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...

Three-dimensional computational fluid dynamics (CFD) modeling of the gasification performance in a one-stage, entrained-bed coal gasifier (Shell Coal Gasification Process (SCGP) gasifier) was performed, for the first time. The parametric study used various O2/coal and steam/coal ratios, and the modeling used a commercial code, ANSYS FLUENT. CFD modeling was conducted by solving the steady-state...

The study of biomass gasification has gained great interest in recent decades, representing an attractive process for the production energy and heat hydrogen second-generation biofuels. objective this work is to characterize composition producer gas, as well its potential. Experiments are carried out a fixed bed gasifier on pilot plant scale, bulk sawdust from pine wood used raw material. influ...

The aim of this work was the evaluation of the catalytic steam reforming of a gaseous fuel obtained by steam biomass gasification to convert topping atmosphere residue (TAR) and CH4 and to produce pure H2 by means of a CO2 sorbent. This experimental work deals with the demonstration of the practical feasibility of such concepts, using a real woodgas obtained from fluidized bed steam gasificatio...

clean hydrogen is the major energy carrier for power production. the conversion of co to co2 and zero emission during hydrogen energy production causes high capital cost. it is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. in this era, coal gasification is the most promising technology for t...

Synthetic gas generated from the gasification of biomass feedstocks is one clean and sustainable energy sources. In this work, a fixed-bed downdraft gasifier was used to perform on lab-scale rice husk, sawdust, coconut shell. The aim work find compare synthetic generation characteristics prospects sawdust shell with husk. A temperature range 650–900 °C conduct these three feedstocks. feed rate ...
