영문 초록

Many researchers have investigated the catalytic fast pyrolysis (CFP) of biomass to produce a high quality bio-oil (e.g., benzene, toluene, ethylbenzene, xylenes etc.). However, the low yield of target hydrocarbons and fast deactivation of the catalyst due to the coke deposition are the limitation for the actual commercialization. Low yields of aromatic hydrocarbons obtained from CFP can be explained by the low effective hydrogen to carbon ratio (H/Ceff) of biomass below 0.3. According to previous studies, the yields of aromatic hydrocarbons from biomass can be enhanced when hydrogen-rich feedstocks such as alcohol or plastics which have high H/Ceffratio is co-fed together with biomass. Waste plastic films (WPF) which contains various kinds of plastics together with starch can be a potential co-feeding material to enhance the product yields of aromatic hydrocarbons because its H/Ceff(1.2) is high level. However, catalytic co-pyrolysis of biomass and WPF has not been reported. Therefore, Cork Oak and WPF were selected as the biomass sample and hydrogen-donor, respectively, and catalytic co-pyrolysis using zeolite catalysts (HZSM-5, HBeta, and HY) was performed using by thermogravimetric (TG) analyzer and pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS) in this research.
