“…A novel Fe 2-x Ni x TiO 5 catalyst was employed to elevate the tar decomposition during steam gasification of a mixture containing toluene and naphthalene at a high temperature of 800 °C and atmospheric pressure. Apart from tar decomposition, the catalyst suffered from deactivation due to sulfur chemisorption [100].…”

Waste biomass has the potential to produce renewable fuels and fine chemicals. Biofuels derived from agricultural, forestry, and energy crop systems are promising resources to address climate change and minimize greenhouse gas emissions. The recent advances in various thermochemical technologies for the conversion of waste biomass to value-added biofuel products are discussed. A summarized outline of thermochemical technologies such as torrefaction, liquefaction, pyrolysis, and gasification is provided. An overview of different types and sources of biomass as well as their physicochemical properties is presented. The thermochemical conversion products and their environmental benefits are considered as well.

“…It seems that the presence of Fe mainly catalyzed the conversion of toluene to benzene. Some studies suggested that temperatures higher than 800 • C increase the hydrodealkylation activity for the steam reforming of toluene on iron-based materials [72,82], whereas other researches concluded that the activity of iron-based materials leads to the decomposition of large tar compounds into small fragments of carbon species, which subsequently form benzene [83]. Therefore, it can be concluded that the higher benzene content is a combined effect of cracking and hydrodealkylation of toluene molecules on Fe active sites.…”

Traditional fossil energy sources still dominate the world energy structure. And fully utilizing biomass is a viable approach for energy transition. A bubbling fluidized bed has better heat and mass transfer, while particle agglomeration limits the development of its industrial application. In this paper, two-phase flow characteristics of a bubbling fluidized bed are investigated by combining numerical simulations and fluidized bed gasification experiments. Numerical simulations found that the bed fluidization height reached twice the initial fluidization height at the 0.054 m initial fluidization height with uniform particle distribution. Fluidized bed gasification experiments found that syngas yield increased with increasing temperature. The carbon conversion efficiency reached 79.3% and the effective gas production was 0.64 m3/kg at 850 °C. In addition, when the water vapor concentration reached 15%, the carbon conversion efficiency and effective gas production reached the maximum values of 86.01% and 0.81 m3/kg, respectively.
