Journal ArticleDOI
Underground coal gasification: A new clean coal utilization technique for India
TL;DR: In this article, the potential for UCG in India is studied by comparing the properties of Indian coals with those of coal that are utilized by various UCG trials, which will help to motivate both applied and theoretical research on UCG sites in India and after detailed analysis it will provide basic data to interested industries.
Journal ArticleDOI
A C1 mechanism for methane oxidation on platinum
Preeti Aghalayam,Young K. Park,N.E. Fernandes,Vasilis Papavassiliou,A.B. Mhadeshwar,Dionisios G. Vlachos +5 more
TL;DR: In this article, a multistep methodology was applied to construct a C1 surface reaction mechanism for methane oxidation on platinum, which is capable of capturing the physics of methane oxidation over a wide range of operating conditions.
Journal ArticleDOI
The role of radical wall quenching in flame stability and wall heat flux: hydrogen-air mixtures
TL;DR: The role of wall quenching of radicals in ignition, extinction and autothermal behavior of premixed H2-air flames impinging on a flat surface was studied using numerical bifurcation techniques, with detailed gas-phase chemistry and surface radical recombination reactions.
Journal ArticleDOI
Construction and optimization of complex surface‐reaction mechanisms
TL;DR: In this article, a multistep methodology for the quantitative determination of rate constants of a detailed surface-reaction mechanism was proposed, where thermodynamically consistent, coverage-dependent activation energies and heats of reactions were derived from the application of the unity bond index-quadratic exponential potential formulation, and initial estimates of the preexpontentials were obtained from transition-state theory or available experiments.
Journal ArticleDOI
A generalized approach for predicting coverage-dependent reaction parameters of complex surface reactions : application to h2 oxidation over platinum
TL;DR: In this article, a new methodology is presented for calculating parameters of complex surface reaction mechanisms, which combines an extension of the unity bond index−quadratic exponential potential theory, reactor scale modeling, important feature identification, and model validation.
