A coal gasifier operating at 20 atm. (e.g. Lurgi gasifier) as compared to one operating at atmospheric pressure (e.g. Kopper-Totzek or Winkler gasifier) will produce a gas having _____________________?
Correct answer: A. Higher methane content and thus higher calorific value
- A. Higher methane content and thus higher calorific value
- B. Higher carbon monoxide content
- C. Lower carbon dioxide content
- D. None of these
Explanation
High pressure favours methanation reactions, so a pressurised Lurgi gasifier produces more methane than an atmospheric gasifier. Methane also raises the gas heating value, making option a correct.
