“…The percentage of total combustible components such as H 2 , CO, and CH 4 for Babul wood is better than the neem wood, mango wood, and bagasse, respectively. This is much better than that reported by other investigators (Manurung and Beenackers 1993;Di Blasi 2000;Rogel and Aguillon 2006;Wang et al 2009). …”

Biomass utilization through gasification could be a viable alternative energy source for meeting energy demands in decentralized manner. Thermodynamic equilibrium and other models have been proposed to explain and understand the complex biomass gasification process, design, simulation, optimization, and process analysis of gasifiers. Present paper deals with a comprehensive process model developed for biomass gasification in an atmospheric fixed bed rector using the ASPEN PLUS. The experimental facility of the gasifier developed by the authors has a provision for proper cooling and filtration system to derive satisfactory performance with low emissions. Thus the model developed using ASPEN PLUS is validated with experimental data obtained with four different types of feed stocks viz; babul wood, neem wood, mango wood, and bagasse. The model has well-predicted composition of H 2 , CO, and CO 2 whereas it has under predicted the CH 4 . The gasifier conversion efficiency was observed to be higher with babul wood when compared with other three types of wood due to its high carbon and H 2 and less ash concentrations.

“…Biogas is considered to be a mixture mainly of methane and carbon dioxide, with small constant quantities of air (x N2 = = 0.04 and x O2 = 0.01), typical in biogas [20]. Then, the influence of adding CO 2 up to a level of 30% was studied in a mixture with x H2 = x CO [23,24]. This covers the entire range of typical biogas compositions [20], as calculated from data of different agricultural biomass compositions [21] and experimentally confirmed in some cases [22].…”

Analysis of the behaviour of biofuel-fired gas turbine power plants

The utilisation of biofuels in gas turbines is a promising alternative to fossil fuels for power generation. It would lead to a significant reduction of CO2 emissions using an existing combustion technology, although considerable changes appear to be required and further technological development is necessary. The goal of this work is to conduct energy and exergy analyses of the behaviour of gas turbines fired with biogas, ethanol and synthesis gas (bio-syngas), compared with natural gas. The global energy transformation process (i.e., from biomass to electricity) also has been studied. Furthermore, the potential reduction of CO2 emissions attained by the use of biofuels has been determined, after considering the restrictions regarding biomass availability. Two different simulation tools have been used to accomplish this work. The results suggest a high interest in, and the technical viability of, the use of Biomass Integrated Gasification Combined Cycle (BioIGCC) systems for large scale power generation

“…Process simulation has been used to determine the best options and operating conditions for producing biofuels [5,6,[18][19][20][21][22][23][24][25][26], particularly the software ASPEN PLUS ® (Aspen Technology, Inc., Bedford, MA, USA) has been widely used. However, the models used for lignin have oversimplified the process.…”

Simulation of Syngas Production from Lignin Using Guaiacol as a Model Compound

et al. 2015

Abstract:Lignin is an abundant component in biomass that can be used a feedstock for producing several value-added products, including biofuels. However, lignin is a complex molecule (involving in its structure three types of phenylpropane units: coumaryl, coniferyl and sinapyl), which is difficult to implement in any process simulation task. The lignin from softwood is formed mainly by coniferyl units; therefore, in this work the use of the guaiacol molecule to model softwood lignin in the simulation of the syngas process (H2 + CO) is proposed. A Gibbs reactor in ASPEN PLUS ® was feed with ratios of water and guaiacol from 0.5 to 20. The pressure was varied from 0.05 to 1.01 MPa and the temperature in the range of 200-3200 °C. H2, CO, CO2, CH4, O2 and C as graphite were considered in the output stream. The pressure, temperature and ratio water/guaiacol conditions for syngas production for different H2/CO ratio are discussed. The obtained results allow to determine the operating conditions to improve the syngas production and show that C as graphite and water decomposition can be avoided. OPEN ACCESSEnergies 2015, 8 6706
