In this work, we are expanding the model to consider a more comprehensive kinetic expression with a wider product selectivity to explore the potential of producing a predominantly wax product on a low-temperature FT process, with an expanded model to optimize tray numbers, feed tray location and catalyst loading on trays. We are also implementing the FT-RD optimization model within the PyOMO optimization framework.
The results show that exothermic heat of reaction is sufficient to provide enough vapor load which renders a reboiler unnecessary; and side-streams of high quality gasoline and diesel can be obtained. Thus demonstrating that novel reactive distillation processes are paving the way for a more sustainable chemical process industry that is profitable, safer and less polluting.
