A comprehensive experimental and improved kinetic modeling study on the pyrolysis and oxidation of propyne
(Elsevier, 2020-09-15)To improve our understanding of the combustion characteristics of propyne, new experimental data for ignition delay times (IDTs), pyrolysis speciation profiles and flame speed measurements are presented in this study. IDTs ... -
An experimental and detailed kinetic modeling study of the pyrolysis and oxidation of allene and propyne over a wide range of conditions
(Elsevier, 2021-07-27)Allene and propyne are important intermediates in the pyrolysis and oxidation of higher hydrocarbon fuels, and they are also a major source of propargyl radical formation, which can recombine into different C 6 H 6 isomers ... -
An experimental and kinetic modeling study of the pyrolysis and oxidation of n-C-3-C-5 aldehydes in shock tubes
(Elsevier ScienceDirect, 2015-08-24)Due to the increasing interest in the use of biofuels for energy production, it is of great importance to better understand the combustion and thermal decomposition characteristics of species such as aldehydes. These are ... -
Experimental studies of simple hydrocarbons in a shock tube
(NUI Galway, 2020-09-24)Chemical kinetic models are needed to simulate fuel chemistry in combustion devices and to aid in the development of new designs to reduce harmful emissions and maximize combustor performance. However, these models need ... -
A fundamental study on the pyrolysis of hydrocarbons
(Elsevier, 2021-07-10)A newly developed detailed chemical kinetic mechanism, NUIGMech1.1, is used to study the pyrolysis of C1 ¿ C7 hydrocarbons at a constant initial fuel concentration in the temperature range 900 ¿ 2000 K. We observe that, ... -
Hierarchical study of the reactions of hydrogen atoms with alkenes: A theoretical study of the reactions of hydrogen atoms with C2–C4 alkenes
(American Chemical Society, 2021-06-08)The present study complements our previous studies of the reactions of hydrogen atoms with C5 alkene species including 1- and 2-pentene and the branched isomers (2-methyl-1-butene, 2-methyl-2-butene, and 3-methyl-1-butene), ... -
The nature of stable char radicals: An ESR and DFT study of structural and hydrogen bonding requirements
(Wiley, 2018-06-28)Pyrolysis is a promising way to convert biomass into fuels and chemicals. This reaction is complex and inevitably involves a cascade of radical reactions that lead to char formation, in which some radicals become trapped ... -
On the pyrolysis and combustion of furans: quantum chemical, statistical rate theory, and chemical kinetic modelling studies
(2014-06-23)The development of synthetic methods which can convert inedible waste biomass into liquid transportation fuels is an exciting breakthrough which may reduce our dependence on fossil fuels for energy production, and contribute ... -
The oxidation of 2-butene: A high pressure ignition delay, kinetic modeling study and reactivity comparison with isobutene and 1-butene
(Elsevier, 2016-06-16)Butenes are intermediates ubiquitously formed by decomposition and oxidation of larger hydrocarbons (e.g. alkanes) or alcohols present in conventional or reformulated fuels. In this study, a series of novel igni-tion delay ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 2014-03-26)Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 2014-03-27)A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ... -
Removal of phenol and chlorine from wastewater using steam activated biomass soot and tire carbon black
(Elsevier, 2018-10-30)This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, ... -
Treatment options for the separated solid fraction of pig manure
(2012-09-20)Landspreading of pig manure in quantities greater than that required by plants can result in pollution of ground and surface water bodies. Recent regulations have placed restrictions on the application of manure to land, ...
