Hydrogen production from mixture of biomass and polyethylene waste in fluidized bed catalytic steam co-gasification process

Energy from renewable source is expected to complement the energy derived from fossil fuel resources. In current research, an efficient method to produce hydrogen by blending palm kernel shell (PKS) with polyethylene (PE) waste via catalytic steam gasification is studied at pilot scale fluidized bed gasifier. This paper reports the results obtained from a series of experiment that have been performed to improve the hydrogen production efficiency. By mixing the PE waste with biomass and using those as feedstock revealed an increase in the product gas volume percent and hydrogen yield. The highest H₂ content 76.18 vol% achieved at 800 oC using 25 wt% of PE mixed with PKS. A fuel gas with a calorific value up to 15.98 MJ/Nm³ was produced which has the potential to be used in engines.
