TL;DR: In this paper, an updated survey of published mathematical reactor models for biomass and waste gasification in bubbling and circulating fluidized bed (FB) gasifiers is presented, where semi-empirical correlations are used to simplify the fluid-dynamics.

TL;DR: In this paper, an empirical model for the stoichiometry of biomass pyrolysis is presented, where empirical parameters are introduced to close the conservation equations describing the process, and the prediction capability of the model is briefly addressed, with the results showing that the yields of volatiles released from a specific biomass are predicted with a reasonable accuracy.

TL;DR: In this paper, the effect of oxygen concentration in the gasification agent was studied by enriched-air-steam biomass gasification tests in a bubbling fluidised-bed gasification (FBG) plant.

TL;DR: In this paper, the authors investigated the influence of temperature, steam concentration and internal structure of the char, on the rate of decomposition of the two tars and its evolution with time.

TL;DR: In this paper, the effects of diffusional limitations at particle scale during thermogravimetry analysis (TGA) char reactivity tests with CO2 have been investigated and the main objective was to identify the limiting phenomena that may occur during biomass char gasification experiments with CO 2.
