Effects of hydrogen additions on premixed rich flames of four butanol isomers

摘要: Abstract Butanol is thought to be a promising alternative biofuel for fossil fuels, which has four different isomers, i.e., 1-butanol, 2-butanol, iso-butanol and tert-butanol. Detailed kinetic analysis of H 2 effects on laminar rich premixed flames these butanol isomers are performed at atmospheric pressure the chemical emphasized. The detailed mechanism high-temperature oxidation combustion developed by Sarathy et al. [Combust Flame 2012;159:2028-55] consists 286 species 1892 reactions was used in this study. equivalence ratios all kept constant 1.5. additions separated from dilution thermal effects. addition major species, intermediate stable radicals analyzed compared details flames. rates production acetylene, formaldehyde, acetaldehyde, key given obtain responsible during with without additions. In addition, pathway analyses presented discussed.
