A five-year project entitled "Basic Technology Development of Revolutionary Naphtha Cracking Process Using Catalyst" that will be undertaken by a team from the Tokyo Institute of Technology. It will be in collaboration with the National Institute of Advanced Industrial Science and Technology, Hokkaido Univ., Yokohama National Univ., and three PC companies. It aims to increase the propylene-to-ethylene ratio to 1.0 and raise overall product yields by 10% in a naphtha cracking process. The new technology utilizes a nano-sized (100-200 nm diameter) zeolite catalyst and a small reactor operated at 650°C (1202°F) to lower coke formation. Lowering the coke formation allowed catalyst activity to be maintained for a longer period of time.
