly industrialized regions such as China’s Jiangsu Province, where diverse industrial sectors and varied geological formations create complex source-sink matching challenges for CCUS deployment. In this study, we developed the SPATIAL (Strategic Pipeline And Technical Integration Analysis Layout) model that enables the optimization of CCUS deployment in emission-intensive regions from an industrial cluster perspective by integrating data of emissions from major industrial sources and storage potential from geological formations. The model was applied to Jiangsu Province under high, medium, and low emission reduction target scenarios through source-sink matching. Results show significant spatial heterogeneity between emission sources and geological storage resources in Jiangsu Province. For example, southern Jiangsu, characterized by high-intensity CO₂ emission clusters, accounts for 63 % of the province’s total emissions while holding only 0.03 % of the province’s geological storage potential. The optimal layout for regional CCUS clusterization deployment under high, medium, and low emission reduction targets achieve total CO₂ storage of 1.4, 1.1, and 0.9 Gt, respectively, supported by pipeline networks of 4629, 2513, and 1433 km. These layouts demonstrate economies of scale, with unit emission reduction costs ranging from 93.84 to 179.31 CNY/t CO₂. Our findings establish the technical and economic feasibility of achieving significant emission reductions through regional CCUS clusterization deployment and address a critical gap in ignoring the hot spot phenomenon of industrial cluster. This study further emphasizes the importance of inter-regional coordination, regional geological storage resource management, and integrated infrastructure planning in realizing cost-effective CCUS clusterization implementation. This study provides policymakers with actionable insights for formulating CCUS clusterization strategies in emission-intensive industrial regions, contributing to the broader goal of regional carbon neutrality.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"17 ","pages":"Article 100495"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145020149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a thermal FBR was developed, and catalytic DRM was systematically evaluated. Nickel-supported catalysts (Ni/FCC) were prepared via a wet impregnation method using commercial fluid catalytic cracking (FCC) particles, and their physicochemical properties were comprehensively characterized. Detailed fluidization behaviour was investigated using pressure drop fluctuations and discrete wavelet transformation (DWT), revealing a transition velocity (Uc) between bubbling and turbulent regimes in the FBR (under the conditions relevant to DRM), which was found to decrease with increasing temperature. DRM performance of Ni/FCC was assessed under various reaction temperatures (600–800 °C), gas velocities (0.1–0.2 m/s), and preheating conditions. Optimal operation in the bubbling regime (800 °C, 0.1 m/s) enabled CO₂ and CH₄ conversions of 57% and 41%, respectively, with an H₂/CO ratio of 0.67. Comparative studies demonstrated that the packed bed reactor (PBR) achieved higher conversions and better H₂/CO ratios (∼0.96), attributed to its plug flow characteristics, whereas the FBR exhibited lower conversions due to gas back mixing and reactant bypassing. Nevertheless, the Ni/FCC catalyst exhibited good thermal stability and negligible deactivation in both reactor configurations during 20 h of continuous operation.

In addition, negative emissions by permanently removing carbon dioxide from the atmosphere are required. Both targets require substantial amounts of carbon neutral electricity and heat production. While electricity can be produced and transferred over long distances, the heat production needs to be local. This study investigates an energy system integrating both carbon neutral heat production and carbon dioxide removal from the atmosphere. The system is modelled using the Backbone energy system modelling framework. The carbon neutral heat production in the study is based on small modular nuclear reactors (SMRs), large-scale thermal energy storages (TES), heat pumps (HPs) and electric boilers (EBs), and the carbon removal is implemented by direct air capture (DAC) combined with permanent geological storage. The studied technologies are integrated into a specific large-scale district heating system located in Northern Europe. The impact of outdoor temperature for the efficiency of the DAC process is considered, and the system integration potential with the district heating system is evaluated. The results show that high 70–90 % utilisation rates for both SMR and DAC units can be reached but depending on the case year and corresponding profiles for demand, outdoor temperature, electricity and carbon prices, a large variation in utilisation rates is observed. The variable CO₂ capture costs were between 115–126 €/t CO₂ in the modelled scenarios, and with higher OPEX values at the range 152–163€/tCO₂, and the limit price for economic viability considering the investment was calculated to be in the range of 209–223 €/tCO_2, with lower, and 233–246 €/tCO₂ with higher adsorbent costs.
