It is widely used as feedstock for fertilizers, industrial chemicals, and emission after-treatment systems. Owing to its properties, ammonia has garnered interest as a carrier for hydrogen in energy applications. It can be generated from carbon-free emission sources and pyrolyzed to produce pure hydrogen for various applications. The combustion of ammonia for power generation has been previously reviewed in this journal besides several aspects of ammonia oxidation chemistry, as it relates to emission after-treatment and reburn systems. However, the pyrolysis and oxidation chemistry of ammonia requires further elucidation to improve its use as a hydrogen carrier and as a fuel for combustion systems. This article provides an in-depth review of ammonia pyrolysis and oxidation chemistry in noncatalytic and catalytic systems. The catalytic pyrolysis chemistry of ammonia to produce pure hydrogen is reviewed to understand catalyst and reactor requirements for scaling up this technology. The combustion properties of ammonia as a pure fuel and in mixtures, including ignition, flame propagation, and extinction characteristics; its pyrolysis and oxidation reactions; and its potential to produce pollutant emissions are extensively reviewed. Ammonia combustion reaction mechanisms are reported based on results from pyrolysis and oxidation reactors, shock tubes, rapid compression machines, and research engines. The experimental work is complemented by the development of detailed combustion models via chemical kinetic and quantum chemistry simulations. Herein, recent results on ammonia pyrolysis and oxidation chemistry are introduced and summarized by highlighting the pertinent aspects of this rich and rapidly increasing body of information.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"105 ","pages":"Article 101177"},"PeriodicalIF":32.0,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142049668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CO₂ capture and utilization (CCU) captures anthropogenic waste CO₂ and valorizes it into useful products, supporting a circular transition pathway towards carbon neutrality. Unfortunately, the thermodynamic stability of CO₂ requires a high-energy input for its conversion, resulting in processes with a net positive carbon footprint. The incorporation of enzymes as biocatalysts in a process is attractive, as it facilitates CO₂ conversion under ambient conditions. In Nature, the conversion of CO₂ into organic compounds is done through photosynthesis, using an enzyme called ribulose-1,5-biphosphate carboxylase/oxygenase (RuBisCO). RuBisCO plays a central role in the natural assimilation of CO₂, making it the enzyme chosen in Nature upon which all life forms depend. However, the slow carboxylation rate of RuBisCO (1–10/s) has caused it to be overlooked by faster enzymes such as carbonic anhydrase (CA), which has a carboxylation rate of 10⁶/s. Despite this, RuBisCO has a rate enhancement of 10⁸ to 10¹⁰ times higher than CA. Thus, this review aims to take a closer look at RuBisCO and examine its potential in CCU. Various aspects are considered, such as RuBisCO’s performance in comparison to other enzymes, approaches to overcome its limitations, its applications and implications in CCU, the valuable chemicals that can be derived from it, recent developments in RuBisCO-integrated processes, and its economic and environmental considerations. Through this, RuBisCO’s potential as one of the key enzymes in CCU will be explored.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"105 ","pages":"Article 101184"},"PeriodicalIF":32.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141979773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model has been developed and applied to a wide range of combustion regimes, including diffusion, premixed, stratified premixed, mixed-mode combustion in lifted flames, spray combustion and MILD combustion in the past two decades. It has been tested against several Direct Numerical Simulation (DNS) databases in <em>a priori</em> analyses and also coupled with both Large-Eddy Simulation (LES) and Reynolds-Averaged Navier–Stokes (RANS) flow solvers to simulate benchmark burners. The CSE model has also been used in the simulation of practical combustion devices such as internal combustion engines and industrial furnaces.

Key structure-function aspects are explored across various MOF-derived materials, encompassing the impact of metal identity, organic linker chemistry, porosity, defect concentration, and particle morphology.

A basic understanding of this phenomenon is crucial for fire safety control and for the development of advanced combustion engines. Significant efforts have been devoted to understanding the mechanisms of ignition and determining critical ignition conditions, such as critical flame radius, minimum ignition energy, and minimum ignition power, which have remained challenging research topics for centuries. This review provides an in-depth investigation of the forced-ignition of laminar premixed flames in a quiescent flammable mixture, with emphasis on theoretical developments, particularly those based on activation energy analysis. First, the fundamental concepts are overviewed, including spark ignition, characteristic time scales, and critical ignition conditions. Then, the chronological development of premixed flame ignition theories is discussed, including homogeneous explosion, thermal ignition theory, flame ball theory, quasi-steady ignition theory, and, more importantly, transient ignition theory. Premixed flame ignition consists of three stages: flame kernel formation, flame kernel expansion, and transition to a self-sustaining flame. These stages are profoundly affected by the coupling of positive stretch with preferential diffusion, characterized by the Lewis number. Specifically, positive stretch makes the expanding ignition kernel weaker at larger Lewis numbers, consequently increasing the critical ignition radius and MIE. The premixed flame ignition process is dominated by flame propagation dynamics. Both quasi-steady and transient ignition theories demonstrate that the critical flame radius for premixed ignition differs from either flame thickness (by thermal ignition theory) or flame ball radius (by flame ball theory). Particularly, the transient ignition theory appropriately acknowledges the “memory effect” of external heating, offering the most accurate description of the evolution of the ignition kernel and the most sensible evaluation of minimum ignition energy. In addition, the effects of transport and chain-branching reactions of radicals, finite droplet vaporization, and repetitive heating pulses on premixed flame ignition are discussed. Finally, a summary of major advances is provided, along with comments on the applications of premixed flame ignition theory in ignition enhancement. Suggested directions for future research are presented.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"104 ","pages":"Article 101174"},"PeriodicalIF":32.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141596744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, thermal energy charging and discharging are restricted due to the low conducting nature of the energy storage medium. Various research investigations are being carried out to improve the thermal characteristics of PCMs through techniques such as a) dispersion of nanoparticles, b) inserting fins, and c) cascading PCMs. Among the techniques mentioned above, the dispersion of nanoparticles is reliable and economically viable.

This paper presents a comprehensive review with implications and inferences on research conducted using nano-enhanced phase change materials (NePCMs) in recent years. Initially, the article discusses the highly preferred synthesis methods of NePCMs in addition to its morphological and thermophysical characterization techniques. Then, an acute focus on the impact of distinct dimensional nano additives like zero-dimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) on inclusion with PCMs are elaborately discussed.
