✦ Synopsis
In this study, spent bleaching clay containing 26.6 wt.% of residual palm oil was pyrolyzed using a tubular furnace. Carboxylic acids ranging from C 9 -C 18 and alkanes ranging from C 16 -C 44 were the major classes of compounds found in the pyrolytic products analyzed using GC-MS. Significant amounts of monoaromatic compounds, alkenes, alcohols, ketones, aldehydes, esters, nitrogenated compounds, and polycyclic aromatic hydrocarbons (PAHs) were found in the bio-oil produced in this study. The bio-oil resulting from the pyrolysis process gave n-hexadecanoic acid as the major compound. Decomposition temperature of the adsorbed oil determined using TGA was found to be in the range of 573-683 K. Topographical and elemental analyses of the clay was done using SEM-EDX. The functional groups were determined using FTIR.
