Power-to-X project or commonly known as Projekte Kopernikus in Deutschland, is a process involving the catalytic conversion of CO2 into valorised hydrocarbons. This is process that has received great attention from researchers for its ability in combating global warming while at the same time producing valuable commodities for chemical industry. For instance, CO₂ can be converted into propylene in the presence of hydrogen gas over supported cobalt catalyst (Pcat = 300 kg/m³). This gas-phase reaction is commonly done at 500 °C and 1 atm with an expected 90 mol % propylene yield and 90 mol % CO2 conversion. Rate constant of reaction at 500°C is 1.0 dm¹2/(mol³.s.geat) a) Design a flow reactor with the correct reactor volume to achieve 90 mol % CO₂ conversion. The flow reactor is cylindrical without pressure drop. Only reactants are present initially and stoichiometrically where CO2 was fed at 10 mol/s and 0.1 mol/dm³.

Rate constant of reaction at 500°C is 1.0 dm2/(mol.s.geat) a) Design a flow reactor with the correct reactor volume to achieve 90 mol% CO2 conversion. The flow reactor is cylindrical without pressure drop. Only reactants are present initially and stoichiometrically where CO2 was fed at 10 mol/s and 0.1 mol/dm. b) Design the most cost-effective flow reactor (in terms of surface area) that can achieve 90 mol% CO2 conversion. Assume the flow reactor is closed and cylindrical. [ c) Conversion of CO2 to propylene is a highly endothermic process with AH,m = +270 kJ/mol. It is a common practice to install heating jacket around the flow reactor to maintain the desired reaction temperature. What will happen if the heating jacket were to be non-operational during the process.
