“…Proximate and ultimate analysis for the sugarcane bagasse have been carried out for simulation of mass and energy balances for the gasification process [13]. ASPEN PLUS Simulation for Syngas Production from Sugarcane bagasse using a circulating fluidized bed gasifier has been carried out by researchers [14] where a rigorous model based on Gibb's free energy minimum method has been used. Osada et al [15] used activated carbon and Titania Supported Ruthenium (RuC and RuTiO2) catalysts in supercritical water for gasification of sugarcane bagasse where complete gasification was achieved at 673 K. Effect of water density was also studied on the yield of the gas products by them.…”

“…Nevertheless, they are still an immature technology for the electricity generation due to high capital and operational costs, as well as maintenance costs and expensive control systems, which limits their development (Anukam et al, 2016). Facing these challenges, detailed simulation models were carried out to determine the technical performance and economic assessment of these fluidized bed systems (CFB model and DFB model) based on a study by Nikoo and Mahinpey (2008), Camacho-ardila et al, 2012, and Medeiros et al (2017. The synthesis of the performance conditions of the gasification processes can be found in Supplementary Tables S1, S2 (Supplemental material, SM).…”

In this work, the techno-economic and exergy analyses of two gasification technologies with integration into heat and power combined cycles are presented: i). Circulating fluidized bed (CFB) and ii). Dual fluidized bed (DFB) systems. As feedstock, lignocellulosic biomass (sugarcane bagasse, SCB) was considered. The gasification process of the fluidized-bed systems (circulating and dual bed) and the syngas conversion were performed using Aspen Plus® software. The process design includes biomass drying and gasification, syngas cleaning, combustion, power generation, and heat recovery. The SCB-DFB system has the lowest irreversibility rate and, as a result, the highest overall performance and power generation (achieving 32% in the gasification system and 53% of exergy efficiency when coupled with the combined cycle). From the techno-economic assessment, the SCB-DFB system has the lowest total production costs per unit of energy. Hence, the dual fluidized bed systems could be a more competitive technology for the agro-industrial sector to generate power from lignocellulosic materials.

“…3,10,11 An estimated 22% higher thermal efficiency and 25% lower CO 2 emission is reported using black coal in an integrated gasification combined cycle (IGCC) power plant, resulting in the lower CO 2 emission of 370 kg/MWh e . 7,12 Numerous studies [13][14][15][16][17][18][19] have been conducted to investigate the entrained flow gasification of coal and biomass using air, oxygen, steam and CO 2 . The results of CO 2 gasification showed that the yield of CO increases whereas H 2 decreases with increasing CO 2 -to-coal ratio.…”

This study investigates the gasification behaviour of bituminous coal using different reactants of CO 2 , steam and a mixture of CO 2 and steam under entrained flow gasification conditions at temperatures of 1000 C and 1200 C with atmospheric pressure. The major gas constituents of the syngas were measured using online micro-GC with a model number Varian 490, whereas the minor pollutant gases were analysed using Kitagawa gas detection tubes. A maximum carbon conversion of 86% was achieved under steam gasification at a temperature of 1200 C compared to 74% from CO 2 gasification. The higher carbon conversion from steam gasification is due to the higher gasification reactivity than CO 2 gasification. At 1000 C, the lower heating value (LHV) from steam gasification was determined to be 60%, 70% and 80% higher than that of CO 2 gasification using the reactant concentrations of 10, 20 and 40 vol. %, respectively. Using a stoichiometric 50/50 ratio of CO 2 and steam, the yield of H 2 , CO and CH 4 were increased by 56%, 106% and 35% compared to that of pure CO 2 gasification. At 1000 C, the LHV under mixed reactant condition is close to the LHV from the pure steam gasification at 1200 C. In steam gasification, increasing the temperature by 200 C from 1000 C decreases the LHV by 17 and 10% using 10 and 20 vol.% steam. The higher heating value from steam gasification is due to the H 2 and CH 4 -rich syngas compared to CO-rich syngas in CO 2 gasification. The BET surface area of the solid char from steam gasification is about 17 and two times higher than that of CO 2 gasification at 1000 C and 1200 C, respectively.
