Design a chemical reactor that can efficiently convert 100 kg/hr of propane gas to propylene gas at a temperature of 500°C and a pressure of 2 atm. The desired conversion rate is 90%, while minimizing the production of unwanted byproducts. The reactor must also be safe and economically feasible, with a maximum capital cost of $1.5 million and a minimum expected lifetime of 10 years. What type of reactor, catalyst, and operating conditions would you recommend and why?
