Abstract

Background: Gasification is a popular process for producing syngas from solid fuels. The focus has nowadays shifted to co-gasification using a mixed feed of coal and biomass. An optimum gasifier operating condition (OGOC) is an extremely important process parameter for gasification system. Method: A thermodynamic analysis was done to calculate this condition for co-gasifier operation. The relative product gas generation trends in co-gasification were compared with the single feed coal gasification in this study. Conclusion: An OGOC of 618°C with CO2 feed of 0.6475 moles and H2O feed of 1.3525 moles was found to be the best condition for co-gasifier operation producing 1.6429 moles of syngas (of syngas ratio 1.5905) and 54.96% H2O conversion with the gasifier product gas containing over 61% syngas. Such OGOC can be found for gasification systems ensuring the advantages of thermoneutral operation as well as 100% carbon conversion.
