Steam-air fluidized bed gasification of distillers grains: Effects of steam to biomass ratio, equivalence ratio and gasification temperature.
In this study, thermochemical biomass gasification was performed on a bench-scale fluidized-bed gasifier with steam and air as fluidizing and oxidizing agents. Distillers grains, a non-fermentable byproduct of ethanol production, were used as the biomass feedstock for the gasification. The goal was to investigate the effects of furnace temperature, steam to biomass ratio and equivalence ratio o...
متن کاملA semi-empirical model for pressurised air-blown fluidized-bed gasification of biomass.
A process model for pressurised fluidized-bed gasification of biomass was developed using Aspen Plus simulation software. Eight main blocks were used to model the fluidized-bed gasifier, complemented with FORTRAN subroutines nested in the programme to simulate hydrocarbon and NH(3) formation as well as carbon conversion. The model was validated with experimental data derived from a PDU-scale te...

متن کاملPerformance characterization of a pilot-scale oxygen enriched-air and steam blown biomass gasification and combustion system
Conversion of biomass into biofuels (gaseous and liquid fuels) can be achieved primarily by biochemical and thermochemical processes [2]. Although biochemical technologies are well developed and widely used for biofuels production [3], however, the types of biomass can be used are limited. Thermochemical gasification appears to be a promising technology that can exploit the embedded energy with...
متن کاملBiomass 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...
