“…To obtain more concentrated syngas, nitrogen must be limited from the gasification agent in air-based systems while sufficient oxygen is still guaranteed for combustion to generate heat [12]. This method does not change the nature of the gasification process since nitrogen is an inert gas not involved in the reactions.…”

Gasification is an indirect combustion of solid and liquid biomass by converting them to combustive syngas. Gasification is an alternative process for the traditional combustion, in which the emission of dust and toxic gases can be minimized. In this chapter, a comparison of these two biomass-to-heat conversion processes applied on biomass is presented in term of environmental impacts and technological benefits with a hope to provide readers a basic view of choices. Gasification is classified as in term of gasification agents, non-catalytic and catalytic process, and plasma assisted process. Popular types of gasification equipment, aka gasifiers, are introduced with working principles, through which the advantages and weakness of technology are briefly discussed.

“…Accumulation of these fractions at the bottom of the gasifier within time is also a serious problem in practice. Accordingly, in case of catalysis use in gasification experiments, their effects are either not considered or it was concluded that the deviations between experimental and modeling results are based on the lack of catalytic effects in the models .…”

Aspen Plus has become one of the most common process simulation tools for both academia and industrial applications. In the last decade, the number of the papers on Aspen Plus modeling of biomass gasification has significantly increased. This review focuses on recent developments and studies on modeling biomass gasification in Aspen Plus including key aspects such as tar formation and model validation. Accordingly, challenges in modeling due to specific assumptions and limitations will be highlighted to provide a useful basis for researchers and end‐users for further process modeling of biomass gasification in Aspen Plus.

Excessive consumption of fossil fuels due to energy demand leads to an increase in the amount of CO2 emitted to the environment. Gasification technology enables clean and efficient use of fossil fuels such as coal, which cause CO2 emissions predominantly. Gasification can be utilized under several atmospheres such as air, steam, O2/CO2 mixture, etc. The reduction of inert gases (N2) and the increase of CO concentration at high temperatures in syngas provides high-quality gas. Among the commercial gasifiers, entrained flow gasifiers have many advantages such as obtaining tar-free synthesis gas, high carbon conversion efficiency, and production in high capacities. In addition, there is no limitation to the type of coal to be used. The performance of the entrained flow gasifiers can be examined by simulation programs and design optimization can be performed at a low cost. This study aims to develop a new entrained flow gasifier model for Turkish Lignite (Çan coal) using the Aspen Plus ® thermodynamic simulation program and the effects of various parameters on the synthesis gas were investigated by sensitivity analysis.
