| description | Gasification studies were performed on sub-bituminous coal of the province Centro in Boyacá state of Colombia, vegetable biomass Chenopodium album (cenizo) and co-gasification of coal-biomass mixtures agglomerated with paraffin in a thermogravimetric analyzer. Biomass synergistically promoted thermochemical transformation of the coal was observed. Experimental results were compared to equilibrium composition simulations. Ash fusibility tests of the coal-biomass mixture were carried out, which allowed to clarify its behavior, such as dry or fluid ash according to own chemical composition, during the gasification process. The experimental tests allowed determining the differences in thermal decomposition, between coal, cenizo and coal-biomass blend, which are attributable to the physicochemical properties of each one solid fuel. During the tests, gas chromatography analyses were performed to establish the compositions of the syngas. The syngas obtained from biomass had the highest concentration of CO and the lowest H2; the coal and the coal-biomass mixture were slightly minor respectively. Concentrations of CH4, CO2 and C2H4 were similar between coal and biomass. This result is consistent with the higher calorific value of the coal syngas. The production of syngas from the coal-biomass mixture had the lowest contents of H2 and CO due to synergistic phenomena that occur with the fuel mixture. The co-gasification of the mixture gave the highest syngas production, carbon conversion, and thermal efficiency. These results indicate the viability of co-gasification of coal-Chenopodium album agglomerated mixtures. In gasification of non-agglomerated mixtures of coal-cenizo, the biomass can be burned directly without producing syngas. |

Se llevaron a cabo estudios de gasificación con carbón subituminoso de la provincia Centro del departamento de Boyacá (Colombia), biomasa vegetal de Chenopodium album (cenizo) y de cogasificación de mezclas de carbón-biomasa, aglomerada con parafina en un analizador termogravimétrico. Se observó que la biomasa promovió sinergéticamente la transformación termoquímica del carbón. Los resultados experimentales fueron comparados con simulaciones de la composición de equilibrio. Se realizaron pruebas de fusibilidad de cenizas de la mezcla carbón-biomasa, que permitieron determinar si se comportarían como cenizas secas o fluidas durante el proceso de gasificación, de acuerdo con la composición química. A partir de la experimentación fue posible establecer diferencias entre la descomposición térmica del carbón, el cenizo y la mezcla de carbón-biomasa, las cuales son atribuibles a las propiedades fisicoquímicas de cada combustible sólido. Para precisar la composición del syngas producido durante las pruebas, se hicieron análisis de cromatografía de gases. El syngas obtenido a partir de la biomasa tuvo la concentración más alta de CO y la más baja de H2; el carbón y la mezcla carbón-biomasa tuvieron concentraciones ligeramente menores. Las concentraciones de CH4, CO2 y C2H4 fueron similares entre el carbón y la biomasa. Este resultado es consistente con el valor calorífico alto del syngas obtenido a partir del carbón. La producción del syngas de la mezcla carbón-biomasa presentó los valores más bajos en los contenidos de H2 y CO, debido al fenómeno sinergético que ocurre con la mezcla del combustible. La cogasificación de la mezcla carbón-biomasa dio la mayor producción de gas, de eficiencia en la conversión de carbón y de eficiencia térmica. Estos resultados indican la viabilidad del proceso de cogasificación de mezclas aglomeradas de carbón con Chenopodium album. En gasificación de mezclas no aglomeradas de carbón-cenizo, la biomasa puede quemarse directamente sin producir syngas.
