N. Gil, J.L. Sánchez, M.B. Murillo, M. Azuara & G. Gea
The end use of the gas product obtained in a gasification process depends on its quality. Gasifying agent is one of the main parameters that influences both gas quality and tar formation. The influence of using three different types of gasifying agent (enriched air, steam and a mixture of steam and air) on gas composition and distribution of products has been experimentally studied in a lab­scale fluidized bed plant of sewage sludge gasification. The use...
