Kinetic Modeling and Optimization of Biomass Gasification in Bubbling Fluidized Bed Gasifier Using Response Surface Method

Biomass Gasification in Fluidized Bed Gasifiers Modeling and Simulation

Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed. In order to develop such model for the gasifier, as the ma...

Simulation of Biomass Gasification in Fluidized Bed Using Aspen Plus

Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...

Air gasification of palm empty fruit bunch in a fluidized bed gasifier using various bed materials

0TUse of lignocellulosic biomass as an alternative, renewable and sustainable source of energy has fulfilled part of the growing demand for energy in developed countries. Amongst various technologies applied to convert biomass wastes to biofuel and bioenergy, biomass gasification has attracted considerable attention. In this work, gasification of palm empty fruit bunch as a potential lignocellu...

Investigation of the Effects of Introducing Hydrodynamic Parameters into a Kinetic Biomass Gasification Model for a Bubbling Fluidized Bed

Theoretical and Experimental Study of Potato Shoot Gasification in Fluidized- and Fixed-Bed Gasifier

A bench-scale updraft gasifier was used as a fluidized- and fixed-bed gasification unit in three modes (fluidized-bed at equivalence ratios (ER) =0.2 and 0.25, and a mode in fixed-bed). The experiments were done in five different temperatures (650, 700, 750, 800 and 850oC). To obtain the required data to develop a thermodynamic equilibrium model, the proximate and ultimate analysis w...
