Özet

The main aim of this article is to investigate the conversion of leather residues into combustible gases by using a downdraft gasification technique. Second, the effects of leather residues on the operation of the throated-downdraft gasifier are explored. It was deduced that the percentage of the combustible gases, including around 11% of H-2, 20% of CO, and 2% of CxHx, varied between approximately 29% and 33% of the total produced wet gas. Moreover, the great amount of hydrocarbons was produced at almost 0.20 kgH(2)/kgC of the ratio of H-o/C-o. The most productive region for the gasification would be selected between 486.39 and 584.36 Nm(3)/m(2)h of the specific gasification rate (SGR). The optimum efficiency of cold gas was calculated as 46.50%, around 486.39 Nm(3)/m(2)h of the SGR. The overall results give a positive indication of the suitability of leather waste for both heat production and power generation using a downdraft type of gasification system.
