Development of catalytic processes for the production of BTX-aromatics from biomass
제정호 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.0
The development of processes that convert biomass into fuels and chemicals are essential to reduce dependence on non-renewable resources such as fossil fuels. In this regard, research into the production of commodity chemicals such as benzene, toluene, and xylenes (BTX) from biomass has rapidly expanded in the past decade. Catalytic fast pyrolysis (CFP), which involves pyrolysis of biomass in the presence of a zeolite catalyst, is a promising technology to convert solid biomass directly into BTX-aromatics. In this single-step process, solid biomass is fed into a fluidized bed reactor where the solid biomass thermally decomposes. The biomass vapors then enter a zeolite catalyst where a series of decarbonylation, Diels-Alder cycloaddition, and oligomerization reactions occur to form aromatics, olefins, CO, CO2, and coke. In this presentation, we will discuss how the catalytic properties of ZSM-5 and reaction conditions can be adjusted to produce the desired aromatics. In addition, we will show how the Diels-Alder cycloadditions of furans can be used to selectively make the targeted aromatics.
