In this study, we used Aspen Plus to model and simulate the hydroformylation of propene and octene, drawing on kinetic data from literature to accurately capture the reaction dynamics. To create a sustainable process, we integrated hydroformylation with custom-designed electrolyzers for water electrolysis, supplying renewable hydrogen at flow rates of 1.7 kmol/hr for the hydroformylation processes of propene and 1.08 kmol/hr for that of octene octene. For propene, the model achieved a high conversion of 99.8% at 70°C and 8 bar, with high selectivity reflected by a linear/branched ratio of 1.77:1, demonstrating strong efficiency under these optimized conditions. For octene, we reached an 85% conversion and a 2.35:1 linear-to-branched aldehyde ratio at ambient conditions (25°C and 1 bar), achieving substantial energy savings compared to conventional processes requiring higher pressures and temperatures.
