Abstract

Syngas generation refers to the production of a synthetic or synthesis gas that is mainly composed of CO and H₂, in different proportions according to the generation process used and the raw material composition. Gasification is the referred technique to produce syngas. It can be used for different purposes, such as power and/or heat generation or for chemicals and fuels production. This chapter describes, we comment the generalities of syngas and its main characteristics and properties, also discuss its possible sources and focus on biomass waste and its co-gasification with coal and petcoke. Then, gasification modelling most common approaches are mentioned. A thermochemical equilibrium model is presented here as the model used for gasification plant conceptual design. Through sensitivity analysis technique, the effects of the reactor temperature and pressure are seen in syngas composition. This chapter enumerates the major hypothesis assumed in this syngas generation step, which must be inevitably applied in modelling and optimizing the entire gasification plant.

previous chapter Raw Materials Supply

next chapter Main Purification Operations

In this book, solid wastes from vegetable sources, forestry or agricultural wastes are of concern, as described in chapter “Raw Materials, Selection, Preparation and Characterisation”. From now, when we speak about biomass, biomass waste or simply waste, we are referring to these forest or agricultural wastes, treated in this book.

Ash slagging is important given that it prevents the formation of fly-ash.
