Özet
The gasification of Rosa Damascena residues - by-products of the rose-oil industry - was investigated under hydrothermal conditions at 500 degrees C and 600 degrees C, 35-45 MPa pressure with a reaction time of 1 h. The experiments were performed in the absence and presence of catalysts of K2CO3 and trona in a batch type reactor. The composition of the gaseous and aqueous products was determined by gas chromatography and high performance liquid chromatography, respectively. H-2, CO2 and CH4 are the main gaseous products while carboxylic acids (formic acid, acetic acid, glycolic acid) are the main components found in the aqueous phase followed by furfurals, phenols, aldehyde and ketones. More gaseous products were obtained at the higher temperature of 600 degrees C. Adding catalyst was found to aid the conversion process but the effect was only slight. Rosa Damascena residues have the potential to be a useful source for H-2 production in the future. (C) 2013 Elsevier B.V. All rights reserved.
