ABSTRACT: Vinasseisa liquid is produced during the process of fermentation and distillation of molasses for the production of ethanol. This paper studies the conversion of vinasse into valuable materials using laser, and the characterization of the provided products. For this purpose, vinasse sample was dried and combusted for 30 seconds using Nd: YAG laser with wavelength 1064 nm at output power 60 W continuous mode. The product of this process was characterized by an X-ray diffractometer (XRD), Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) in order to investigate its crystal structure, functional groups and chemical elements, respectively. XRD results of the combusted vinasse showed Iron Silicide and Sodium Carbonate-Beta in different phases. FTIR showed several absorbance peaks confirming the presence of Iron Silicide and Sodium Carbonate. Moreover, percentages of 0.27% of iron, 0.06% of chrome and 0.01% of nickel were found using XRF.
