This study on coal devolatilization: (1) surveys known experimental research for information needed in modeling coal gasifiers, (2) identifies the capabilities of existing experimental apparatus, and (3) formulates a research program to fill the infomation gaps found in the above survey. The characteristics of three gasifiers, British Gas/Lurgi, Texaco, and Combustion Engineering are emphasized; a conceptual description of devolatilization phenomena occurring in each gasifier is provided as a basis for the literature and apparatus surveys. Devolatilization and related phenomena govern the yield of tar and the heating value of the product gas from the British Gas/Lurgi gasifier, and apparently limit the range of soot- and tar-free operating conditions for the Texaco and Combustion Engineering gasifiers. The existing experimental data and other pertinent information on devolatilization for modeling these gasifiers were found inadequate in the areas of: primary pyrolysis, secondary reactions, and interactions of these reactions with physical mixing. Experimental equipment suitable for the necessary research on coal devolatilization is generally available in existing facilities, with required additions or modifications being relatively minor. A comprehensive research program is recommended which can apply these facilities to fill the outstanding informtion gaps.
