Ammonia 1 of 16 What can this be used to make? Fertilisers and other chemicals 2 of 16 What is ammonia made from? Nitrogen and hydrogen 3 of 16 Where is the nitrogen from? Air 4 of 16 Where is the hydrogen from? Usually obtained from natural gas 5 of 16 They are... Purified and mixed in the correct proportions 6 of 16 The gases are passed over.. An iron catalyst 7 of 16 What is the temperature? 450 degrees celsius 8 of 16 What is the pressure? 200 atmospheres 9 of 16 Why are these conditions chosen? To give a fast rate of reactions and a reasonable yield of ammonia 10 of 16 Is the reactions reversible? Yes! 11 of 16 What does some of the ammonia produced break down into? Nitrogen and hydrogen 12 of 16 So, the yield of ammonia is? 15% 13 of 16 Why are the gases that come out of the reactor cooled? So the ammonia condenses 14 of 16 What is the liquid ammonia separated from? Unreacted gases 15 of 16 The unreacted gases are recycled so... They are not wasted 16 of 16
