Biomass gasification with NiO/Olivine catalysts in fluidised bed gasifier
Tar removal from biomass gasification gas is a crucial problem in applying syngas from biomass for its downstream applications. Catalytic biomass gasification has given promising results for tar cracking. A few research groups have investigated the use of olivine for tar cracking [2,3,4,7,8,9,10]. The presence of oxides of iron and magnesium in the mineral olivine give it the ability to crack h...
متن کاملTheoretical 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...
متن کاملAir 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...
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...
متن کاملCfd Simulation Scale-up of a Dual-fluidized Bed Gasifier for Biomass
The University of California in collaboration with West Biofuels, LCC, has developed an advanced thermochemical gasification system (5 ton/day) for the conversion of waste stream biomass for the production of bio-fuels and bio-energy. The “Pyrox” gasifier design is based on a dual-fluidized bed system operating at atmospheric pressure with air. Simulation of this gasifier was conducted with a n...
