One of the key environmental problems underlying climate change and global warming is persistent increase in atmospheric carbon dioxide concentration. Carbon capture storage (CCS) systems can be based on, among others, solid porous sorbents (e.g., zeolites). A promising alternative to traditionally used may appropriately structured hybrid adsorbents. With proper geometry synergistic combination sorbent with another material, e.g., a catalyst or substance certain useful physical features, they gain new properties. The present study examined dynamics CO2 sorption core–shell particles and, as reference, uniform structure. It was assumed that (zeolite 5A) incorporated single particle had form microcrystals, which implies bidisperse As second particle-forming nickel (behaving an inert) adopted. computational results confirmed structure provide additional design parameter for adsorption columns adsorptive reactors. sorption-inactive shell proved play protective role when thermal waves moved through bed. In addition, important element determining revealed mean pore diameter) controlling intraparticle mass transport.

Limiting the carbon intensity of maritime transport is crucial to meet 2050 net-zero targets. Onboard capture and storage (OCCS) offers a practical short-term solution for reducing shipping-related CO2 emissions until cleaner technologies are ready large-scale adoption. This study introduces an innovative multi-objective approach integrate sustainability into conceptual design decision-making phases OCCS. A systematic technology screening identified possible OCCS solutions, which were then assessed onboard feasibility. Specific indicators defined evaluate performance based on technological, economic, environmental, social criteria, aggregated perspectives. Using fossil fuel-powered cruise ship as case study, results benchmarked against zero-carbon alternatives. Among alternatives considered, chemical absorption by amine scrubbing (AS) advanced cryogenic (A3C) appeared only feasible solutions considering energy requirements. The emerging A3C concept resulted in being outperformed benchmark AS, primarily due environmental impact 1.5 times higher. All alternative technologies, whether OCCS- or fuel-based, found be more sustainable than baseline fuel-based engine, lowering at least 61%. Hydrogen marine fuel leads most promising scenario future shipping operations, footprint up 76%. robustness proposed method was confirmed probabilistic Monte Carlo sensitivity analysis. Overall, obtained can guide toward informed policies promoting propulsion systems.

The increase in atmospheric CO2 caused by human activities has driven the development of technologies to capture this gas before it reaches atmosphere. This study analyzed sorption using amine-based solvents, such as methyldiethanolamine (MDEA), diethylenetriamine (DETA), triethanolamine (TEA), and monoethanolamine (MEA) 40 wt.% aqueous solutions, under high-pressure conditions (initial pressure: 500 psia) room temperature (30 °C), both non-stirred stirred systems. Piperazine (PZ), a heterocyclic compound, was tested an additive improve kinetics process. Kinetic thermodynamic analyses were conducted evaluate efficiency each solution terms reaction rate loading capacity. MEA TEA exhibited higher rates, while DETA MDEA most thermodynamically efficient due highest PZ kinetic behavior depended on equipment used; system, no effect observed, appreciable. Additionally, corrosivity revealed that MEA, primary amine, corrosive, whereas TEA, tertiary least corrosive.
