             abstract = "In this work, two different reduction methods for simplification 
                         of chemical kinetics, the Global Quasi-linearization (GQL) and the 
                         Directed Relation Graph (DRG), are implemented and compared for 
                         ignition of CH 4/air homogeneous reacting system. The GQL approach 
                         is an automatic and scaling invariant method for a global analysis 
                         of the combustion system time-scale hierarchy that takes into 
                         account all the original species and elementary reactions, while 
                         the DRG is a reduction method for construction of skeletal 
                         mechanism that aims at removing unimportant species and thus 
                         elementary reactions from the original detailed kinetics. The 
                         auto-ignition process is used for validation in a wide range of 
                         system parameters and initial conditions which are important for 
                         gas turbines, dual-fuel diesel engines, etc. The present study 
                         shows that for methane combustion system studied in this work DRG 
                         requires dimensions at least two times higher than GQL to ensure 
                         the same level of accuracy for the whole range of considered 
                         system parameters. And, the advantages and disadvantages of both 
                         methods are discussed.",
