Abstract
This study is focused on hydrocarbon production
through changing carrier gas and using zeolite catalysts during pyrolysis. A
large reduction in high molecular weight, oxygenated compounds was noticed when
the carrier gas was changed from helium to hydrogen during pyrolysis. A
catalytic pyrolysis was conducted using two different methods based on how the
biomass and catalysts were contacted together. For both methods, there was no
significant change in the carbon yield with the change in pyrolysis
environment. However, the mixing-method produced higher aromatic hydrocarbons
than the bed-method. In addition, two methods were also tested using two ratios
of biomass to catalyst. Nonetheless, there was no significant increase in
hydrocarbon yield as the catalyst loading was increased from two to five times
of biomass in the catalyst-bed method. In contrast to this, a significant
increase was noticed for the catalytic-mixing method when the biomass to
catalyst loading was increased from 1:4 to 1:9.
