Abstract
Pyrolysis and gasification of municipal solid waste (MSW) were carried out in a lab-scale
fixed bed reactor in order to evaluate the effects of particle size at different bed
temperatures on product yield and composition. The bed temperature was varied from
600 to 900 degrees C and the MSW was separated into three different size fractions
(below 5 mm, 50-10 mm and above 10 mm). Particle size and temperature had integrated
effects on product yield and composition: higher temperature resulted in higher gas
yield with less tar and char, and, at the same temperature, dry gas yield increased
with a decrease in particle size, and char and tar yield decreased. The differences
due to particle sizes in pyrolysis and gasification performance practically disappeared
at the highest temperatures tested. Smaller particle sizes resulted in higher H(2)
and CO contents for both pyrolysis and gasification of MSW. Minimizing the size of
raw materials is an alternative method to improve the gas quality of MSW pyrolysis
and gasification.
