Fuels and Combustion A coal gasifier opearating at 20 atm. (e.g. Lugri gasifier) as compared to one operating at atmospheric pressure (e.g. Kopper-Totzek or Winkler gasifier) will produce a gas having Higher carbon monoxide content Higher methane content and thus higher calorific value Lower carbon dioxide content None of these Higher carbon monoxide content Higher methane content and thus higher calorific value Lower carbon dioxide content None of these ANSWER DOWNLOAD EXAMIANS APP
