Adiabatic Fixed-Bed Gasification of Colombian Coffee Husk
In an updraft fixed-bed gasifier, the biomass undergoes four stages, known as drying, pyrolysis, reduction, and oxidation . Each of these stages occurs in a certain zone, as shown in Figure 1 . The biomass enters at the top of the gasifier and goes down to the drying zone (373 K < T < 450 K) where the moisture content is released [ 8 ].

Gasification of Miscanthus x giganteus Pellets in a Fixed Bed
Gasification of Miscanthus x giganteus (Mxgig), is highly promising due to the high efficiency of the process and the many advantageous properties of this crop. Pilot-scale, fixed bed gasification studies were performed utilizing this fuel at three temperatures (750, 850, and 950°C) to determine the process effects of temperature on gas quality and tar yields.

This paper presents a one dimensional steady state mathematical model for the simulation of a small scale fixed-bed gasifier. The model is based on a set of differential equations describing the
Modeling fixed‐bed coal gasifiers - Hobbs - 1992 - AIChE
Generalized treatment of gas-phase chemistry and accounting for variable bed void fraction were necessary to predict realistic axial temperature and pressure profiles in an atmospheric fixed-bed gasifier. Model evaluation includes sensitivity of axial temperature profiles to model options, model parameters and operational parameters.
Gasification of biomass in a fixed bed downdraft gasifier--a
This study presents a model for fixed bed downdraft biomass gasifiers considering tar also as one of the gasification products. A representative tar composition along with its mole fractions, as available in the literature was used as an input parameter within the model.

US20170275543A1 - Downdraft Fixed-Bed Gasifier for Producing
A downdraft fixed-bed gasifier for producing product gas from pourable biomass particles includes a gasifier container, a gasifier component, a feeder, an air supply inlet, a grate and a product gas vent. The gasifier container has a larger diameter than does the gasifier component.
Biomass Gasification, Gasifier Design, Gasification Chemistry
The fixed bed gasifier generally operates with high conversion of carbon, high residence time, low gas velocity, and low ash flow as mentioned in Golden, Reed and Das (1988) and Carlos (2005). The major problem occurring in fixed bed gasifiers is with the removal of tar; however, current development in thermal and catalytic conversion of tar
