| Abstract | In this study, municipal solid waste (MSW) from a dumpsite was converted into refuse derived fuel (RDF) and used asfeedstock for an air-blown gasification process. The gasification process was conducted in a 10 kg.hr-1 downdraft gasifier atdifferent air flow rates of 300, 350, 400, 450 and 550 NL.min?1 at atmospheric pressure in order to investigate the quantity andquality of tar formed. It was shown that the increase in the air flow rate from 300 NL.min?1 to 550 NL.min?1 led to an increase inthe oxidation temperature from 719?C to 870?C and an increase in the reduction temperature from 585?C to 750?C, respectively.Tar was reduced from 15 g.Nm?3 to 4.7 g.Nm?3 respectively. Heavy tar compounds (>C17) e.g. pyrene and phenathrene,decreased with the increase in the light tar compounds ( |
