The co-gasification of beech-wood and polyethylene has been investigated in a lab-scale fluidised-bed reactor in
the presence of four different types of bed materials (silica sand, olivine, Na-Y zeolite and ZSM-5 zeolite). ZSM-5
zeolite is very effective as a catalytic bed material in fluidized-bed reactor for wood-only gasification and cogasification in terms of high hydrogen production and CGE. Na-Y zeolite is more effective compared with ZSM-5
zeolite in co-gasification of the beech-wood and polyethylene process. The catalytic activity in co-gasification of
beech-wood and polyethylene can be ranked accordingly: Na-Y zeolite > ZSM-5 zeolite > olivine. In general,
higher amounts of steam injected in the fluidized-bed reactor and more polyethylene would lead to higher
hydrogen production in the co-gasification proces
