Propene/propane separation is challenging due to the very small difference in molecular sizes, boiling points and condensabilities between these molecules. Syllabus. The LPG used as auto fuel and cooking gas in Asia and Australia, also has a very high content of butane. But it hasn’t made news as a catalyst, and certainly not one with the potential to drive global-scale industrial chemical processes. There are two steps involved in this conversion : Step 1 : First convert the propane to 1-chloropropane by in presence of sunlight . Both propane and natural gas are highly combustible and can be dangerous to work with. Herein, we report a strategy of introducing ZIF fragments into traditional mordenite (MOR) zeolite to decorate the 12‐membered ring of MOR. Time Tables 18.
