摘要：
The thermochemical conversion may be an alternative for the final destination of poultry litter wastes. In this study, the effect of calcined eggshell (CE) and calcined dolomite (CD) on slow pyrolysis and air gasification performance of poultry litter waste was evaluated. The catalysts (CE and CD) presented potential for use in the in situ capture of the carbon dioxide produced in the pyrolysis process. In relation to the gasification tests, it can be concluded that both catalysts were effective in cracking the produced tar. Reductions in gas tar concentration of 25.47 and 54.32% were observed for CE and CD, respectively. The catalysts are effective at cracking light hydrocarbons (<C5) and increasing hydrogen production. A 214% increase in hydrogen production was observed with the use of CD. (C) 2019 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
