Abstract:
Long-chain olefins are important commodity chemical intermediates that are currently synthesized from non-sustainable fossil resources such as C10-C14 for producing surfactants or C16-C20 for producing lubricant oils. According to the presence of green and sustainable development, it is challenging to produce long-chain olefins from renewable resources. Oleic acid (OA), one of unsaturated fatty acids, can be applied as a raw material to produce the long-chain olefins. Among the several process for converting paraffins to olefins, oxidative dehydrogenation (ODH) offers a promising alternative rough to produce the long-chain olefins from OA. This process has many advantages in terms of the ability to be operated under mild conditions with the less formation of carbon deposited on the catalyst surface. Thus, this research aimed to produce the long-chain olefins from OA via ODH over 1.0 wt% vanadium oxides supported on the SBA-15 (VxOy/SBA-15) catalyst. The effect of reaction temperature (400-550oC) and catalyst stability (2, 6, 8 h time on steam) on the OA conversion and product selectivity were investigated. It was observed that the system operated at 450oC showed the best activity performance to obtain 84% OA conversion with 36% olefin selectivity. Above this point, the olefin selectivity was improved to achieve 40% when the reaction temperature was 500oC. For the catalyst stability testing, the factor of time on stream affected the olefin selectivity. The longer time on stream promoted the deep oxidation to increase the selectivity of oxygenated compounds (40% selectivity).
