Effects of Various Biomass Materials on Lhv and Composition of Produced Syngas in A Downdraft Gasifier

Lately, biomass has received a tremendous amount of interest since biomass residues can be converted into valuable products via either biological or thermochemical processes# in this paper, sawdust pelletized and cattle manure were used to represent their effects on lhv and composition of produced syngas in a downdraft gasifier# at 750 oc and equivalence ratio of 0#25, comparable yields of methane, carbon monoxide and hydrogen were observed in the two feedstocks# the highest difference noticed was the concentration of methane; methane percent in syngas from sawdust is about 5 percent higher than that of cattle manure and is 6#9 %# maximum lhv of syngas were 7#3 and 6#4 mj/nm3 for sawdust and cattle manure, respectively# lhv of cattle manure-derived syngas was higher than that one from previuos studies#
