The development of new technologies for the synthesis green ammonia using exclusively hydrogen from water and nitrogen air in processes driven by renewable energy is poised to decarbonize production this important molecule fertilizers as well offering a carbon-free vector long-term storage energy. In article, we explore quantify CO 2 emission reduction potential ammonia, evaluating how it can facilitate decarbonization other hard-to-abate industrial such steel, glass cement industries. Green be used direct replacement fossil fuels sources different processes. addition, electrification (so-called Power-to-X) storing long term balance decarbonized grid against intermittent supplies. This article part discussion meeting issue ‘Green carbon chemical industry future’.

Performance Evaluation and Analysis of a Coal-Fired Power Plant Coupled with a Liquid Carbon Dioxide Energy Storage System

Опубликована: Янв. 1, 2024

Facing the peak regulation for electrical network in new power systems, addition of energy storage system can improve operational flexibility coal-fired plants (CFPPs). This paper proposes CFPP coupled with a liquid carbon dioxide (LCES) system, and assesses four different coupling schemes. The performance optimal is evaluated by energy, conventional exergy advanced analyses. By comparing integrated under integration methods, it found that best facilitated using steam turbine fifth-stage extraction as source LCES system. analysis shows round-trip efficiency subsystem 65.16%, which 6.99% improvement over single cold tank are two components largest destruction, accounting 21.90% 20.37%, respectively. total endogenous avoidable destruction account 96.18% 55.04%, suggests mainly from themselves modifications to help performance. Besides, sensitivity reveals increasing compressors turbines an effective way performance, however, compression ratio either compressor or will result lower may provide ideas CFPPs.

Unraveling the Role of Intrinsic Carbon Defects for the Heterogeneous Reduction of NO with NH ₃

Combustion Science and Technology, Год журнала: 2024, Номер unknown, С. 1 - 17

Опубликована: Авг. 27, 2024

This study investigates the impact of intrinsic carbon defects on reduction nitrogen oxides (NOx) during coal combustion, with a focus synergistic effect ammonia (NH3) and pulverized coal. Two representative computational models containing are described, their influence NH3 NO is studied. Stable species transition states present in pathways calculated using B3LYP/6-31 G(d). Results indicate that exposed edge atoms exhibit higher charge density distribution, affecting adsorption reduction. The maximum energy barriers for both do not exceed 45 kcal/mol, achievable practical combustion systems. paper also calculates heterogeneous process model without (Char model), aim observing specific effects processes migration H/O atoms, recombination N formation desorption N2 molecules. Furthermore, analyses demonstrated an increase rate defective surfaces comparison to Char/NH/NO system, indicating have contributory catalytic activity. With regard magnitude reaction increasing temperature, presence base serves reinforce role temperature rate-determining step. Overall, this provides insights into carbon-based catalysis offers implications oxide emission control strategies.
