Comprehensive study of the low-temperature oxidation chemistry by synchrotron photoionization mass spectrometry and gas chromatography

Qiang Xu et al.

Summary: The study developed a JSR system coupled with SVUV-PIMS and GC analysis, which allows for complementary analysis and cross-checking by different methods to improve the accuracy and fidelity of experimental data. This newly developed experimental method enables simultaneous and comprehensive measurement of fuel low-temperature oxidation products, providing a valuable tool for studying fuel low-temperature oxidation chemistry, revealing species pools, and developing combustion models.

Ignition delay time and laminar flame speed measurements of ammonia blended with dimethyl ether: A promising low carbon fuel blend

Gani Issayev et al.

Summary: Ammonia has been recognized as a promising future fuel for mobility and power generation due to its potential to reduce global warming. Blending ammonia with DME can enhance its reactivity, as DME is a highly reactive fuel with zero-carbon emission potential in a sustainable carbon cycle.

Effects of mixture composition on oxidation and reactivity of DME/NH 3 /air mixtures examined by a micro flow reactor with a controlled temperature profile

Yuki Murakami et al.

Summary: The oxidation and reactivity of DME/NH3 mixtures are affected by mixture composition and equivalence ratios. The presence of NH3 in fuel blends promotes DME oxidation up to a certain point, but beyond that, it inhibits CO oxidation and suppresses mixture reactivities strongly. The study demonstrates the potential of NH3 to control reactivity of hydrocarbon mixtures over a wide range by adjusting mixture composition and equivalence ratios.

Experimental and kinetic study on laminar flame speeds of ammonia/dimethyl ether/air under high temperature and elevated pressure

Geyuan Yin et al.

Summary: The study investigated laminar flame speeds of ammonia mixed with dimethyl ether under various conditions, using different kinetic models for validation. Results showed a decrease in NO formation and lower flame speed when co-firing with DME. Comparison of different flame types was also conducted to provide insights into the reactions involved.

An experimental and modeling study of ammonia oxidation in a jet stirred reactor

Ruoyue Tang et al.

Summary: This study investigates the oxidation of ammonia and proposes a chemical kinetic model for ammonia oxidation. The results show that ammonia oxidation is highly reactive under ultralean conditions, with lower temperatures and higher rates of oxidation. However, this reactivity diminishes rapidly with an increase in equivalence ratio, resulting in similar ammonia oxidation characteristics at equivalence ratios of 0.5 and 1.0. The study also analyzes the reaction pathways for different equivalence ratios and oxidation temperatures.

An experimental investigation into the effect of spark gap and duration on minimum ignition energy of partially dissociated NH3 in air

Herry Lesmana et al.

Summary: This paper investigates the effect of spark gap and spark duration on the minimum ignition energy (MIE) of partially dissociated NH3 in air. The results show that increasing the degree of NH3 dissociation significantly reduces the MIE. Moreover, there are optimal spark gap and spark duration for achieving the lowest ignition energy, considering the specific degree of NH3 dissociation and equivalence ratio.

Study of combustion and NO chemical reaction mechanism in ammonia blended with DME

Xiangyu Meng et al.

Summary: This study developed a detailed chemical reaction mechanism and investigated the combustion and emission mechanism for NH3/DME dual-fuel combustion. It was found that fuel NOx still dominates the total NOx production in NH3/DME combustion, and DME addition promotes the NO formation reaction.

Experimental and kinetic modelling studies of flammability limits of partially dissociated NH 3 and air mixtures

Herry Lesmana et al.

Summary: This study investigates the flammability limits of partially dissociated NH3 in air through experimental and kinetic modeling approaches. The results show that the flammability limits widen significantly with increasing degree of NH3 dissociation, leading to wider ranges compared to pure NH3. The production of key radicals like OH, H, O, and NH2 during combustion is enhanced in the presence of H2, contributing to the wider flammability limits observed near LFL and UFL.

Combustion chemistry of ammonia/hydrogen mixtures: Jet-stirred reactor measurements and comprehensive kinetic modeling

Xiaoyuan Zhang et al.

Summary: This study investigates the oxidation of ammonia/hydrogen mixtures at intermediate temperatures using experimental and modeling approaches. The results show that hydrogen blending enhances the oxidation reactivity of ammonia, leading to increased OH radical production and accelerated ammonia consumption. Non-monotonous trends in NOx formation are observed at 99% conversion of ammonia, influenced by the competition between dilution and chemical effects of hydrogen addition.

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations

Liming Dai et al.

Summary: The autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures are significantly affected by the percentage of DME and pressure. The oxidation of DME occurs more rapidly than that of ammonia during the ignition process, leading to the initiation of ammonia oxidation and heat release that accelerates the overall oxidation process towards ignition.
